[RE-wrenches] Ballasted ground mounts

We were using 6" concrete slabs poured in parallel to accommodate front & rear legs of the ground mount. 1 slab per front 7 rear set each. The magic # was 18#of concrete per sqft of module to safely counteract the 90 MPH/ 3 Sec microburst uplift.

Re: [RE-wrenches] Insurance for solar design and inspections
With General coverage I have been told if there is a issue with an installation & we did not install issues would be covered but if we install it they do not insure our work.. If we sub it out it was/is covered. ___ Dana Orzel c- 2087217003 e - d...@solarwork.com --- Begin Message --- According to my agent, general liability does not cover design problems, whether we wrench it or not. That is what an Errors and Omissions policy would cover, and what a previous agent mentioned to me in passing after selling me general liability for 10 years! They could offer me an E policy for several thousands of dollars, so I shopped it around and found coverage for a fraction of that cost, from a reputable company. I have not considered an inspection insurance policy, mostly because my agent inferred that that type of work would be covered under an E & O policy as well, but I've never asked that question directly. So, something to add to my list for Monday... Howie Sun Catcher On Sun, Mar 10, 2024, 6:23 PM Dave Tedeyan via RE-wrenches mailto:re-wrenches@lists.re-wrenches.org>> wrote: Hi All, I have an insurance question and am very curious about how others deal with this, or don't. People will sometimes ask us to either do some design work for a system that we will not be installing, or to inspect a system and give my professional opinion about it. These are two separate work situations. Recently, our insurance agent brought it to our attention that we should have insurance specifically for these kinds of work, and it is not something that is covered under our general liability (contractors) insurance. Their recommendation for design work is to get "professional liability" (errors and omissions) insurance. Even though I may do one or two designs a year, we are looking at a roughly $12,000 policy. This would be meant to cover us if I make a mistake in the design that leads to some sort of failure or fire. Their recommendation for the inspection type work is to get essentially a home inspector insurance policy for about $2400 per year. Again, this is something that we do a handful of times per year. This insurance is meant to cover us if I inspect a system and miss something that then ends up being a problem or a hazard. With a brief conversation with a lawyer acquaintance, he thought that I may be fine with out these insurances. It sounded like I should have something in my service contracts that would essentially say something like "we will do this work to the best of our ability", and then if something does go wrong and the homeowner takes us to court, it is upon them to prove that we missed something that a reasonable person would have caught. My business manager does not like this because we could still have lots of lawyer fees and have to show up in court if we were to get sued, even if the problem was not caused by a lack of diligence on our part. So my question to all of you is, do you have these insurances? Or do you just not do designs and inspections unless you are actually turning some wrenches on the site so that your general liability insurance covers your work? Or, is this a case of our insurance agent putting ungrounded fears in our head? Thanks for your thoughts. Cheers, Dave -- [Logo]<https://www.sungineersolar.com/> Dave Tedeyan, P.E.

[RE-wrenches] Home grid stacked battery heating
I know we have had this run thru before & wanted to see if any new options for heating LI batteries. I have an 8 pack of Homegrid LI batteries that is off grid with Radian 8048a. Originally, they were not going to be there for the winter, now it is a possibility they may visit. Plenty of solar 6KW+, hopefully generator back up waiting on delivery currently. Currently located in main room high ceilings/log cabin. Looking at creating an insulated closet & using terrarium heaters controlled if over 51volt heater on AC from inverter. Or just boxing in with 3-4" of blue board Styrofoam.. Has anyone else done something similar? Has anyone done this & it did not work? Thought & suggestions... _____ Dana OrzelGREAT SOLAR WORKS!

Re: [RE-wrenches] Outback Radian Generator Charging
2200' EL should not influence the generator, seems the first 4500-5000' are covered like sealevel. How old is gen? Have you been into the settings menu as well as the Wizard? I have found settings in one and not the other that definitely effect the overall parameters. A call to OB might shortcut your Q. ___ Dana Orzel c- 2087217003 e - d...@solarwork.com --- Begin Message --- Hello wrenches, We just installed an GS8048a Radian build with Mate 3SL controller (no Optics). We are having some with charging from the generator, as the generator charging seems to be limited to about 4500Watts +/- (20amps AC) when charging through the Radian. It is a Kohler 8.5RES generator and we have the AC input limit set to 30amps and the Gen input set to 30amps. The house load is only about 200Watts when we are charging. The system is at 2200ft of elevation, but I don’t know if that makes enough of a difference. The Gen output voltage seems pretty good and holds around 234V-236V while charging. Any thoughts as to why it may be limiting would be appreciated.

[RE-wrenches] On Gens : 2007 Kohler: Wrenches, can you help with parts or smarts?
REF Hours on Generators: Air cooled 3,600 RPM = 80 Mph 5000 hours x 80mph = 400,000 miles Water cooled at 1,800RPM = 40 MPH 5000 hours x 40mph = 200,000 miles Both are a lot of hours but 400K is till a whole lot of wear & tear. I got to thinking about all the other impacts & considerations: * Low elevation VS high elevation * Light loading vs heavy prolonged loading * Air flow & operating temps? * Warm up & Cool down cycle VS on & off. * Synthetic oil VS dinosaur oil? Synthetic = 4x the life & still better than dino oil when it was new. * Are they exceeding the oil intervals because they are always adding & adding oil due to consumption? * Rodent impact on wiring Generators do not have tires but still carry the same maintenance responsibilities as a vehicle, & typically do not get cared for like a vehicle that you climb into & trust your life with. My 0.02 experience is that as long as they are operating all is good & get cared for mostly when a crisis occurs. What I like to call "recycled ignorance." ___ Dana Orzel c- 2087217003 e - d...@solarwork.com --- Begin Message --- Hello Mick, Here is what I'd do: Check compression on each cylinder, look for psi of about 90(ish). Also verify they are about the same (within a couple of percent). If its way out of this range, stop here. If they think they've gotten at least 5000 run hours, I'd stop here. These air cooled machines can last longer if well taken care of, but that is the design life. I have a few Kohler air-cooled with >5000 run hours so it can happen. I'm a fan of checking the integrity of the alternator/rotor with an excitation test but you may be limited in what is possible with a cooked controller. You can ask me direct for more details on this. Probably the controller is cooked and that's it, but I have had lightning to more things to generators. I would try the parts for techs but here in Colorado you can also call Power systems West in Aurora. They will need make, model, serial number and they can price out the part for you. This will at least get you a best case price for replacing the controller. You can't rely on interchangeability of these controllers. There are often changes that need harness modifications.

I've not seen a Magnum have power quality troubles, but they are not the "grid" either. My experience is that they are similar or a bit better than Outback, but certainly have measurable THD in the 4 to 5% range. Its almost always finicky loads, and the inverter has always been within its tolerances, so I doubt you have an actual warranty issue. However, I have seen inverter output get strange after lightning damage, which is not covered under warranty either. You need a decent meter that can measure THD, and can capture the peak voltage of the waveform. A good oscilloscope is even better, so you can see the waveform. Stuff like clocks not keeping time, or certain digital controls on certain appliances not functioning, is not a warranty claim. Lights dimming, or LEDs flickering is not a warranty claim. These are normal living off grid, and the only thing better than a Magnum for power quality is Exeltech in my experience.

Re: [RE-wrenches] Retail price lists
Every time in the past that I have “priced out” a project, the client has shopped it out including purchasing some equipment & then expecting me to still do the install. It is not worth the headache. Relax and let these people go. I did one 2 years ago (can you say Amnesia?) and it turned into they bought equipment from 4 venders, had plans done by an electrician that was not experienced enough to do plans, had someone else pull the permit. I got to talk with our inspector & his description of the end installation was “what a S$%$T” show”. Sell an installed package. Folks we are professionals who are in business to earn a living & a retirement, we deserve respect, so many people think that solar is this “hobby type of thing” & not a real business because they managed to install a PV module on their van with a battery & an internet inverter & they did not blow anything up (of course all with no fusing).

The pump you are looking at doesn't even give basic flow rates at pressure. (2nd clue it sucks) Max head is basically where the pump quits pumping, and the 8 GPM rating is at no pressure at all. I'd "guess" it would pump maybe 4 to 6 GPM at 40 ft of head? Also, add extra head for the friction losses in the pipe. That can be looked up (just like wire losses) for the size pipe and flow rate.

[RE-wrenches] HomeGrid Battery Experience
I installed a 400AHR set of Home Grid on an existing grid OB Radian system replacing AGM batteries. I had to replace the FM 80 CC for an Fm 100 as the FM 80s were to sloppy on their finish voltage [the microprocessors are too slow]. I received 2 damaged [warped] Top sections with the BMS before I could complete the installation. The shipping boxes were stout & fine so I can only assume that the defect was factory based. HG sated that they open & check every battery box as it come in from China… Hopefully now they will check the BMS units too. Since completion though the system has been working smoothly as in no issues. Grounding straps on the left side secured the battery set together on the left, but the right side relies on gravity to keep the individual batteries nested which is interesting as the right side is where the battery interconnects are located. I would like to see a set of straps typ. Of the left side on the right side to tie the pack tight, literally someone could lift the right side up under load & cause a lead separation & major sparky event. No conduit box on the back just a couple of compression TA’s to secure the battery cable out to the inverter. Communication with Home Grid was very good & they sent me a com box to allow them to look in on the battery bank though with no internet on site that was a miss. Oh yeah the assumptions at the factory level. **Last item - they charge to a lower voltage setting than almost all other LI batteries so check as to whether your CC can stop that low. I think it was 52.4vdc? That said I am sure that I will install more sets of Home Grid batteries. Neat clean look finished.

I have had awesome experiences with Fortress, and I have been looking for a chance to try HomeGrid as well. I think the stack idea is really cool!! I know that this is extremely nit-picky... The only thing I've seen so far that I don't like about HomeGrid is that they use 15 cells in series instead of the standard 16 cells. This just means that the voltages will be lower than what I'm used to, and amperage will be a little higher. It's not a big deal, everything will still work great, but I like the higher voltage of a 16 cell bank. I just have all the numbers memorized for a 16 cell battery bank, and while you should always double check the manufacturer's instructions, it's nice to know off the top of your head if the numbers are appoximately correct. When Fortress released their new inverterter that's essentially the same as the Solark (comes from the same factory), Solark got mad and they pushed out a new non-voluntary firmware update that broke the Modbus communication with Fortress. People didn't even know that the Firmware had changed. All they knew is that suddenly, their system wasn't working and it was shutting down randomly. It worked one day, didn't work the next. Fortress made a new firmware to communicate with Solark via canbus instead, so everything is working great again now. I don't know if Solark is finished with their vendeta against Fortress, but if Solark figures out a way to cause trouble again, then anyone with a Fortress-Solark combo could experience a coms disruption again... I really don't believe this was an accident on Solark's part. So, I guess what I'm trying to say is that Solark isn't mad at HomeGrid right now, so that might be a better bet. I personally don't use Solark. I'm leary of a company who pushes out Firmware updates that break things. One question, does HomeGrid officially support combining new batteries with old batteries? Fortress does not, they say in their documentation that you shouldn't mix different ages of batteries together. I could be wrong, but my understanding is that it should actually be fine, but the SOC will be different on the different ages of batteries... particularly when the batteries are between 30% and 80%. They'll be more tight with eachother near the top and the bottom of their ranges, but they'll drift in the middle. So I think it's fine to mix them like that, but I'm wondering if HomeGrid specifically says it's okay or if they specifically say not to do it?

It was unwired, & poorly labeled. 1200 AHR AGM Battery - 1 Radian 8KW inverter - 200 amp Generac transfer switch - No solar - Feeding a 200 amp house panel. First I explained the there were too many loads for an 8KW inverter. It could & may overload the 8KW inverter. They said "it had worked fine for 5 years & they were OK with it as is please get it back up". Replaced the existing Eaton transfer switch as the Generac controller was shot, with a Generac 200 amp Xfer switch complete with controller & transfer switch. Rewired & had to recharge the 48 volt battery from 20volt back up to full with a pair of IOTA chargers in series. The original trigger was 3 wires from the Radian to the 12 volt & AUX output to the input on the Generac controller. These were disconnected on the Generac end. So no clue or labeling there. I called Outback & they called it Redneck engineering & send me a few articles to read. Has anyone configured a backup in this manner? All suggestions appreciated, thanks & wishing you all a safe & sane season! Dana Orzel Great Solar Works, Inc.

Dual - Discoverer LI battery bank not sure on battery mode setting (written down but cannot locate at the moment) & no backup generator. Very conservative & minimalist client. I over designed past his energy load evaluation request on purpose as he did not want to have to use a generator. He has built the entire house off of 2 - small 12 volt PV systems & battery charging cordless tools. Living on site in the garage… I am very impressed with his commitment to low impact & not a wackadoodle or survivalist either. Excellent classical, bluegrass, & jazz cellist.

What battery mode? If you have Lithium batteries with communication enabled, there are certain modes that the BMS is running the charging show. I've seen the Sol-Ark throttle back charge as instructed by the BMS under these circumstances. A quick check of this would be to start the generator and see if it's on the battery management side or PV only side. It seems like you are way below the MPPT upper limit if Im looking at the correct QCell spec sheet. As far as the temperature theory. You can have temps on surfaces below ambient. This can happen in two ways that I am aware of: radiation and evaporation. The radiation effect occurs because the cold night sky (very cold) is exchanging heat with a surface. This is why you can get ice on lakes above 32F. It's very complex to model this but I doubt you could come close to lowering the temperature far enough to drive the Voc out of the MPP range. Also, there will be competing heat exchange trying to drive that temperature back to ambient. For example if you had a lot of wind in a clear cold night, the convection heat exchange from the wind would actually warm up the surface. Evaporation (or any phase change) can drop an object's temperature below ambient as well. It will pull latent thermal energy from objects in order to change the phase of the molecules. This actually has a stabilizing effect on temperature typically because it takes a lot of energy to change phase. This is why people use large water barrels in greenhouses to release latent energy to prevent freezing. Please let us know what you find out. Thanks!

Re: [RE-wrenches] Low voltage lithiums
Another issue is what charge controller are you using? I know for me with Outback products I’ve had to switch from an FM 80 to the OB - FM 100 in order to have a more accurate high-voltage cut out voltage. The FM 100 has a much more accurate micro processor in it then the FM 60 or 80 per Brad Bassett with AEE.

[RE-wrenches] Todays Mindbender
Hey All, I have gone around the barn several times with the electrician & the owner on this & come up with several ideas but none have managed to hit the mark. Ok for those of you in the low country there are people that can afford to, & do melt snow in driveways/walkways with electric mats at least for the first couple of years till they get tired of the power bills and stop melting snow with the electricity and resort to paying for snow removal or actually do it themselves. Un fortunately I cannot fast forward my client there. I have a client with 2 roofs that can hold 7KW of PV each. 14KW. The Goal is to support the house with grid tied PV & backup battery power, and address the large snowmelt & summer AC loads. This was not thought out in the beginning of the design & construction process so at this point it is an addon. Currently there is 1 - 400 A service & they are looking at a second 400A service. The second service would address snow melt in winter & AC in summer We are looking at a SolarEdge 11.6KW inverter with 20 KW of battery backup. There is a hot tub - electric, AC in the summer with 2 condensers, several refrigerators, etc.. The snow melt pulls 200 amps so it exceeds the 160 amps available on a 200 amp service. There is a 400 amp service on the house now. 200 amps x .8 = 160 amp for the house. They are looking at a second 400 amp service to handle the snow melt In the winter & the AC in the summer. I can down size 1 - 200Amp main to 150A and tie in the 11.6KW SE inverter GT feed OR install 2 - 7.6KW inverters to each of 2 - 200 A mains @ 40 A each on 1 meter, OR feed each meter the production of each 7KW array thru a 7.6 KW SE inverter. Short of an 800 amp meter/service & if possible I & the client would like to keep all 14 KW on the one meter & I say this because when they get tired of the cost of running the snow melt the full PV capacity could be directed at the house, hot tub, AC. If you have addressed this kind of out of control & have thoughts I would love to hear your thoughts & suggestions. Dana Orzel Great Solar Works, Inc.

[RE-wrenches] The Questions of product reliability
Having been in the solar biz since 1988 I can, but will not make a list of products that have come & gone; products that have been Guinea pigged on all of us, promises that have been made & not kept, equipment that has caught fire & individuals that have made unrealistic promises to clients that have really damaged the reputations of the balance of those of us who are trying to build a reliable & reputable reputations in a still growing now teen aged industry. That said I have held back on installing new product introductions & still do on say micro inverters: they get really hot & really cold & the long term reliability of a product that suffers that will suffer in the long run. I do not know of many 5-8 year old micro inverter systems that have not had at least some inverter components replaced. I remember the first micro inverter training class that I attended & the presenter kept using the term mean time to failure, & I questioned this term. The response was that the components used in similar situations should allow for a similar life span. I had this discussion today with a friend who has a unobstructed south facing roof with no shading, with a micro inverter system that is looking at expanding & wanted more micro inverters because he felt the information on what every inverter/module pair was doing was important. I asked him but what fails? The answer was: Not the Module but the inverter that was the weak link. So why use a micro invert in his application? String inverters? Less so but I have seen failure rashes of at least 1 Manu that have surfaced I have had to address multiple similar sized units replacement, at least I was standing on the ground to repair. New products for offgrid & grid tie continue to come online regularly. Today at least UL/ETL type testing awards some level of reliability & takes some of the concern out for us as installers. At this point you are wondering where the heck is I am going with this rant? * How many companies have really followed thru with their promises? * How many companies products really last as promised? * How many companies have available, accurate, & prompt/timely customer tech service? * How many companies get the replacement components out the door promptly? I really try to support manufacturers, wholesalers, & companies that meet these criteria.

You might as well be selling snake oil, you are backing yourself into a corner that has no good way out, just dont sell something that is not there yet. You can use this in your favor by telling your customer at the kitchen table that anyone that is selling you on a gen set integration better be able to back it up with facts and if they can't, Well, now the customer will have more belief in you as a result.

The module is the half cut cell type with the DC leads coming from either side of the middle of the module. The modules come with the wires taped to the back of the module. If you remove that tape, there appears to be almost no way to properly manage those wires. Is that tape meant to just keep the wire on the back of the module forever? Would that even last more than a year? I am curious what other people have done for these if they have used them or something similar. Maybe if you get the rail in the right spot, the wires will just sit on the rail...

If your use a razor only use a fresh razor blades. The moment you feel burrs stop & replace the razor as the burrs will scratch the glass.

Some sites do seem more frequent than others but overall I’ve just come to accept this and be sure to provide my clients with a tutorial of how to fix when I walk them through the initial commissioning instruction. I point out both places to unplug and highlight the greater accessibility of the 1st Mate port in the Hub versus on the back of the Mate often attached to the wall. Of course nobody remembers when it happens six months down the line either. I can also tell how often my client actually pays attention since it’s not uncommon to show up at a site for something else and discover a frozen Mate3-s. In general, I’ve just come to expect this and since it’s always fixed with a couple minute effort I don’t see it as being a major issue for the majority of my customers. As far as Hughesnet goes I also have issues at those sites. No easy way around it. Seems like Opticsre is slightly more stable than the older Blue Ion 2.0 monitoring though. Next time you speak with your favorite battery or inverter manufacturer be sure to express your dislike of this newer trend which does away with integrated hardware for monitoring. I still have a lot of “old timers” that can care less to have their monitoring online and although it makes my life easier the manufacturers need to accept that there is a large part of the off grid world that does not have reliable internet nor an age demographic that cares to navigate this new world of connectivity. There is no substitute for on site monitoring hardware that displays battery SOC. If an inexpensive Goal Zero can do it why can’t our favorite $20k batteries?

[RE-wrenches] 20,000 SQFT HONE
Hey All, I have been asked to design & install a solar backup system for a 20,000 sqft "home", autonomy requirements unknown at this time. I know. lets save the jokes. Many of you have confronted this issue with survivalist/realist types. Probably 400-600 Amp utility service is present. I generated this list with one of my engineers for the General Contractor to consider: * So there is no room for a ground mount in the back corner of the property? * If the house is in the design stage, is there any possibility for them to leave one nice, south facing roof surface that solar could easily attach to...? * Is there a possibility for a 'man cave' to be included, for a 3-4 car garage for sports cars/boats/tractors/quads... and THAT could be a standard roof surface where solar could easily attach...? * How much roof space does he have for PV? * How many broken up roof faces are there? * What size system do you estimate can be put there? * What is the size of his main panel? There are many systems out there for 200A panels backing up 400A panels is problematic, unless you want to install two 200A systems. * Does he want to run his house during a grid outage even as if he is still connected to the grid? * If the grid went down how long does he want for autonomy? * How is the house heated? * Any large loads like Well Pumps, Electric Ovens and Cooktops, electric dryers, electric water heater/on demand water heaters? Etc? * Being involved in the design is integration of the house is critical. * Both were skeptical on the roof tiles in snow country, low elevation desert is more the idea. I have an inquiry with Tesla on this point. * How much AC, and do they get summer outages? I was wondering if I could have a phone call & pick your mind as in: What have you done? What would you do differently next time? Or would you do it the same again? How much client input did you receive? Please respond directly to my email. Thanks in advance.

Really Happy with the Milwaukee M18 volt series. Various sized batteries available, & there have to be 150+ tools in the M18 series. I got into the Milwaukee 28 volt originally & what a nightmare; too heavy, replacement batteries were $$$ & life span on the battery was not good. I have been told the Milwaukee power tools have steel gears not plastic. The impacts are bomber solid. So far cold weather operation is good, no noticeable deficiencies. & I have charged them very cold so the battery charger BM is fairly smart/sensitive.

[RE-wrenches] Lithium Ion tool batteries
Hey All, For those of us that live & work in freezing winter temps - What is the overall effect on LI tool batteries stored in a frozen truck overnight, needs to be used or charged & the battery is -15˚ to 32˚F? I assume it’s the same as stationary LI batteries, though I have never seen a warning on the battery package or in the tool literature. What are you all doing with work tool batteries in freezing temps? Are you taking the batteries inside to be warm & charge at night? Thanks in advance! Dana Orzel Great Solar Works, Inc.

We are finding more and more flat roofs with rigid insulation installed over the wood decking to provide cricketing (for drainage) and insulation for the home. Installing standard stanchions is difficult because it is hard to find the rafters and also we need to use a hole saw to cut through the rigid insulation so the base of the stanchion has a solid deck to attach to. Very difficult all around! Nonetheless, we still mainly use Chemlink E-Curbs or work with a roofer to flash and seal. We have tried a few projects with the Unirac Flashloc RM product: https://unirac.com/flashloc-rm/ All in all, our crews like them although they are expensive. The tricky part is getting the engineering to work out since this type of product can be used to attach solely to the decking. We're also trying out the Anchor Products U2400 that Jeff mentioned.

I think the underlying home construction is usually the cause. Either the structure has some weaknesses or discontinuities as mentioned above, or sheathing was attached while the rafters were still wet, or the sheathing was damp when the roofing went on, etc. Then all the wood starts to gradually dry out. Our general solution is to go back, hopefully during a dry, mid-temperature mid-humidity day and take off the modules, loosen all the nuts and bolts and re-tighten the rack and install the array. In some cases we have installed locknuts with teflon washers between L-feet and rail to allow a little lateral movement. After doing all this rework, we rarely get further callbacks.

Subject: Re: [RE-wrenches] Generator recommendation request
We've seen such poor reliability with the Ecogens, that we can't recommend them
anymore. We've seen as high as 50% failure rates in full time off grid use as
backup. Charging batteries for hours is a very hard load and does not compare
to biweekly exercise mode. The failures have been fairly catastrophic,
resulting in blown motors.
The other issue with these types of pad mounted generators, as Allan just
mentioned, is that they need to be pulled and taken into the shop for major
repairs. This can quickly add another $500 to $1000 to the cost, to have a
tech with a crane pull it, truck it in, and then reinstall it later. I'm
actually just recommending a good quality portable generator for this reason in
many cases. At least the customer can take it in themselves if there's a
problem.
The alternative is to get into the bigger (>20 kW) units with water cooled
motors and 1800 RPM operation. I was surprised when I compared fuel
consumption, the big units can actually use less fuel than an Ecogen when
charging with dual inverters. The wildcat is interesting, but I'm not ready to
recommend a manufacturer I've not heard of before.
Another option I have not tried in cold weather, is diesels. I have clients in
warmer places with Kubotas that have offered excellent service. I have clients
in Alaska that love their diesels, but I'm not sure what they've done to cold
proof them.

Gary,
Interesting that you bring up Generac in response to my request. The customer
for whom I made this request for recommendations has a dead Generac EcoGen 15kW
at her property now. I don't know what's wrong with it; it had failed before
she bought the property. But she had it checked out and was turned down for a
service call at her home, told instead that it would have to come into the shop
and that basically the cost of repairs was more than replacement cost. So
another EcoGen isn't likely at this point.
Even on Generac's website, there are a surprising number of 'one-star' reviews
for the EcoGen 15 (the EcoGen 6 is discontinued). The one at my own home, an
early EcoGen 6 that Generac gave me around 2010 in return for evaluation and
review, had a throttle solenoid fail with relatively few hours on it. So I
remain cautious about Generac products.
Thanks for your reply, though.

DISCLAIMER: I have no business or financial relationship with any Generac

I have owned two Generac EcoGens in the past 10 years and am pleased with their
performance. The EgoGen is configurable using an option setting to use either
LP or NG fuel. It is warranteed for the off-grid environment, with a 500 hour
recommended interval for routine maintenance.
Even though I live in an urban area, I setup my PV system in the grid-tie
battery backup configuration. I have always used LP for fuel instead of natural
gas because of some issues we've had with natural gas reliability here in north
Texas under extreme winter weather conditions (last one here was in
mid-February).
I use my EcoGen only as a battery charger in a grid-down situation, it does not
serve house loads directly. I'll admit that most of the hours on my generator
are the bi-weekly exercise runs!
I started with the 6kW 240V AC EcoGen as a field trial participant in Generac's
beta testing of the EcoGen in an off-grid environment in 2010. Later I upgraded
to the 15kW kW 240V AC model. I very pleased with this model too.
So, consider Generac as an option too.

[RE-wrenches] Lighter tubing?
Hey all! I am proposing a [20] module, 35˚ tilt up array mounted on a flat roof in snow country - Central Idaho. Its in town, trees behind & off to the side a ways. The SnapnRack design calls for [21] Pieces of 1 ½” x 21’ sched 40 pipe +/-. I am trying to understand the need for sched 40 pipe on the vertical components of this array. Though if the horizontal members could be switched over to tube too that would be a big savings on weight. I hope to eliminate the sched 40 for steel tube [stronger metal thinner wall]. Without reinventing the wheel, has anyone approached this issue & how did you address it? Suggestions on beefy array systems that are lighter? Spec. [20] - Q-cell 340 watt modules. 5 columns of 4 modules. Snow-Load - 100 PSF. Tilt - 35˚ - The back & sides will be shrouded up to module on vertical members to prevent wind uplift. Wind - 90 MPH/3 sec microburst [though IF, this ever happened there would be trees & garbage cans flying.] Sched 40 -1 ½” pipe is 2.72#/ft. 1 7/8” steel tube is 1.25#/ft. Maybe we all use schedule 40 pipe because that’s what we have always done & locally available. Isn’t that’s what called recycled ignorance? Looking for options. In todays world marketplace I am questioning this approach. Thanks in advance. Dana Orzel Great Solar Works, Inc.

I ran the ground wire through a short length of 1/2” or 3/4” PVC conduit, to protect the copper ground wire where it comes out of the concrete. Place the conduit coming out of the concrete with the ground wire just to the side of where the mounting plate base for the TPM will be and fill the PVC conduit with a good caulk sealer to keep air and water out of this hole as a nexus of concrete, and air will corrode the copper. The TPM’s for those two jobs were made of 8” SCHD 80 steel, we had a large plate welded to the bottom with 4 vertical side supports on the pipe up about a foot. Place the appropriate sized anchor bolts in the concrete pour to match your TPM base. Both of these TPM’s have worked out well over the years. Local conditions will determine the suitability of this method.

Re: [RE-wrenches] PV direct EV charging
I just kind of ran into this issue a client wanted to charge a Tesla at night but the Tesla battery is 3.5 times larger what the than the house needed. The cost of nighttime charging shut the project down. You can operate a car charger off a 240 volt inverter at either 120 or 240 volt. The 120 volt takes a lot longer. Depends on your needs.

Re: [RE-wrenches] What would you do/say?
Succinctly put & thank you! Add to that "I did it myself what do you think?" Learning to walk away is probably one of the hardest lessons in the solar business I have had to learn (years ago). I just had a request to add batteries to a11 KW Solar Edge system that was according to the phone call that was sold to "to supposed to back up his house" without batteries??? The first time the power went out he was upset?? How do you buy a solar backup system & not know you needed batteries? Red Flag #1 This site is 9 hours away from my shop & he bragged about asking the electrical inspector during the original installation to "find something" so that the original installer would have to do a 26 hour round trip to the site. Red Flag #2 I laid out the inspection trip to do an analysis & layout of the conversion & the associated costs & have not heard back for 3 weeks. I was doing all I could to not be rude & realistically honest as to what it was going to take to pull all the SolarEdge equipment out (he wanted me to take it as trade-in towards the revamp on the system). Junk installs - Being able to say that a system would not pass inspection & therefore probably will VOID their homeowners insurance in the event of a fire related or not to the solar installation is a safe, honest & effective start with a junk installation request. You FEEL that you cannot afford this liability on your company. Ask what they feel about this. Remember their feelings & your feelings are facts! Especially gut feelings, walk away. :-]] Dana Orzel Great Solar Works, Inc.

Re: [RE-wrenches] Battery Specific Gravity versus Electrolyte Level
My recommendation on the HUPS that I install are: Use a refractometer! Check your SG, & compare all cells & if highest to lowest – If 0.02 or less no need to EQ. If 0.04 or greater time to EQ. I water every 8 weeks with a pump watering system, winter about 2-3 gallons per 2 months summer 4-4.5 gallons per 2 months. IMHO – EQ is rough on most batteries & this recommendation from NWES almost 30+ years ago has served me very well. I have many clients that have gotten 23+ years on their HUPS. I use them & I have only had to EQ once a year for 4years. 2500 AHR @48 VDC on 6000 watts tracked in a narrow N/S canyon, 4 hours of direct sun Nov 25-Jan 25. Dana Orzel Great Solar Works, Inc.

Sometimes it is so complicated that I can't expect my client to succeed. I dumb it down, just the basics, and they still get 10 years or more on a set of L16's. I think it is because battery companies are in the business of selling batteries. I appreciate that also!

Harbor Freight? 4 kW into a 4 kW charger? What's the altitude? I believe that 4 kW generator is actually only 3.5 kW continuous rated. By the time you derate for altitude, and then account for the generator not being built to be a prime power unit, its probably reasonable to derate it 50%. Then yet another thing, those gennies are 240/120 so you only get half the rated power at 120 vac, and it unbalances the load on the generator. Is that Conext 240/ 120 or just 120vac ? Its just going to be a head ache for everyone until they buy something much better. They really need something in the 6.5 kW to 9 kW range, and 240 to 120 transformer if the Conext is not the 240/120 model, so that the generator is loaded evenly.

If it's overloading, either (or both) voltage and frequency will drop below the acceptable range and the inverter will unlatch its input relays, wait for a bit, relatch and ramp up input amps until it again overloads and the cycle repeats. You may reduce either (or both) charging amps and overall input amps, broaden the frequency and minimum voltage acceptance ranges (I don't recommend this), adjust the AC output voltage of the generator, or advise them to get a better gennie.

I installed one which seemed to help, but did not stop the failures. My memory is that he didn't have much else to say at the time other than there must have been a problem in the system. My impression was they were susceptible to voltage excursions more than the average. None-the-less, I need to find a different efficient pump that doesn't cost $300 a pop.

I actually had similar problems on 120 vac, when I lived on the edge of the grid. Voltage varied from 90 to 145 vac, and cooked quite a few things like washing machine controls (every 3 months or so) Once I put in a backup power system to protect those circuits, the controls lasted for a decade.

I've long stopped installing SHW, but have used them in off grid hydronic heat systems as well. The electronics have failed on many of these pumps over the years. They seem particularly intolerant of higher voltages, even small ones, which if they are being driven off battery voltage, is hard to avoid. None-the-less while I really liked the El Sids, they were too expensive to have as many failures as they did. I'm familiar with March pumps as well, but they always seem to fail prematurely as well, for even more money.
