Re: [RE-wrenches] Battery recommendation WAS: Rolls batteries

Hey Dan, Interesting voltage numbers. How many T-105's in this system and what is the load? What is the temperature of the battery bank? Thanks, Dave From: RE-wrenches [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Dan Fink Sent: Friday, October 23, 2015 10:51 AM

APS microinverters will work. Each YC500A handles two modules each and each YC1000 handles 4 modules. https://usa.apsystems.com/ *Benn Kilburn * CSA Certified Solar Photovoltaic Systems Electrician, SkyFire Energy Inc 6706 – 82 Ave NW | Edmonton, AB | T6B 0E7 P: 780-474-8992 | F: 888-405-5843 |

Re: [RE-wrenches] Battery recommendation WAS: Rolls batteries

Dave, it's 6 T-105s and over the winter the only load is the CC and inverter. Temperature is unknown, though likely gets to -20F. There is insulation, not that it does any good if they are not charging to capture some heat. Dan Fink Adjunct Professor, Ecotech Institute IREC Certified Instructor™

Re: [RE-wrenches] Current limiting fuse at battery bank

HI Dan, All the big three have the same wiring diagrams with a positive buss and then breakers going out from there. And yes there is no main disco for the DC branches. But if your point was that the fuse could/will blow and then you have the PV/wind connected to the inverter and could

Re: [RE-wrenches] Battery recommendation WAS: Rolls batteries

Hi Allan and Jay, I second the golf cart battery option. Trojan T-105s seem to be the most bang for the buck. An 800 W array wouldn't stir up the electrolyte sufficiently in an L-16. Maybe the backup generator would. What all is she running? Drake At 06:40 PM 10/22/2015, you wrote: Hi

HI All, What is the recommendation for 72 cell 280 watt 120/240v micro inverters? Enphase don’t have one. This is on my old house. Still has a AEI-GC-1000. The modules have got to come off as well as they are old mobil’s. All just about dead. I’ve got a good deal on 72cell, 280 watt modules,

[RE-wrenches] off-grid water pump

Hello, I'm replacing an old Solarjack pump with a similar Sunpump in a tiled well about 12' deep. I'd like to find a flexible water pipe so I can leave enough coiled in the well to pull the pump straight out to dry land without disconnecting. Standard poly pipe kinks too easy. Thanks. Kirk

Re: [RE-wrenches] Current limiting fuse at battery bank

Thanks, everyone. I see I'm not the only one juggling competing concerns on the battery fuse issue. For the service call that motivated my query I think we'll leave it as is - the installation has short battery cables in conduit into an Outback system, and no easy way to mount a fuse external

Re: [RE-wrenches] Current limiting fuse at battery bank

Esteemed Wrenches; This creeps me out too and sometimes causes lack of sleep. The Midnite Solar power panel install manual shows no OCPD on in DC + main from battery bank to power panel. Easy to wire the main DC breaker to control those conductors, but then you have a "self destruct" switch if

Re: [RE-wrenches] Current limiting fuse at battery bank

At an absolute minimum a current limiting the fuse at the battery bank is required if not by the law by common sense In banks with multiple strings in the past I have fused each string I have seen banks in the past where a single battery failed and for lack of a better description the others

Re: [RE-wrenches] Can anyone identify this mounting system and module

Carl They look like the Westinghouse product. Their new name is Andalay solar ( no Seinfeld reference ). We installed one of these, very high failure rate with the enphase 190's requiring us to remove the system and replace them. All the splice rods where corroded and we had to use a sawzall

Thanks, esteemed Wrenches, I'm thinking that she would do fine with 440 A/hr of T105 REs.  Jay asked about her loads. I emailed her this earlier today: Beverly, Back when the batteries were still strong, if you ended a day's charging at 100%, what would the

Re: [RE-wrenches] Current limiting fuse at battery bank

Dan, That's right about the unprotected DC + main. Trace used the inverter GJ, so turning off DC loads required turning off the DC to the inverter - which meant reprogramming it afterward. And it used a #10 tap pigtail. Stoopid. If I have several DC loads I have

Re: [RE-wrenches] off-grid water pump

Kirk, This is on my iPhone and I'm barely literate on it compared to my kids, so it'll likely mess up... Use 3/4" SDR-9 black 140 psi black poly pipe with sleeved compression connectors. This has been used for years for hand installation of submersibles, down to 250-350'. I would guess that

Re: [RE-wrenches] Current limiting fuse at battery bank

It's ALWAYS good practice to install a current limiting fuse at the battery bank, if fact it's very poor practice not to. We're working with a lot of larger lithium ion phosphate manganese systems and I would not install them without it. As far as working on someone else's install, make your
