I've used them a few times and have them on my home due to a small shade issue. Like mentioned the monitoring is great, lots of data. Never had a problem with any parts. Jesse Sent from my iPhone > On Oct 14, 2015, at 8:22 PM, Marco Mangelsdorf wrote: > > Hola amigos y

Re: [RE-wrenches] Racking for Steep Roofs

Thanks for the responses. I called UniRac and IronRidge who both confirmed they max out at 45°. UniRac said anything over 45° is considered a wall and requires different testing and certification. They said the primary concern is the end clamp which holds the module by friction only.

Re: [RE-wrenches] AGS sensitive battery charger

We are not really advocating doing this. It can cause nightmares in service and support. If one really knows what they are doing, it can be done (and has been done) but mere mortals should not be attempting to do this. I would get a real AC to DC charger. If IOTA isn't good enough,

Re: [RE-wrenches] AGS sensitive battery charger

What about the Morningstar Relay Driver? You could use one port as battery voltage sense, another to control the gene start relay, third to sense generator voltage and 4th to control AC relay via a timer to allow generator warmup time. Bruce Geddes Technical Director Freedom Energy Ltd

Re: [RE-wrenches] AGS sensitive battery charger

Exactly! And fully programmable voltage, charge timers, equalization, etc. I’ve been begging Magnum Energy to do this. About 4 years ago they started telling me they were working on it. I guess they don’t realize how many are needed. I sell lots of Iota because I can tweak the voltage but

Re: [RE-wrenches] AGS sensitive battery charger

Wouldn't the Atkinson GSCM generator start module do what you need? It can send start and stop signals based on voltage. I'm not sure if those are still being made.http://atkinsonelectronics.com/manufacturing/product_pdfs/GSCM.pdf Bruce Erickson Mendocino Solar Service PO Box 1252 Mendocino, CA

Re: [RE-wrenches] AGS sensitive battery charger

The midnite classic 250 can do this fine. Rectify the generator 110vac to around 165vdc and feed into classic. Use Aux functions to start and stop generator based on battery voltage or SOC %. Roy Rakobitsch NABCEP Certified Small Wind Installer® NABCEP Certified Solar PV Installer® Certified

Re: [RE-wrenches] AGS sensitive battery charger

Sorry boB, I retract my advice then :-) Ive done it fine (I do like to use big filter caps on the input to clean up ripple) and keep close tabs on whats going on. My listeroid has been running into an MX60 for many years (7 or 8 years) without issues at around 3kw into 48v bank, and has proved

Re: [RE-wrenches] AGS sensitive battery charger

Yes, but how do you integrate a sensor with an Iota? And I don't think they make a 30A (or higher would be fine, he's got a bigass generator) 48V charger I got ears, but I've never heard of such a thing. It just seems like a damn shame to buy a big inverter when I just need a decent

Re: [RE-wrenches] AGS sensitive battery charger

The industry needs a GOOD battery charger ! PFC and fully adjustable with battery shunt interface, gen-start, etc. That could be used for lots of installations like this one Chris is looking for. It's needed all the time. It's a no brainer what features it should have. I've wanted to do

Re: [RE-wrenches] Racking for Steep Roofs

The SnapNRack universal end clamp isn't going to let go at any angle. It grip the rear module face against the real with tremendous force.

[RE-wrenches] AGS sensitive battery charger

Dear people: I'm looking for an easy solution for battery charging off a generator, but trying to save the cost of a big inverter. I have a customer who needs to charge a 48V battery bank with a 30A charger off of a generator--but I need it to sense when the battery voltage is low, so that the

Re: [RE-wrenches] Racking for Steep Roofs

Garrison, I'm here in a campground in the Emerald Triangle with Jeff Spies, who works for Quick Mount PV, and so I read him your message. He suggested that you take the engineering specs from UniRac and IronRidge to the AHJ, showing her pullout and shear capacities and

Re: [RE-wrenches] Racking for Steep Roofs

Did you look at Unirac SunFrame? It uses shared rails and a continuous cap strip. The installers can also set the modules in the rail which is really nice on steep roofs. If you are in a freeze/thaw climate contact me off-line because there’s a subtle thermal contraction consideration to
