[RE-wrenches] AUO ac moudles
esteemed wrenches, i am looking at the AUO brand of AC modules for an upcoming job. this is a 250 watt module with a 255 watt microinverter attached to the back. both carry a 25 year warranty. as we all know, warranties are only as good as a company's longevity. this is a taiwanese made product. http://auosolar.com/?sn=1037&lang=en-US todd Sent from Finest Planet WebMail. ___ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org

Re: [RE-wrenches] SunDrum Solar
I installed a system in NYC a few years ago. So far the homeowner is real happy with it. He reports in from time to time with positive feedback. I stopped in on a hot summer day and the temp. in the HW tank got up to 102 and the temp of the Sundrum unit on the roof was 112. The install of the collectors was simple and since the system does not get as hot as a typical solar thermal system you can use pex tubing from the collector to the tank. Overall I like the system.

Re: [RE-wrenches] reliable 12vdc to 5vdc converters for USB charging
Hi Jim Phocos has a 12v to 5v converter with USB output built into their Pico light. The battery in the light (4 x AA NiMH) can be charged off a 12 v PV or 12 v battery. They like to sell them with a small module and a few Pico lights. Maybe you can get just the converter from them? I just got one of the Pico lights for around the house and it seems like a solid product so far (2 year warranty). LED with 3 light levels in multi use fixture that can hang from the ceiling, fit in your hand like a flashlight or be set down with several adjustable angles makes it versatile.

Re: [RE-wrenches] [RE Marketing] Marketing] Question about Solar Tax Credit basis
Colleagues: This is related question: How does one categorize a building that holds up a solar array? I am awaiting an inspection today on an installation on an agricultural barn. In these parts, an Ag barn does not require a permit. We put a solar array on the barn in 2008 and although a permit was required for the solar, no structural engineering was required. When we installed an expansion just recently, the building department required a engineering study on the structural integrity of the building. I was told that the barn was no longer a barn once the barn is used to hold up a PV Array. To quote the building official: Even though Ag-exempt buildings are required to be code compliant there is no assurance that it was constructed as such. To use it for other than the stipulated purpose as defined in the ordinance of an Ag-exempt building, it technically takes it out of that realm and thus triggers a structural review. In my opinion, this is BS. That point is reinforced by the fact that we can't take a 30% tax credit for the cost of the "PV support structure" (the barn). I received a waiver on this project so we did not have to pay for a structural review. I now know that next time I propose a project like this to be prepared for an extra expense. William Miller At 05:52 AM 2/22/2012, you wrote: So Scott's reply seemed less ambiguous - not a chance for claiming any "dual use" costs. Julie's response made me think there is wiggle room - that the barn/shed built to put an array on top of it instead of building some ground mount structures would not work without the roof and therefore, some portion of the structural cost could be included in the system's basis for figuring the tax credit. On an intuitive level, this would be potentially justifiable (not that the tax code is ever intuitive...). Our experience supports Scott's take, since a client's 1603 tax grant application which included some building expenses was denied those additional grant dollars. I'm just trying to figure out if there is any chance for an appeal of that decision, or if the 1603 grant process was just more stringent in the reading of what I see as ambiguous language than an audit of the regular tax credit.

Re: [RE-wrenches] Fwd: AC Coupled
Larry, A Sunny Boy won't feed any power directly at a generator on the main panel: the AC on either side of the Sunny Island is separately derived, and it's my understanding that the SI can command the SBs through the CAT V link to throttle back if loads aren't sufficient. Wouldn't the Sunny Island inverters see that there is no load coming from the AC main panel where the generator is located? I would think the SI should be smart enough not to backfeed power at another source unless it sees a load. I could be wrong about this, though. Call SMA and ask. I think the main SI tech guy for SMA America is Roy Dyngen. Let us know what they say.

Re: [RE-wrenches] cycling flooded batteries is not necessary
Yes it is the lead that dissolves in water. If the volts per cell is less than 1.75 this process begins. the lead dissolved will form dendrites upon charging and these whiskers of lead can short out the plates. Most battery manufactures recommend the volts per cell stay above 1.85 volts per cell. (resting) to prevent the lead from dissolving From: Howie Michaelson To: Darryl Thayer ; RE-wrenches Sent: Monday, February 20, 2012 8:40 PM Subject: Re: [RE-wrenches] cycling flooded batteries is not necessary I had always been under the impression that too strong and acid is what softens and weakens the lead grid, dissolving the lead out of the plate. Is it really true that water is the enemy of the plates? And if equalizing on occasion is all that is needed to break up the stratification of the electrolyte in a float service, what would the suggested frequency of equalizing be if the batteries do not need equalizing for other reasons?
