[RE-wrenches] Utility disco DC?

Hello Wrenches Can the lockable utility disconnect be DC? Has anyone tried this? On an add on system we found this had been done. It would be convenient to use this method. Thanks, Drake ___ List sponsored by Home Power magazine List

Depends on utility probably but most around here specify AC disconnect. Probably since they only really speak one language. erika ___ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options settings:

One of my previous colleagues negotiated this on a high profile project in a new jurisdiction. The inspector didn¹t have a problem with this. You should definitely talk to the AHJ. It¹s not a difficult case to make: no PV input = no inverter output. Good luck, David On 9/2/08 2:56 PM, Drake

Wrenches, I had promised a followup post on what I learned when I inspected this client's batteries. The short form of the original issue (original post query is at bottom): client had as recently as June been able to EQ from his array to 31.1V, now couldn't get past 30.7. There are a few good

And one final question: In my original post I asked if deionized water was the same as distilled water. Nobody addressed this question. The customer said he investigated (Wikipedia, I think) and found no difference. Any other opinions, or (even better) definitive answers on this? Thank you,

Re: [RE-wrenches] Followup to Surrette Battery Question

Allen Sindelar was polling for information/opinions about deionized water versus distilled for lead battery top-up. Since genuine steam distilled H2O can be bought for $0.69 per gallon, why take chances on anything else? There are enough other possible problems without creating more for ourselves.

Re: [RE-wrenches] Inverter temp spec for cold regions

Hi Matt - I think I know which site you are referring to, and the issue there was not an inverter temperature problem. The units were running at or colder than the rated minimum temperature for GT's... and other than for the LCD not being very readable this is not a problem. We routinely test

Some of the single point battery watering systems have a pressure regulator that plumbs right to the water tap with a small filter. Apparently we in the solar business are more anal about using distilled water than many other battery users. Ray On Sep 2, 2008, at 6:46 PM, James Surrette
