Re: [RE-wrenches] EMP and PV modules

I've been dealing with a few customers with EMP concerns.  Just as we had to deal with the non-event of Y2K,  I think its extremely important to not exaggerate.  Saying that we will be back to the "Stone Age" is just not an accurate statement and contributes to the hype.  We've only had

Re: [RE-wrenches] grounding on metal roofs

NEC 250.4(A)4 Also states that normally non-current-carrying electrically conductive materials that are likely to become energized shall be connected together and to the electrical supply source in a manner that establishes an effective ground-fault current path. So the logic goes if an

Re: [RE-wrenches] grounding on metal roofs

NEC 690.47 (A) requires the array to be grounded, not necessarily the roof. If you have bonded the rails and modules and your grounding conductor goes back to the service you should be good. 690.47 (B) allows installation of an auxiliary grounding electrode (ground rod or building steel). Not a

Wrenches Hawaii was hit in the mid last century by a EMP, it took out most of Honolulu, this was a post war test and it did confirm what can happen. This was before micro electronics so if it happens we,re back to the stone ages. On Mon, Jun 18, 2018, 10:21 AM wrote: > inverters and charge

I’ve done a quick search of the archives, but does anyone know of the the effects of an EMP PULSE on a module? We’ve got a potentially large project to look forward to, and one developer is very concerned Jeremy Rodriguez Solar installation / Design Expert All Solar, Inc. 1463 M St Penrose
