Doug, I'd like to see the bulletin about why they could not positively ground their modules. It seems quite odd.
Positively grounding a module in general should have no effect on a typical module. As to why it helps the SunPower module, they have an explanation, but I'm not convinced it is true--it just works--and that is all that matters.

I don't remember the exact details (and I'm not at work now), but the gist was avoid positive ground till we make some modifications. Please check w/Evergreen on Monday. -Doug Pratt -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of jay peltz Sent: Thursday, September 18, 2008 5:24 PM To: RE-wrenches Subject: [RE-wrenches] evergreen panels diode problems Hi All, I"ve got two evergreen 170 watt panels with bad bypass diodes in them. In service for under 2 months. Only odd thing is that this is a positive ground system. They are running at 3 in series for a 48v system. Anybody else have problems with them? thanks jay peltz power _______________________________________________ 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 _______________________________________________ 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 _______________________________________________ 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
