[RE-wrenches] evergreen panels diode problems

[Bill Brooks]

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.

Bill.

Jay, there was a bulletin from Evergreen earlier this year about their
modules being used in positive ground systems. 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.

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
