Positive Ground

Model Number: GS-S-100-TS
"Be careful with this panel if you are buying for an RV. It requires a funky grounding of the positive lead. This is not mentioned or shown in the wiring diagram that Costco has here associated with this panel, and it is not on the PDF on the Grape Solar website either as far as I can find. (Notice that the PDF there that the hyper link directs you to when you click on the 100W link does not include this 100W model number) The first I saw it was in appendix 2 of the printed instructions that came with the panel. I called grape solar and they were actually very friendly and sent me an RV specific diagram, but I am still a little leary of the hookup. My Camper is prewired for solar so I was hoping to just plug this in... and it would have been that way had I bought a panel without this funky gronding requirement."

Hook Up

Pros: great output
"For an RV installation Grape Solar advises that a "positive ground" is no longer required if you have a " pulse width modulated digital regulator". The regulator turns on and off so many times that the negative static charge that degrades panel performance does not get a chance to build up."
