How to ground a solar charge controller and solar panels to a vehicle? More details... Solar Powered, Electric Tractor? Answered
Solar Charge Controller problem... For my university capstone project, my team and I are converting last year's DIY conversion electric tractor into a self-sustainable solar powered, electric tractor. Yes, we will be mounting solar panels on a tractor. It will not be for agricultural uses (yet) but it will operate as a campus' fleet service. We have four 12v deep-cycle batteries (total 48v) that will be charged with two 290v polycrystalline solar panels. The solar charge controller manual said that we needed a GFDI (ground-fault detector interrupter) because of an UL compliance but we learned that it's for residential installations... One of teammate was told that we should not ground the controller onto the tractor but he doesn't know why... is that true? We are all solar amateurs. We know how a car is ground and why things need to be ground, but if we don't ground the controller into the tractor, where can we ground it? Help...? Please and thank yous. :) I will gladly provide more information if needed.
