I just installed in place a 100/30 Victron Solar Controller. I'm not sure where the ground screw should be connected to. I suppose one place would be the chassis frame. But I'm wondering if it could be connected to a negative terminal on the Blue Seas bus bar I'm using. In my overall set up there is no grounding at all to the chassis frame and the chassis frame is not being used for any negative wiring returns. Any thoughts about where to wire that grounding screw on the solar controller?
Thanks.
