i just have a question i hope yall can help me work because no matter how much i look up i can’t seem to find one answer. im grounding the electrical system in my van. i have everything wired to negative and positive bus bars. from the negative bus bar, im running a 4awg wire to my chassis ground in my van. should I connect the inverter ground wire(12awg) (not the negative) to the same chassis ground spot or just connect it to the negative bus bar as well? some say to connect to neg bus bar and that’s fine but others seem to say its better to wire it straight to the chassis ground? what do you guys think?
also should I connect the grounding wire of my 40a mppt charge controller as well or not as crucial? #lifestyle source
