Inverter grounding to batt or chassis
I'm looking for some input regarding the ground (negative, not neutral) connection for my 1800 watt inverter. I need about 10 of wire to run it back to the battery or I can ground it to the motor hom...

OP here. I'll have half my battery bank on the curb side of the motorhome and the other half on the street side. To wire the batteries in a balanced fashion will take extra wire length. This is most of my motivation to ground the inverter DC return directly to the frame. I'll use a tin plated lug which is galvanically compatible with the steel frame. I can also use a chrome plated bolt so that the bolt will be galvanically compatible with the steel and tin.
I don't think the frame negative power connection really helps you.
Do you have 12v or 6v batteries?
