New Inverter Charger, wiring question
I just installed a new inverter/charger with an automatic transfer switch and it appears to be working properly but I am confused on the ground wiring and want to make sure I don't have a problem down...

he has a spare charger/converter
yes ground to the frame with the Ground lug
but run a NEG wire all the way to the batteries
do not use the frame for the negative path
do not ground the inverter to the NEg cable/the batteries
the negative power path and the safety ground/frame path
are two separate physical and electrical paths
never mine that they will read continuity with a meter
they are individual physical circuits
connecting the inverter ground to the NEg cable/battery can induce AC into the DC path
it also removes the safety factor.. the safety factor to be real the ground is frame ground, not battery negative
Just to clarify; Neg (and pos)cable from new inverter is going directly to the battery, ground from inverter is going to frame, same place as old charger, neg from house batteries are going to frame.
