Alright, im doing testing. Here's what I've found so far.
The negative from my 48v battery is grounded to RV chassis. Im assuming this is happening through the 48v to 12v converter, because the output of the 12v side is grounded to a common ground screw on the frame.
The inverters do have continuity to the RV frame. Touching one of the screws on the inverter case to the frame confirms continuity.
There IS a neutral-ground bond when isolated from the grid! I confirmed this by doing the following;
While hooked into the grid via a 50 amp RV cord, I tested continuity between the neutral and ground right at the output of the inverters. Good continuity.
I unplugged the 50 am RV cord (forcing it to island), and I STILL have continuity between Ground and Neutral. Is the inverter bonding these itself??
edit: i also confirmed no AC voltage between battery and chassis on either positive or negative.
