Inverter creating hot skin!
I recently wired my Thomas vista for shore and inverter power. Both systems are grounded (or bonded) to the wirebrushed seat rail w/ a 3/8” stainless steel bolt and ring terminal connectors. The shore power is working great! However, when I turned on my xantrex prowatt 1000 inverter yesterday I encountered a big problem- my non contact voltage detector went off whenever I moved it close to *any* metal part of the frame/chassis. Scary! The inverter appeared to working normally otherwise, although I didn’t attempt to plug anything in before turning it off. This particular model has a “chassis ground” connection in addition to the positive and negative 12v connections, and that’s what I used per the instructions to connect to the chassis frame. The negative goes to the shunt of my battery monitor, which is connected on the other side to the battery negative. The inverter manual states “the neutral conductor of the inverter AC output is connected to the chassis ground. Therefore, when the chassis is connected to ground, the neutral conductor is also grounded.” I’ve read a few forum posts that suggest this is the possible culprit.
I had previously planned on hardwiring the inverter to an ATS, but given the hot skin I’m not sure how to proceed. Perhaps hardwiring would circumvent the ground/neutral bonding issue.
Anyway, any advice is much appreciated! This stuff scares the hell out of me and I like to play it as safe as possible.
