I have a Xantrex FSW 3012 that seems to be working just fine. Inverts and charges great; but for the most part, the charger
is disengaged via control panel
. We are plugged into a 30 amp shore pedestal
, but also have a decent solar
array to support our electrical
habit so I need to recharge the house bank once every couple weeks. About a week ago, a marina employee was working on our pedestal
and while working on said pedestal, I manually switched on the charger
to refill our LFP house bank. The worker noted that at the point I turned on the charger, there was a 500 mA difference between the hot and neutral and 250 mA on the ground; all at the pedestal. When I turned the charger off, there was no discrepancy between the hot and neutral; 0 mA on the ground. Interestingly, there was no shore side GFCI break. I do not have an ELCI installed, but have been looking at the SmartPlug ELCI and breaker combo.
So...questions are can this be a wiring
issue on the boat
as opposed to an internal Xantrex component failure? Or does the fact that the discrepancy only occurs during battery charging
narrow the fault to the Xantrex unit itself? I would be happy to pull the unit if there was someone in the San Fran Bay area who could bench test the unit for me. Until then, I'd like to problem solve and leave the charger off.
