That is a great idea! Instead of cutting the charging circuit, cut off the AC voltage into the Xantrex. The way the Xantrex is set up, the contactor inside the Xantrex is operated by the 24 v system, so right now when overvoltage is sensed it shuts off the charge circuit, which on a Xantrex is also the main cable from the battery back to the inverter. So the inverter shuts down. A pain but a better alternative to the battery frying. I’ve never thought of using a contactor to break the AC into the Xantrex! Excellent. Now if we can just get the Xantrex to work according to spec, we will have a working system with built in guards against catastrophic failure.
