Xantrex SW2000 Inverter - Reverse Polarity Fried!

Has anyone else screwed up and fried their $400 Xantrex inverter by hooking up the battery in reverse polarity by accident? It was very brief, but now the Xantrex is dead! Can this be fixed by replacing an internal fuse?

It probably can. I would think it has a reverse polarity protection diode in it to prevent this problem.

I hope it is just an internal fuse but I have repaired a few that have destroyed mosfet transistors. I think the fuse doesn't always protect the sensitive electronic devices.

I hope itís just the fuse.

I want to get an inverter but I’m puzzled on how it’s wired? Should I get one that is also a automatic converter battery charger,? If it doesn’t have a charger built in, then when on the inverter it will power converter that is also charging battery? That or I need a transfer switch? I would like to have a 2,500 watt inverter is I can make coffee and watch tv at the same time. I understand that wattage requires battery storage etc, I just can’t figure out the mechanics of the inverter, converter, plus house or gen power. I want as much auto mystic as possible. I guess I need transfer switch and relays etc.
