OK, it is an inverter/charger. Came that way from the factory. Sorry for the confusion. Right now we are waiting for the inverter/charger to be returned from the Xantrex service center. It's the replacement for the Freedom Series 458 which was installed in 2006.
That said, I was not asking what I needed to fix it. If the budget would allow I'd put in a new inverter/charger and be done, and let everyone know of the poor customer service Xantrex has. Right now I have a 12V trickle charger set up to charge the batteries when on shore power or on genny and I want to be rid of that before we start our camping this year. I was just asking if I was missing anything in my thought process.
