Xantrex Inverter

If Xantrex still will not charge after all the testing consider just getting a separate converter to keep the batteries up.

This is exactly how I do it for several reasons

ONE: I like the Progressive Dynamics Wizard better than I do my Prosine.. NOTE.. This is mostly a matter of preference, I give them both the same marks (top end) but I still like the Wizard better.

Second.. If you are running on "iffy power" I can cut off the 30 amp branch breaker TO the Prosine, and then I have

Shorce--Converter--Battery--Inverter---Senistive loads.

That's called a power line conditioner.. Though I can't microwave all day, it will sure take care of TV's and Computers.

OK so here is the update Just as I started to disconnect the positive cable from the unit I noticed it was very loose. So I tightened it up and everything is working just fine. Lucky me!!!!

I had inverter issues that turned out to be a bad ground. It started with my old Magnum inverter after I pulled the battery tray all the way out to fill the batteries. I suspected a loose wire and told my local RV shop (Fat Chance RV and Taco Stand) that I thought it was a loose wire or bad ground. They called and said the inverter was gone (2 years old). They installed a new Xantrex and still had no power. Then they installed a third inverter and with still no power, finally troubleshot the wiring and found.... wait for it..... a bad ground.

I sent the Magnum back to the factory and they refurbed it at no charge. I have a spare.

I'm no stranger to working on equipment. I'll short the caps to discgarge them. I would rather try to fix it then send it to xantrex for repair. The rv was plugged into a 20amp circuit that kept tripping the breaker, so a blown fuse is quite possible.

It sounds like you've had a surge and blown the mother board fuse. I do not advise a novice to disassemble the inverter to change this fuse, there are capacitors in these units that can really hurt you.

To replace this fuse you must remove the case, and the smaller of the two circuit boards, you will see the fuse.

I replaced this fuse twice before I realized there was more damage to the inverter / charger than just the fuse, so we up graded to the magnum 3000 W. these are not a plug and go swap. you must do some relocating of wires and the grounds. and change the remote control panel in the coach. that is easy to do the new panel uses the same phone chord, and fits the hole of the old inverter.
that ended our problems.

"The only thing he said was left to do was to do a complete shut down. No 12v or 120v to the unit for at least 2 hours"

Time enough to allow him to finish his shift...


Try the inverter part. If it works then that's a horse of a different color.

If you are inclined there is a tiny fuse on the mother board.

is the inverter providing 110 voltage ?

I did ask the tech on the phone about the possibility of a fuse and got no answer from him

I was on the phone with xantrex and we went through several tests. The guy on the phone was stumped. The only thing he said was left to do was to do a complete shut down. No 12v or 120v to the unit for at least 2 hours
