Problem with Xantrex Freedom 458 Inverter
Last month my wife and I were traveling through the area of Sequoia National Park and Yosemite, in California. When I plugged into the 50A service in a campground, we lost all coach 12v and 110v services. I could not find any problem, reported it to the camp owner and an handyman checked the power on the supply post: he found a fault on the neutral and, as I understand, if there is no neutral, the voltage between the two 110v feeds results in 220v across these two feeds and, I think, That's what caused the drastic failure. We went to Camping World in Fresno and were told that they could only help us in about two to three days. Then we went to Paul Evert's and Patrick was very friendly and assumed the problem to be with the inverter (possibly $2,000 to $3,000), but the electrician that could actually diagnose it would only be available the next day. We, then, decided to head up home in Arizona. At home I found new inverters for about $1,000. But I had the time to investigate the problem on the internet and diagnose it in the motorhome: opened up the inverter and found a .25A fuse (fuse F2) blown in the AC circuit board. Bought a pack of 4 fuses at Radio Shack for less than $4, replaced the blown fuse and everything was back to normal.
I've attached the troubleshooting guide for the Freedom Inverter.
