I agree and had no problem installing the new unit but it still makes same noise. If true that there is a service bulletin out to fix problem why is Xantrex shipping a new unit expecting me to repair. It will be in Shop to be thoroughly inspected by authorized service on Thursday so will see what actually shows up. Sounds like it was a common problem but no one I have discussed with has any knowledge until today.

We have a 2003 Allegro Bus with Freedom 458 Inverter/Converter. The unit periodically makes a noise similar to flexing a piece of sheet metal. This has been ongoing for about a year and is loud enough to wake us at night. Xantrex tech support said it was a sign that unit needed replacing so we purchased new and installed. Right out of box same noise. Called Xantrex back and initially said nature of the beast and ignore but this is hard to do. Batteries are good, everything works great, shore power is constant but noise continues periodically when charger is on. We turn off charger at night and noise goes away. While in Mesa Arizona area we called Xantrex authorized repair facility and they instantly said it was a faulty module in unit and there has been a service bulletin concerning issue and that any new unit should not have a problem, they think they will be able to repair. I called Xantrex back and they agreed and said problem could get worse. Other than being noisy no one seems worried. I am beginning to run p sizable costs with new units and Xantrex warranty which covers repair of their brand new unit but not the removal and replacement to fix. Has anyone else experienced similar problems?
