Xantrex Freedom PSW inverter anomaly

[pmsherman]

I ran into an operating anomaly with my Xantrex Freedom 1kw PSW inverter last night. I'd been using the inverter to provide AC power for the Dometic fridge for over eight hours of driving in 100 plus degree temperatures. When we arrived at our destination, I plugged in to shore power (verified good with a meter) and discovered that the inverter's transfer switch failed to switch to pass the shore power through the inverter.

I disconnected the DC power to the inverter using my installed cutoff switch and got an E01 inverter error; no DC power available. At this point, I still had no AC power after the inverter. Restoring DC power to it started it up again, providing power to the fridge.

I again disconnected the DC feed to the inverter and cycled the AC breaker feeding shore power to the inverter. Now, the transfer switch had changed state and was passing shore power through the inverter to the fridge. Disconnecting the DC feed to the inverter has its display now showing 0.0 (V), the normal display when AC shore power is available and the battery is disconnected.

Has anyone else ever seen this happen to this inverter?

First, it would have been very helpful to know the actual Xantrex inverter model number. However, I can say I have never had such a situation occur with my 817-2000 (Freedom X 2000 120VAC). In my opinion only, the inverter worked properly and the issues experienced were due to the operation of the unit and nothing else. If shore power is not good or right, the Freedom X inverter will not transfer power, that is how it was programmed to work. Because it did not transfer power, it was forced by the user to experience conditions other than a poor shore power connection or bad AC power. If working now, no worries, the inverter was doing its job even if its operation was suspect.

First off, I never cut DC power to my Xantrex inverter while switched "ON". I use the on/off power switch to power it down and allow the transfer switch to close the transfer relay for AC operation if ever desired.
