I just purchased a 2007 Great West Legend with a Xantrex Prosine 2.0 inverter. When running the inverter, with no load (all 120V breakers off) it still says it is outputting 8 amps at 120V and pulling about 80 amps from the coach batteries. That is like 1000W, but nothing seems to be getting hot and there is no smoke. Could it be that the converter, going from 120V back to 12V is connected after the Prosine? Could the Prosine be inverting 1000W from 12V to 120V, and then the converter takes that 120V and converts it back to 12V again and pushes it back to the battery? Should the converter be connected before the Prosine, so it is only working if on shore or gen power? Any other ideas about what may be happening? If the generator or shore power is present, the inverter shuts off and passes the power through as it should. With the breakers off in this case, there is no measurable load.
There are a few other electrical issues with this van, there is a drain on the engine battery and they just added a battery cutoff and lived with it. So, the installers of this stuff may be suspect. It may have been a few owners ago, but I want to fix it. Any suggestions welcome.
