Hi CA Traveler,
You would need to disconnect the battery bank and run the 'house' on just the converter. Almost always some charging is going to be going on. I wonder how power factor 'fits' into that equation. I know my PD is 0.7 power factor. Does that mean using 30% instead of 10?

My thoughts on efficiency of the Kill-A-Watt approach. The converter is only used to supply house loads while on shore power so the Kill-A-Watt power used by the house loads would be higher the power used from the battery for the same loads. I’d probably use 10% for the converter. My Magnum ME2012 specification says 95% peak efficiency so I’d probably use 10% for it.
There are also efficiency in the solar system to consider like controller efficiency and weather, mounting, location, etc.
If I was going to consider efficiency I'd add 10% but overall I’d likely just ignore efficiency because I’d add a margin for the solar panels anyway. :R
