The DC-DC converter in the PHEV outputs 2,500 watts, which kinda doesn't matter much since the 12v battery buffers the output. During the day my house averages 500w, so the DC-DC converter can easily keep up with daily demand.
The inverter can't power the whole house because its 120v. It can power half my circuits though, which includes the main living areas, HVAC blower, washer/dryer (dryer is natural gas), fridge, deep freezer...
Runtime is infinite because the gas engine kicks on whenever the high voltage battery runs low. I get about 12kWh from a full charge, so that would last about a day of normal use, or probably 2 if the power was out. There is also a trick on the van to force it to run the ICE by opening the hood. It will charge the battery while the ICE is running, and will replenish the ~12 kWh in about 2hrs.
I've got everything needed to run this setup, just haven't tested it yet.
