Ah, I figured. I was thinking at at 2.5 - 3.0 kWh per mile, the Prius must be able deliver substantially more than 1.3 kW, even if it’s not a full rechargeable EV.He's not running it off the large DC battery bank, but off the smaller 12v circuit in the car. You can run off the larger bank, but it is much more involved and needs some prewiring and a 240v UPS conversion. 1300w will easily run our modern energystar large 27 cu ft refrig/freezer, an LCD TV and some LED lights. That's all one needs for temporary power if you have wood heat backup and a propane stove or cooktop. We can power 2 refrigs, a freezer, and essential lights on a 2K generator. Fortunately our water is gravity fed.
Yeah, our big draw is the 3/4 hp well, and you’d hear the generator work when that would kick on. I was able to shut down our electric water heater, and we just used the bathrooms plumbed to boilermate water heater. I also shut down all electric resistive heat, but left our two minisplit heat pumps energized. The generator was big enough that I just left all refrigerators and TV’s (too many of each) plugged in, and used them at-will. It struggled more over imbalance (eg. 10 amps on one leg with 2 amps on the other) than it did with total load (eg. 20 amps on each leg, well balanced).
Each time I thought I should maybe put some effort into re-balancing my panel, the load balance would reverse. It’s just hard to balance a whole house to within an amp or three, when that’s smaller than the draw of an individual microwave or refrigerator, esp. when the modern house might have several of each.
