The high voltage puresines cost way too much ~$3K (big an heavy, over 50lbs) and they are either 5-15kW or only 300-600W........lol
The consumer-class inverters are a lot cheaper than anything you can buy for HVDC. Though that ElCon TDC-320-12 1500W DC-DC Converter is pretty cute, and a decent price . . . I'd like to see real reviews, though.

Load will be in the 1200W to 1500W running planers and routers etc.
Those don't need pure sine wave, they'll be happy with approximated (stair-stepped) sine wave.

. . . and just use my existing 12vdc 2500W (5KW surge) puresine, but it's kind of old and big also. maybe just scoop up a 1500w one on ebay.
Have you
done the math on the input current requirement of a 1500W @ 120v inverter? You're going to need ~150A @ 12v
continuous. I used to do that, but with paralleled batteries, and you don't do it for very long without something charging in the circuit.
If you want to use your RAV4EV instead of a jobsite generator or Tesla Powerwall, your idea of a HVDC input inverter is a good one. But the car will have to be ON to tap the traction pack in any safe way. The car ON in Park and HVAC OFF would work. You wouldn't save much power by trying to bypass that, IMO, though it could be done.
