You can add a 1kw inverter to any car, the 12w system will handle it just fine though not indefinitely. There's a really simple formula you need to know. P=UI P

You can add a 1kw inverter to any car, the 12w system will handle it just fine though not indefinitely. There's a really simple formula you need to know. P=UI P=Power U=Voltage I=Current Get the specs of you generator and you can see how much you can sustain while your engine is running. The inverters do usually create a square voltage "wave" rather than a good sine one, but it has never been a problem in my experience.
