How to install inverter to turn off with your car?

[22mountaineer 10+ year member]

I have a 750 watt Generac Inverter. It will be used to charge cordless batteries and phones.

I want the inverter to turn off with the car. Every time I have done this, I have simply used a connector to come off of one of the fuses (load) in the fuse box, however, this one is a little bigger pulling roughly 70A at a full load.

It looks as if the only way I will be able to hook it up is directly to the battery (fused).

Do they make some type of contactor that I could use from one of the smaller fuses that turn off/on with the car (ignition)? If not do you guys have any suggestions over a simply switch, there is one on the inverter but I know good and well one of my techs will forget to turn it off and kill the battery.

Thanks a ton man. I was looking way to deep into the high side and it was throwing me for a loop.

I see you are from New Hope, ever hear of anyone needing a generator or service and repairs we are certified by Generac. Give us a call, Ryan at Bippen Electric.

Brilliant idea, i had been asking myself the same question because turning my inverter off only turned off the receptacles..
