Really need advice with a kill switch for an inverter

Does your power inverter have a remote.aka.acc wire.or is it just power and ground

 

a starter solenoid on the positive terminal would do it. get one at any auto parts store. like this http://www.amazon.com/Ford-SW3-Star...0488468&sr=8-1&keywords=ford+starter+solenoid

you'd also need a toggle switch and some wire to send the signal to the solenoid.

 

I don't think you'd have any problems with it since it is generally used to send power to the starter which is much more demanding than your inverter. However, perhaps one designed for continuous duty like this would fit your application better... http://www.amazon.com/Cole-Hersee-24059-BP-Insulated-Continuous/dp/B0064MX7US/ref=pd_sim_auto_6

 

a simple battery switch like a battery shutoff on freightliner would handle the voltage

 

If you use a fuse on your power wire (that I recommend you do) you can just remove the fuse when not in use. A cuircuit breaker for 12volt cars would also work.

 

why do you need to kill the dc side of it? If its turned off it wont draw power.
