can i add on-off switch connect to the main switch power and use solar power inventor 5000 watt or 12v generator

Hello,

Sure you could. I wouldn't hook it to main power switch, though, I would buy a bus bar and then run wires from the bus bar to the components that you want to power with the power source. Put the on/off switch inline in between the power source and the bus bar. I hope this helps.

Thanks,

Thanks Alex, I am trying to avoid putting more wires because the car is already loaded with punch of wires. usually when am driving I don't need the power inside. I needed only when I stop in places for one or two days. can I cancel the main switch and hooked to solar invertor or other wise I will follow your advice. but how I can solve the rear air-condition when engine is off or I have to buy external air-condition especially am trying not to make holes in the sailing .
thanks again Alex I highly appreciated your respond.

Hello,

Yes you will either have to buy an external Air Conditioning Unit or idle your vehicle's engine. In order for your vehicle's A/C to be on the engine has to running. I hope this helps.
