12V (DC) vs. 110V (AC)

I found it. It's Temp-a-Start.

Man they're really taking advantage, even moreso than the APU pricing. $3500 installed and they don't even actually power anything, just cuts on the engine with a timer and sensor.

 

Pharmphail ya got that one right brother, TAS is spensive, its something a driver has usually when it came with the truck.

 

On my freightliner, (keep in mind we use it for recreational use), I mounted a rack behind the sleeper, across the frame that holds 6 8d batteries. The invertor is wired into this battery bank. It is isolated from the cranking batteries with a continous duty JA solinoid tied to the key switch. when you start the truck it charges, and when you shutdown, it isolates them. It prevents running down my cranking batteries. Also allows us to plug the trailer into the truck for power when camping.

The weight could be a factor in commercial use as the batteries are heavy, but with this setup, it provides enough power to run the AC in the trailer around the clock when camping.

 

Your inverter's low voltage alarm and cutoff are going to start whining just shortly after you turn off your truck drawing 60 amps. That will draw the voltage of your batteries down FAST. If your inverter doesn't have a low volt alarm/cutoff. then after a night or 2 I imagine you're truck won't start.

 

Yep you were right. The remote that came with my Whistler plugged right into this one and works fine.
