Hi James, that is one of the biggest questions people have about the Furrion Chill Cube part # FR67TQ, especially RVers trying to stay comfortable without relying on a huge generator setup.
Yes, the FR67TQ can run on a properly sized lithium battery and inverter setup or even a 2000 watt generator. One of the biggest advantages of this system is the variable speed inverter compressor, which ramps up gradually instead of hitting with the large startup surge you normally get from traditional RV air conditioners.
Most RVers planning to run the Chill Cube for longer periods are typically using around a 400Ah lithium battery bank with a 3000 watt pure sine wave inverter. During normal operation, the unit usually draws around 600 to 900 watts while actively cooling, then can drop below 200 watts once the RV reaches the desired temperature and the system is simply maintaining comfort. That lower and steadier power draw makes it much more battery and generator friendly, and most setups do not require an additional soft start device.
The FR67TQ also includes built in Eco modes that can limit power usage to 50 percent or 75 percent, which is really helpful when trying to stretch battery life or manage campground power limits.
Just keep in mind that the FR67TQ is the ducted version designed for RVs with existing ceiling ductwork. If your RV is ductless and blows air directly into the cabin from the ceiling assembly, you would instead want part # FR77TQ.
Are you mainly wanting to run the Chill Cube overnight on batteries, or are you looking for something that can comfortably keep up during daytime cooling while boondocking?
