How to Run RV AC on Generator
In order to power up a standard rooftop AC system in an RV, you’ll need a generator rated at least 3,000W. There are also options of modifying the AC system and implementing the soft starter technologies, which will reduce the need for power to as little as 2,000W. If your current generator supports a parallel connection, you can also double its power by hooking up another one.
It’s better to turn off all other devices connected to the generator and located inside the RV. The refrigerator should be completely shut off or set to run on gas only. Start the generator and let it run for a while. Plug in the RV plug into a relevant outlet (use an adapter, if needed). The outlet should be rated at least 20A. Turn on the AC and wait for the temperature to drop. Then, monitoring the voltage on the generator’s panel (there can be a display, a voltmeter, LED lights), you can add the power to the AC or turn on other devices you need, one by one.
Remember to refuel your generator before the tank gets fully drained. At the constant work, it’s also crucial to replace the oil timely.
