I own a Mercedes Sprinter with a Volta Power Systems 13.5kWh rig. It's being used for mobile sound recording. Wanna put a small 6000btu Mitsubishi MUZ-FH06NA in it, powered off the 120v supplied by the Volta batteries. Can I use the Victron autotransformer 120/240 32a? If not, what would be the best way to accomplish this?
