Victron Energy Autotransformer

Autotransformer – Maximize Power in RV and Off-Grid Split-Phase Systems If you're running a 120/240V split-phase system in an RV or off-grid setup, you may not be using your full available power. This autotransformer is designed to balance split-phase loads, stabilize your system, and unlock full usable capacity— especially when running real-world 120V appliances that are rarely evenly distributed. The Real Issue in RV and Off-Grid Power Systems In a typical 30A split-phase system powered by a generator, inverter, or shore power source, 120V loads such as air conditioners, microwaves, and washers rarely stay balanced across both legs. When one leg becomes overloaded before the other, you hit system limits early even though unused capacity still remains. For example, one leg may be drawing 30A while the other is only drawing 10A. In that scenario, you are only using about 67% of your system’s total available capacity. What This
