AutotransformerVictron Energy's Autotransformer can step up voltages from 120V to 240V, or step down from 240V to 120V. This enables the use of Victon's range of 240V only inverters to be utilized in 120 240V North American systems. It creates 120 Volts out of the 240 Volt input and generates the Neutral at the Auto Transformer. Many 120 240V inverters are actually two 120V inverters in the same box and are limited to half the rated full power on each leg. In
