The Autotransformer: for step up, step down and split phase balancing

An autotransformer can be used for step up, step down and split phase output balancing purposes. While the step up and step down functions are fairly straightforward, split phase output balancing may require some more attention.

Ground relay for use with Multi or Quattro Inverter/Chargers included
When operating in inverter mode, the neutral output of the inverter/charger must be connected to ground to guarantee proper functioning of a GFCI. In case of a split phase supply the neutral must be grounded. For this purpose a grounding relay is built in the autotransformer’s enclosure. The relay is controlled by the 230/240V Multi or Quattro. (The internal grounding relay in the 230/240V Multi or Quattro must be disabled).

Temperature protected
In case of overheating, the Autotransformer is disconnected from the supply. Reset is manual.

An alternative to stacked inverters
The alternative to stacking two 120V inverters to provide a 120/240V split phase supply is a 240V inverter with
an additional Autotransformer.
