Autotransformer for 240 VAC Applications (T240)
The T240 allows a single inverter to increase it’s output voltage from
120 volts to 240 volts or it will take 240 Vac from a generator and “step-
down” the voltage to 120 Vac for the single inverter. For step-up and step-
down functions, two T240s will be required. Using a T240
Autotransformer optimizes the generator output of smaller generators
(< 8 kW) and improves charging time.
Inverter Stacking Control – Series (ISC-S) Cable
The ISC-S cable is a special communications cable that allows two Sine
Wave Plus inverters to be connected together in “series” to provide power
to both 120 Vac loads and 240 Vac loads.
See the ISC-S Owner’s Guide for more information on stacked inverter
applications.
