Installation is easy. Simply connect the inverter’s output to your distribution circuits or electrical panel; connect your shore power cable (AC) to the inverter’s easy to reach terminal block; connect the batteries, and then switch on the power. Using the optional remote control, you can easily operate your inverter from anywhere within your motor coach.

There are two modes of operation associated with an inverter/charger:

Inverter Mode:

Direct current (DC) from the vehicle’s batteries is transformed into alternating current (AC) for use with you household electrical appliances.

Charger Mode:

Alternating current ( AC) is taken directly from shore power (or other AC sources) and passed directly to your household appliances . At the same time, the incoming AC is also converted to DC to recharge the vehicle’s batteries.
