C.1.1 The Inverter

The sinewave-inverter section of your Combi generates a sinewave AC voltage with an exceptionally precise voltage and stabilized frequency, In order to start large electric motors, the user has the possibility to employ a short-start-power which is 3-times the nominal power of the Combi

The inverter is protected against overload and short-circuit. A power-stage with the latest MOS-FET power transistors, a toroidal transformer, and a fast regulating system make-up a robust and reliable inverter with very high efficiency. A load detection system serves to provide the smallest energy consumption and ensures a long life for the battery.

C.1.2 The Bypass switch

This unit can be connected to an AC input source. For example a stand-by motor generator or the AC grid, such as shore power or a caravan park. With the transfer system, on one side you have AC voltage which is used to run the load, on the other side the batteries are being charged. The distribution of energy between the AC loads and battery charger is automatic.
