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.
