2 Introduction
The XP-COMPACT is a sine wave inverter with integrated battery charger and solar charge con-
troller with many additional functions, it has been developed to be used as stand-alone (no grid
feeding) AC provider, or as continuous / break-free current supply provider (UPS).
2.1 Principle
schematic
Note:
(1) The neutral of the appliance is not connected to the earth whatever the functioning mode
is. If requested and according to the local regulation, an automatic connection between Neutral and
earth in inverter mode only may be done by installing a bridge internally to the unit. Please contact
your installer regarding this point.
2.2 Description of main functions
2.2.1 The
inverter
The sine wave inverter built in the XP-COMPACT generates a sinusoidal AC voltage with an ex-
ceptionally 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 XP-
COMPACT.
The inverter is protected against overload and short-circuits. 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 highest efficiency. A 1-20 Watt adjustable charge detection system serves to
provide the smallest energy consumption and ensures a long life for the battery.
2.2.2 The transfer system
XP-COMPACT can be connected to an AC source, for example a stand-by emergency generator
or the AC network. With the transfer system, on one side you have an alternating voltage at the
output for use by the connected consumer appliances. On the other side the batteries are charged.
The distribution of energy between the consumer appliances and battery charger is automatic.
