Operation

The device is equipped with modern pulse width modulated
three-phase charging technology. This technology makes it
possible to have high power with light weight and compact
dimensions. It uses high-quality electronics to achieve a high
degree of efficiency. Automatic charging takes place in a pro-
tective way without damaging the batteries by overcharging
them. This increases the service life of the batteries consid-
erably. The device is suitable for batteries with liquid, gel or
AGM technology The charging procedure is adapted automat-
ically using an internal temperature sensor.
The device is designed for continuous and parallel operation.
Consumers can remain permanently connected or can be
switched on / switched off. Consumers are supplied and the
battery is charged at the same time. The consumer current
should be less than the solar charging current when this takes
place, otherwise the batteries will not be charged.
The optional consumer outlet can be enabled using the but-
ton. This is only used to connect small consumers to the bat-
tery charger, such as a lamp.
Please pay attention to the maximum voltage and power con-
sumption values.
