6 Application and functions in detail
If the solar modules have sufficient charging voltage, the solar charge regu-
lator allows the battery to be charged by up to 14.2 V.
As soon as these voltage is reached, the charging current is reduced to fully
charge the batteries without impairing them. If the charging voltage of the
solar modules is insufficient (e.g. in the dark), an integrated isolation diode
prevents the batteries from discharging.
Living area battery and starter battery are charged simultaneously. The living
area battery has priority.
7 Maintenance
The device requires no maintenance.
Clean the device with a soft, slightly damp cloth and mild detergent. Never
use spirit, thinners or similar substances. Do not allow liquids to enter the
device.
