Intended use
The Solar Battery Charger is used to charge 12 V lead bat-
teries consisting of 6 individual parts (e.g. car battery) with
a capacity of
30 – 75 Ah.
The device has been developed
for connecting solar modules. Only suitable modules may
be used, e.g. Truma SM 23. Please pay attention to the max-
imum voltage and power consumption values. The preferred
usage area for the battery charger is batteries with gel, AGM
or liquid electrolyte.
The device is intended for interior installation.
If the device is being connected to the power supply using
motor vehicle cable harnesses, e.g. those of a tractor vehicle,
it must always be ensured that a type-approved interface is
used.
Use for incorrect purpose
The device is not suitable for charging:
– 6 V batteries or 6 V lead batteries,
– non-rechargeable batteries,
– nickel-cadmium batteries, for example.
If batteries with a nominal voltage of 6 V are charged using
this device, gassing will start immediately.
Explosive detonating gas will occur.
The device is only suitable for controlling solar modules. Do
not connect any other voltage sources (e.g. 230 V mains
voltage) to the device. This can lead to destruction of the
device and / or the sources. If other voltage sources are going
to be used with the device, please consult your dealer.
Battery care
(including maintenance-free batteries)
In order to achieve a long battery service life, attention must
be paid to the following points:
– Batteries should be fully charged before and after removing
power.
– During long periods of inactivity (no sun) the battery must
be disconnected and charged for 24 hours at least every
12 weeks.
In winter, store fully charged battery in a cool and frost-free
place and recharge at regular intervals (every 12 weeks).
