H-Tronic SL 12/24-8 Manual page 16

– The operation under adverse conditions such as surrounding temperatures
over 50°C, inflammable gases, fumes, solvents, humidity above 80% and
dampness is not allowed under all circumstances.
– The device may only be used indoors, in a dry, sealed environment.
– If a safe operation is no longer possible, the device may not be installed
and must be secured against accidental operation. An unsafe operation can
be assumed if the unit is visibly damaged, if damaged during transport or if
stored under unfavorable conditions.
– If the overcharge protection fails, an explosive gas (oxyhydrogen) can occur
in the vicinity of the battery. It is therefore important to make sure that the bat-
tery is installed only in well-aerated rooms. If gel-lead batteries are charged,
the gas protection needs to be deactivated (see preferences).
– Only solar cells may be used as a power source.
– Please follow the sequence of attaching the wires. To detach the device use
the inverted sequence.
– In order to avoid short circuits between controller and battery, a fuse should
be installed to the positive terminal.
– If a connected device cannot be detached from a power source by e.g. a
blown fuse, it is recommended to attach it directly to the battery with the use
of a fuse.
Usually lead acid batteries are used with photovoltaic solar systems. Lead-acid
batteries must be protected from deep discharge and overcharging. This solar
controller fulfils both requirements. The solar battery charger will adapt to a 12V
or 24V system due to its automatic 12/24V recognition.
3. FunctionS
The solar charge controller monitors the battery charge level and controls the
charging process and the connection and disconnection of the attached con-
sumer. The battery is therefore ideally utilized and the life span will extend
considerably.
The following protective functions are basic functions of the controller:
Overcharge protection, deep discharge protection, protection against under-
voltage, protection against reverse current into the solar module.
