Technichal Data - H-tronic SOLARLADEREGLER SL 12/24-8 Bedienungsanleitung

To keep the voltage drop and the heat development in the cable low, a 2.5 –
4 mm gauge wire is recommended. An additional fuse is not needed when
short circuit proof cables are used. If not, a fuse should be added to the positive
terminal of the battery to prevent a short circuit in the cable. Both components
must be installed in the same room with a small distance in between them.
2 Connecting the solar module
Make absolutely sure that the solar module is protected from light and not
producing any current (this can be achieved by fully covering it or connecting
it after sunset). Make sure that the solar module does not exceed the maximum
input power of the solar battery charger. First the solar module connection ca-
ble „+" is connected to the „+" of the left triple terminal (left of the solar charge
controller with the solar panel symbol). Then the negative lead „–" is connected
to the middle connector of the same triple terminal. Only now may the cover be
removed from the solar module.
3 Connecting a consumer
First, connect the „+" of the consumer to the middle connector of the terminal
block on the right of the solar charge controller (with the lamp symbol). Then
connect the negative cable „–" to the right connector of that same terminal
block. The pin assignment can be seen with the symbols on the controller or
from the picture in the manual.
NOTE!
Please make sure that consumers, that should not be turned off by the protection
system of the solar battery charger, (i.e. emergency lights or radio links), should
be connected directly to the battery.
Consumers with larger power consumption, (larger than the current output of the
charge controller) should be connected directly to the battery. In these cases,
the deep discharge protection of the solar battery charger does not function. In
addition, the consumers must be separately protected accordingly.
20 SOLAR CHARGE CONTROLLER
The system is not working. Possible causes:
– Reverse polarity of the battery: melted fuse; replace fuse with the same
type.
– Incorrect polarity of modules: avoid this under all circumstances.
– Switched polarity of the consumer: the consumers can be destroyed before
the fuse is triggered. Batteries hold large quantities of energy. If short circui-
ted, this energy is released in a short time. This can lead to immense heat
and thus can cause a fire at the point of the short circuit and explosion of
the battery.
