Notes:
•
The solar charger can be installed in a positive or in a negative grounded system. In a vehicle
for example, always apply a short single ground connection, ideally close to the battery, to
avoid ground loops that could cause system instabilities.

•
When the optional battery temperature sensor is connected to the solar charger to enable
temperature compensated charging, please make sure that this sensor is located as close as
possible to the battery. When no temperature sensor is connected to the solar charger,
charge voltages will not be compensated against varying temperature.

The Expansion Port is intended for future use. Do not connect to any device.
