The charger has the following safety devices:
▪
Input power limitation of the protection
When the solar panel capacity exceeds the nominal capacity, the
charger will reduce the capacity of the solar panel until below the
nominal capacity, in order to prevent excessively high currents
damaging the charger.
▪
Battery reversed polarity protection
If the battery was connected the wrong way around, the system
won’t work, in order to prevent that the charger gets damaged
or
becomes overheated.
▪
Photovoltaic input side too high voltage protection
If the voltage on the Solar panel input side is too high, the charger
will automatically interrupt the solar panel input.
▪
Photovoltaic input side short circuit
If the Solar panel input side is short-circuited, the charger will stop
charging. As the short-circuit is deactivated, charging will
automatically resume.
