3.
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.
4.
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.
5.
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.
6.
Photovoltaic input reversed connection protection
In case the Solar panel is connected the wrong way around, the
charger will not become defective. As soon as the connection
problem is solved, normal functioning will resume.
7.
Overload protection
When the capacity of the load exceeds the nominal value, the
overload protection will be activated.
8.
Short-circuit of the load
When the load is short-circuited, the charger protection will
intervene. After a delay, the charger will attempt to activate the
load again. This protection can be operated to a maximum of 5
times per day.
9.
Reversed protection charging at night
This protective function prevents the battery from becoming
discharged via the solar panel during the night.
10.
Lightning protection
11.
Temperature protection
When the temperature of the charger is higher than the set value,
the charging current will be decreased or even stopped
altogether. See the following diagram:
