5. Protections
PV Short Circuit
In case of a short circuit on the module the charging process will be
stopped automatically.
PV Reverse Polarity
Full protection from reverse polarity on modules and battery. Make sure
the wiring is done correctly to ensure a proper operation.
CAUTION: Risk of electric shock!
Battery Overvoltage
If the battery voltage exceeds a certain value the charging process is
stopped to keep the battery from being damaged.
Battery Undervoltage (risk of deep discharge)
If the battery voltage drops under a certain value the controller disconnects
from the battery to avoid deep discharge.
Battery Overheating
(External temperature sensor needed)
If the battery temperature exceeds 65°C the charging process is stopped
automatically. The controller proceeds after a cool down to 50°C.
Load Overload
If the load current is 1.05 times higher than the load output’s rated current
the load will be disconnected. In this case the load must be reduced and
the controller needs to be restarted. If the fault still occurs after 5 restarts
please reduce the load again and confirm via the SET button.
Restart the controller again or wait for the night-day-cycle (> 3hrs during
the night).
Load Output Short Circuit
In case of a load short circuit clear the fault and restart the controller.
Damaged Temperature Sensor
In case of a damaged temperature sensor the controller will proceed
charging with an estimated default temperature of 25°.
Charge Controller Overheating
If the charge controller exceeds a temperature of 85°C it shuts down
automatically and restarts after a cool down to 75°C.
