When the charging current of the PV array exceeds the
controller's rated current, it will be charged at the rated
current.
When the voltage of PV will exceed 50V, the controller will
stop charging and restart to charge when the PV voltage is
below 45V
When the PV voltage is below 50V and short circuit, the
controller will stop charging; the controller restart to charge
when the fault is cleared, it doesn't damage the controller.
When the polarity of the PV array is reversed, the
controller may not be damaged and can continue to
operate normally after the polarity is corrected.
Prevents the battery from discharging to the PV module at
night.
Fully protected against battery reverse polarity; no damage
will occur to the battery. Correct the wiring error to resume
normal operation.
When the battery voltage reaches the overvoltage
disconnect voltage, it will automatically stop battery
charging
to
prevent
over-charging.
The controller can detect the battery temperature through
an external temperature sensor. The controller stops
working when its temperature exceeds 65 ° C and restart to
work when its temperature is below 55 ° C.
The controller is able to detect the temperature inside the
battery. The controller stops working when its temperature
exceeds 85 ° C and restart to work when its temperature is
below 75 ° C.
The internal circuitry of the controller is designed with
Transient Voltage Suppressors (TVS) which can only
protect against high-voltage surge pulses with less energy.
If the controller is to be used in an area with frequent
lightning strikes, it is recommended to install an external
surge arrester.
