7.1 Protection
PV Short Circuit
PV Reverse Polarity
PV Over Current
The controller will limit charging power in rated charge power.
An over-sized PV array will not operate at maximum power point.
When not in PV charging state, the controller will not be damaged in
case of a short-circuiting in the PV array.
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.
Fully protection against battery reverse polarity, no damage to the
controller. Correct the connection to start normal operation.
If there are other energy sources to charge the battery, when the
battery voltage exceeds 15.8/31.3/62.3V, the controller will stop
charging to protect the battery from overcharging damage.
When battery voltage drops to the setting voltage of low voltage
disconnect ,the controller will turn off the load control relay1 to
protect the battery from over discharging damage.
Prevents the battery from discharging through the PV module at
night.
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 detects the internal temperature through internal
sensor, when the temperature exceeds the setting value, the
charging current will lower down followed by the decrease of
temperature, so as to control the controller's temperature rise, when
the internal temperature exceeds 85℃, the controller stops working
and restores after the temperature is below 75℃.
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.
