5.1 Protection
PV Over Current/power
When the charging current or power of the PV array exceeds the controller’s rated current or power, it will be charge at the
rated current or power.
WARNING: When the PV’s charging current is greater than the rated current, the PV’s open circuit voltage
cannot greater than the "maximum PV open-circuit voltage", otherwise the controller may be damaged.
PV Short Circuit
When not in PV charging state, the controller will not be damaged in case of a short-circuiting in the PV array.
WARNING: It is forbidden to short-circuit the PV array during charging. Otherwise, the controller may be
damaged.
PV Reverse Polarity
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.
CAUTION: When the PV array is connected reversely to the controller, and the PV array’s actual operating
power is greater than 1.5 times the rated charging power of the controller, the controller will be damaged.
Night Reverse Charging
Prevents the battery from discharging to the PV module at night.
Battery Reverse Polarity
Fully protected against battery reverse polarity; no damage will occur to the battery. Correct the miswire to resume normal
operation.
WARNING: Limited to the characteristic of lithium battery, when the PV connection is correct and battery
connection reversed, the controller will be damaged.。
Battery Over Voltage
When the battery voltage reaches the over voltage disconnect voltage, it will automatically stop battery charging to prevent
battery damage caused by over-charging.
Battery Over Discharge
When the battery voltage reaches the low voltage disconnect voltage, it will automatically stop battery discharging to prevent
