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 charged at the
rated current or power.
WARNING:
Whe
n the PV’s charging current is higher than the rated current, the PV’s open-circuit voltage
cannot be higher than the "maximum PV open-circuit voltage." Otherwise, the controller may be damaged.
PV Short Circuit
When not in a 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: The controller is damaged when the PV array is connected reversely to the controller, and the PV
array’s actual operating power exceeds 1.5 times the rated charging power.
Night Reverse Charging Prevents the battery from discharging to the PV module at night.
Battery Reverse Polarity
Fully protected against reverse battery polarity; no damage will occur to the battery. Correct the miswire to resume normal
operation.
WARNING: The controller, limited to the lithium battery characteristic, will be damaged when the PV connection
is correct and the battery connection is reversed.
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
