protection
When the actual PV array's charging current or power is higher than the
controller's rated charging current or power, the controller will charge the
battery per the rated current or power.
When not in the PV charging state, the controller will not be damaged in the
case of short-circuiting in the PV array.
WARNING: It is forbidden to short-circuit the PV array during charging.
Otherwise, the controller may be damaged.
When the PV array's polarity is reversed, the controller may not be damaged
and resume work after the mis-wiring is corrected.
CAUTION: If the PV array is reversed and its actual power is 1.5 times
the controller's rated power, the controller may be damaged.
Avoid the battery from discharging to the PV module at night.
When the polarity of the battery is reversed, the controller may not be
damaged and resume normal operation after the mis-wiring is corrected.
CAUTION: Limited to the characteristic of lithium battery, when the PV
array connection right and battery connection reversed, the controller will be
damaged.
When the battery voltage reaches the over voltage disconnect voltage, the
PV array will automatically stop charging the battery to avoid battery
damage.
When the battery voltage is lower than the low voltage disconnect voltage,
the battery discharging is automatically stopped.
The controller detects the battery temperature through an external
temperature sensor. The battery stops working when its temperature goes
higher than 65℃ and resumes work when its temperature is below 55℃.
When the temperature detected by the optional temperature sensor is lower
than the Low-Temperature Protection Threshold(LTPT), the controller will
stop charging and discharging automatically. When the detected
temperature is higher than the LTPT, the controller will be working
