ADDITIONAL INFO:
PROTECTION
Protection Instruction
PV over current
When the PV array's actual charging current or power exceeds
the controller's rated charging current or power, the controller
charges the battery as per the rated current or power.
PV short-circuit
protection
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.
PV reverse
polarity
protection
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.
Night reverse
charging
protection
Prevent the battery from discharging to the PV module at night.
Battery over
voltage
protection
When the battery voltage reaches the over voltage disconnect
voltage, the PV array will automatically stop charging the battery
to prevent the battery damage caused by overcharging.
Battery over
discharging
protection
When the battery voltage reaches the low voltage disconnect
voltage, the battery discharging is automatically stopped to
prevent battery damage caused by over discharging.
CAUTION
When a load is connected to the battery and the
load is connected to the controller's (Load) dry
contact, the battery over-discharge protection
takes eect.
Battery over
heating
protection
The controller detects the battery temperature through an
external temperature sensor. The battery stops working when
its temperature exceeds 65°C and resumes work when its
temperature is below 55°C.
Lithium battery
low temperature
protection
When the temperature detected by the optional temperature
sensor is lower than the Low Temperature Protection
Threshold(LTPT), the controller stops charging and discharging
automatically. When the detected temperature is higher than the
LTPT, the controller resumes work automatically. (The LTPT is
0 °C by default and can be set within the range of 10 ~ -40 °C.
Detail settings refer to the LTPT V1.0.)
