4)Time Control
Control the load on/off time by setting a real-time clock.
6 Protections
PV over current
When the charging power of the PV array exceeds its rated charging power, it will be
charged at the rated charging power.
PV short circuit
The controller will stop charging when the input terminal of the PV array is short-
circuited. After clearing the faults, the charging will resume automatically.
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.
Battery reverse polarity
When the polarity of the battery is reversed, the controller may not be damaged and
can continue to operate normally after the polarity is corrected.
Battery over voltage
When the battery voltage reaches the over voltage disconnect voltage, the controller
will automatically stop charging the battery to prevent battery damage caused by over-
charging.
Battery over discharge
When the battery voltage reaches the low voltage disconnect voltage, the controller will
automatically stop discharging the battery to prevent battery damage caused by over-
discharging. (Any controller connected loads will be disconnected. Loads directly
connected to the battery will not be affected and may continue to discharge the
battery.)
Battery over temperature
The controller detects the battery temperature through an external temperature sensor.
The battery will stop working when its temperature exceeds 65 °C and resume when its
temperature is below 55 °C.
Overload
When the load current is higher than 1.05 times the rated discharge current, the
controller will automatically cut off the output. After the load reconnects automatically
five times (delay of 5s, 10s, 15s, 20s, 25s), please reduce the electrical equipment. And
then press the load ON/OFF button or restart the controller or wait for one night-day
cycle (night time > 3 hours) to eliminate the overload fault.
Load short circuit
When the load is short-circuited (The short circuit current is higher than or equal to 2
times the rated discharge current), the controller will automatically cut off the output.
After the load reconnects automatically five times (delay of 5s, 10s, 15s, 20s, 25s),
please press the load ON/OFF button, or restart the controller, or wait for one night-day
cycle (night time > 3 hours). Then the load reconnection automatically will resume.

Controller over temperature
An internal temperature sensor can detect the internal temperature of the controller.
The controller stops working when its internal temperature exceeds 85 °C and resumes
when the internal temperature is below 75 °C.
TVS high voltage transients
The internal circuitry of the controller is designed with Transient Voltage Suppressors
(TVS), which can only protect against the 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.
7 Troubleshooting
Faults
When there is sufficient
direct sunlight on the PV
array, the charging indicator
does not light up.
The wire connection is
correct, but the controller is
not working.
