CAUTION: Please refer to user guide or contact with the sales for the

detail of setting operation.

(2)Load Set Mode

1)Manual Control(default ON)

The load is turned ON/OFF via the button.

2)Light ON/OFF

3) Light ON/OFF + Timer

4)Time Control

Control the load on/off time through setting real-time clock.

6 Protections

 PV Over Current

When the charging power of the PV array exceeds its rated power, it will be charged at

the rated power.



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.



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

Fully protected against battery reverse polarity; no damage to the controller will result.

Correct the miswire to resume normal operation.

 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 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 Overheating

The controller can detect the battery temperature through an external temperature

sensor. The controller stops working when its temperature exceeds 65 ° C and begins

working when its temperature is below 55 ° C.



Load Overload

When the load is overloading (The overload current is ≥ 1.05 times the rated load

current), the controller will automatically cut off the output. If the load reconnects

automatically five times (delay of 5s, 10s, 15s, 20s, 25s), it needs to be cleared by

pressing the Load button restarting the controller, switching from Night to Day

(nighttime > 3 hours).



Load Short Circuit

When the load is short circuited (The short circuit current is ≥ 2 times the rated controller

load current), the controller will automatically cut off the output. If the load reconnects

the output automatically five times (delay of 5s, 10s, 15s, 20s, 25s), it needs to be

cleared by pressing the Load button, restarting the controller or switching from Night to

the Day (nighttime > 3 hours).



Controller Overheating

The controller is able to detect the temperature inside the battery through an optional

remote sensor. The controller stops working when its temperature exceeds 85 ° C and

begins to working when its 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 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.

9.Disclaimer

This warranty does not apply under the following conditions:

 Damage from improper use or use in an unsuitable environment.

 PV or load current, voltage or power exceeding the rated value of controller.

 The controller is working temperature exceed the limit working environment

temperature.

 User disassembly or attempted repair the controller without permission.

 The controller is damaged due to natural elements such as lighting.

 The controller is damaged during transportation and shipment.

Troubleshooting

Confirm that PV and battery wire

connections are correct and tight

Please check the voltage of battery. At

least 8V voltage to activate the

controller.

Check if battery voltage is higher than

OVD(over voltage disconnect voltage),

and disconnect the PV.

When the battery voltage is restored to

or above LVR(low voltage reconnect

voltage), the load will recover

The controller will automatically turn the

system off. But while the temperature

decline to be below 55 º C, the controller

will resume.

When heat sink of controller exceeds

85℃, the controller will automatically cut

input and output circuit. When the

temperature below 75℃,the controller

will resume to work.

①Please reduce the number of electric

equipments.

②Restart the controller.

③wait for one night-day cycle (night

time>3 hours).

①Check carefully loads connection, clear

the fault.

②Restart the controller.

③wait for one night-day cycle (night

time>3 hours).
