Solar Charge Controller
Safety Information
- Read all the instructions in the manual before installation.
- DO NOT disassemble or attempt to repair the controller.
- Install an external fast-acting fuse or breaker as required.
- Disconnect the solar module and fast-acting fuses/breakers near the batterybefore installing or moving the controller.
- Power connections must remain tight to avoid excessive heating from a loose connection.
- Only charge batteries that comply with the controller’s parameters.
- The battery connection may be a single battery or a bank of batteries.
- Risk of electric shock! The PV and load can produce high voltages when thecontroller is working.

Wiring
Connect the system in the order of ❶battery 
loadPV array following Figure 2-2,” Schematic Wiring Diagram,” and disconnect the system in the reverse order❸❷❶.
NOTE: Do not connect the circuit breaker or fast-acting fuse while wiring the controller. Ensure that the leads of “+” and “-” poles are connected correctly. NOTE: A fast-acting fuse whose current is 1.25 to 2 times the controller’s rated current must be installed on the battery side with a distance from the battery not greater than 150 mm. WARNING: The controller has no PV reverse connection protection; please connect it correctly.

② “○” states LED indicator on; “×” states LED indicator off.
Operating
- Load ON/OFF Setting Press the button to control the load output when the controller is powered on.
- Battery Type Setting
Operation:
Step 1: Enter the setting mode by pressing the button for 5s until the battery status LEDs are flashing.
Step 2: Select the desired mode by pressing the button.
Step 3: The mode is saved automatically without any operation for 5S, and the LED stops flashing. Battery Type Indicator shows as below:
| LED1 | LED2 | LED3 | Battery type |
| 0 | X | X | Sealed(Default) |
| 0 | 0 | X | Gel |
| 0 | 0 | 0 | Flooded |
NOTE: “○” states LED indicator on “×” states LED indicator off

Protection
- Battery Over Voltage Protection
When the battery voltage reaches the Over Voltage Disconnect Voltage(OVD), the controller stops charging the battery to protect the battery from being overcharged. - Battery Over Discharge Protection
When the battery voltage reaches the Low Voltage Disconnect Voltage(LVD), the controller stops discharging the battery to protect the battery from being over-discharged. - Overload Protection
The load is switched off after a delay when the load current exceeds 1.25 times the rated current. The user must reduce the load appliance, press the button, or restart the controller. - Load Short Circuit Protection
The load is switched off when the load short circuit (≥3 times the rated current) happens. The user must clear the short circuit faults, press the button, or restart the controller. - High Voltage Transients Protection
The controller is protected against small high voltage transients. In lightning-prone areas, an external lightning arrester is recommended.
Troubleshooting
| Faults | Possible reasons | Troubleshooting |
| The charging LED turns off during the daytime when sunshine falls on PV modules properly. | PV array disconnection | Confirm that PV and battery wire connections are correct and tight. |
| No LED indicator | Battery voltage may be less than 8V | Measure battery voltage with the multi-meter. Min.8V can start up the controller. |
| Charging LED fast flashes. | Battery over voltage | Check if the battery voltage is higher than the OVD, and disconnect the PV. |
| LED1 fast flashes. | Battery over-discharged | The load will recover when the battery voltage is restored to or above the LVR (low voltage reconnect voltage). |
| Load LED flashesslowly. | Overload* | 0 Please reduce the number of electric equipment. C) Press the button or restart the controller. |
| Load LED fastflashes. | Load short circuit | (i) Check carefully loads connection, clear the fault. ® Press the button or restart the controller. |
* When the load current exceeds 1.25 times, 1.5 times, and 2 times the rated value, the controller can automatically turn off loads after 60s, 5s, and 1s, respectively.
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 exceeds the controller’s rated value.
- User disassembly or attempted to repair the controller without permission.
- The controller is damaged due to natural elements such as lighting.
- The controller is damaged during transportation and shipment.
