3.2 Parameter Setting
- Browse PV Parameters: Press the "PV" button to view specific parameters of the PV array, such as voltage, current, and power.
- Modify Battery Type/Charging Parameters: When the display shows "battery type" or a voltage value (e.g., C13.6V), press and hold the "BAT/up" button until the value flashes. Then, use the "up" or "down" buttons to adjust the value. Press "SET" to confirm and save.
- Load Mode Setting: Press and hold the "DC" button until "load value" flashes. Use the "up" or "down" buttons to modify the setting. Press "SET" to save. Available load modes include:
- 00H: Load Turn Off
- 24H: Load always Turn On
- 01H-23H: Time Control (Set load On's duration)

4. Battery Charging Parameters
The controller supports multiple battery types including Sealed Lead-Acid, Flooded, Gel, and Lithium (LiFePO4). Customizable charging voltages are available for user-defined battery types.
| Battery Type | Boost Voltage | Float Voltage | Low Voltage Reconnect |
|---|---|---|---|
| Gel | 14.2V | 13.8V | 10V |
| Sealed | 14.4V | 13.8V | 10V |
| Flooded | 14.6V | 13.8V | 10V |
| Li (LiFePO4) | 14.4V | --- | 10V |
| User | 13.9-18V | 12.5-14.4V | 8-12.3V |
The controller features a 4-stage charging algorithm: Bulk Charge, Boost Charge, Float Charge, and Equalization, ensuring rapid, efficient, and safe battery charging.
5. Maintenance
The die-cast aluminum design of the controller ensures good heat dissipation, reducing noise and saving energy. Regularly check for clear ventilation around the heatsink to maintain optimal performance. Keep the unit free from dust and moisture.

6. Troubleshooting
The controller's self-diagnostic capability can assess and protect against various issues. Error codes are displayed on the LCD screen to help identify problems.
| Code | Description | How To Solve |
|---|---|---|
| 18 | Input PV voltage is low | Increase the PV voltage |
| 60 | Over-temperature protection | Fan will work and temperature reduction automatically |
| 63 | Battery voltage is high | Battery high voltage protection and wait for recovery |
| 65 | Battery voltage is low | Battery over-discharge and wait for recovery |
| 71 | Input PV voltage is high | Decrease the PV voltage |
| 73 | Over-charging current | Decrease the PV power |
The controller also includes full system protection against PV array short circuit, PV overcurrent, load overload, load short circuit, PV reverse polarity, battery reverse polarity, and over-temperature.
