4. Setup and Wiring
Proper wiring is crucial for the safe and efficient operation of your solar charge controller. Follow these steps carefully. Always ensure all power sources are disconnected before making any connections.
Wiring Sequence:
- Connect the Battery: First, connect the battery to the charge controller. Ensure correct polarity (positive to positive, negative to negative).
- Connect the PV Array: Next, connect the solar panel (PV) array to the charge controller. Ensure correct polarity.
- Connect the DC Load (Optional): Finally, connect any DC loads to the designated load terminals on the controller.
Important: Connect the system in the order of 1) battery, 2) load, 3) PV array. Disconnect the system in the reverse order (PV array, load, battery).

Battery Type Selection and Calibration:
The controller is compatible with multiple battery types. To select or calibrate the battery voltage:
- Long press the BAT/▲ key to enter the setting program.
- Use the BAT/▲ and DC/▼ keys to toggle through the battery type options (e.g., Sealed, Gel, Flooded, LiFePO4, Lithium-Ion).
- Press the SET/⚙ key to save and confirm your selection.
- If you select "User-defined" battery type, you can proceed with setting specific parameters like absorption voltage, float voltage, and low voltage cutoff.
If there is a discrepancy between the battery voltage monitored by the controller and the value measured by a multimeter, you can calibrate the battery voltage using this setting.

6. Maintenance
To ensure the longevity and optimal performance of your Temank MPPT Solar Charge Controller, regular maintenance is recommended:
- Periodically inspect all wiring connections to ensure they are secure and free from corrosion.
- Keep the controller clean and free from dust and debris. Use a dry cloth for cleaning.
- Ensure adequate ventilation around the controller to facilitate proper heat dissipation.
- Monitor the LCD display for any fault codes or unusual readings.
7. Troubleshooting
The LCD display provides fault codes to help diagnose issues. Refer to the table below for common fault codes and their solutions:
| Fault Code | Fault Cause | Solution |
|---|---|---|
| 18 | Input photovoltaic voltage too low | Increase the number of solar panels or connect them in series to raise the photovoltaic input voltage. |
| 60 | Overtemperature protection | Allow the equipment to cool to below the recovery temperature to resume normal charging and discharging. |
| 63 | Battery voltage too high | Measure to confirm if battery voltage exceeds rated voltage and disconnect photovoltaic array circuit breaker. |
| 65 | Battery voltage too low | Charge the battery until voltage exceeds the undervoltage recovery point. Refer to '3.7 Default Parameters for Different Battery Types' for specific details. |
| 71 | Input photovoltaic voltage too high | Reduce the number of photovoltaic arrays connected to the controller to lower photovoltaic input; or adjust series and parallel connections to reduce voltage or current values. |
| 73 | Overcharging current | Reduce output terminal load to ensure total load is within rated limits of the controller and battery. |
| 72 | Overdischarging current | Reduce output terminal load to ensure total load is within rated limits of the controller and battery. |
