Installation Guide
Follow these steps for proper installation of your MPPT solar charge controller. Ensure all power sources are disconnected before beginning.
Wiring Sequence
- Connect the Battery: Always connect the battery to the controller first. Ensure correct polarity (positive to positive, negative to negative). The controller will automatically detect the system voltage (12V or 24V).
- Connect the Solar Panel: Connect the solar panel array to the PV terminals. Ensure correct polarity. The PV input voltage should not exceed 150V.
- Connect the DC Load (Optional): Connect your DC loads to the load terminals. Ensure correct polarity.
- Connect Remote Temperature Sensor (Optional): If using, connect the remote temperature sensor to its dedicated port and attach the sensor to the battery for accurate temperature compensation during charging.
- Connect Communication Cable (Optional): If using an MT-50 remote meter or PC software, connect the RS-485 communication cable.

Wiring Precautions
- Ensure all connections are tight to avoid loose contacts and excessive heat.
- Use appropriate wire gauges for all connections to handle the expected current.
- Always connect the battery first and disconnect it last during installation or uninstallation.
Operation
Once installed, the controller will begin operating automatically. The LED indicators provide a quick status overview:
- PV LED: Indicates solar panel input status.
- Battery LED: Shows battery charging status.
- Load LED: Indicates DC load output status.
Battery Type Settings
The controller supports various battery types. To optimize charging, it is crucial to set the correct battery type. This typically requires an external device like the MT-50 remote meter or PC software.
- Connect the MT-50 remote meter or PC to the controller via the RS-485 port.
- Access the "Control Parameter" menu.
- Select your battery type: Sealed, Gel, Flooded, or User-defined.
- For custom settings or Lithium (LiFePO4) batteries, select "User-defined" and adjust parameters according to your battery manufacturer's specifications.
The controller comes with pre-programmed settings for Sealed, Gel, and Flooded batteries. For these types, only Equalize and Boost times can be changed. For other adjustments, the "User-defined" mode is necessary.
Load Control
The load output can be controlled manually or automatically based on various settings (e.g., dusk-to-dawn, timer). These settings are configurable via the MT-50 remote meter or PC software.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your solar charge controller.
- Check Connections: Periodically inspect all wiring connections for tightness and corrosion. Tighten any loose connections.
- Clean the Controller: Keep the controller's heat sink and casing clean from dust and debris to ensure proper heat dissipation. Use a dry cloth for cleaning.
- Inspect Wiring: Check for any signs of wear, fraying, or damage to the cables. Replace damaged cables immediately.
- Monitor Performance: Regularly monitor the system's performance using the MT-50 remote meter or PC software to ensure stable operation and identify any anomalies.
- Battery Inspection: Follow the battery manufacturer's maintenance guidelines for your specific battery type.
Troubleshooting
If you encounter issues with your controller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No charging from PV | Solar panels not connected, incorrect polarity, insufficient sunlight, damaged panel/wiring. | Check PV connections and polarity. Ensure adequate sunlight. Inspect panels and wiring for damage. |
| Battery not charging | Battery not connected, incorrect polarity, battery voltage too low, incorrect battery type setting. | Verify battery connections and polarity. Check battery voltage. Ensure correct battery type is selected in settings. |
| Load not working | Load not connected, incorrect polarity, load overcurrent, battery voltage too low, load control settings. | Check load connections and polarity. Reduce load if overcurrent. Check battery voltage. Adjust load control settings. |
| Controller overheating | Poor ventilation, excessive current, high ambient temperature. | Ensure adequate airflow around the controller. Reduce load or PV input if consistently overheating. Relocate to a cooler area if possible. |
