5.2 Connection Steps
- Connect the Battery: Connect the positive and negative terminals of your battery bank to the B+ and B- terminals on the controller. Ensure correct polarity. The controller will automatically detect the system voltage (12V or 24V).
- Connect the Solar Panels: Connect the positive and negative output from your solar panels to the S+ and S- terminals on the controller. Observe correct polarity.
- Connect the Wind Turbine: Connect the three-phase output from your wind turbine to the U, V, and W terminals on the controller. The order of connection for U, V, W does not affect operation.
- Connect the Dump Load: Connect the external dump load resistor to the L+ and L- terminals. This resistor dissipates excess energy when the battery is full or during high wind conditions to protect the system.
- Connect the DC Load (Optional): If you have a DC load, connect it to the D+ and D- terminals. Ensure the load's voltage matches the system voltage.
Important: Always connect the battery first, then solar, then wind, and finally the load. Disconnect in the reverse order.
6. Operating Instructions
The controller features an LCD display and four buttons for monitoring and configuration.

7. Maintenance
Regular maintenance ensures optimal performance and longevity of your controller.
- Cleaning: Periodically clean the controller's exterior with a dry, soft cloth. Do not use liquids or abrasive cleaners.
- Connection Checks: Annually inspect all wiring connections for tightness and corrosion. Loose connections can cause power loss or overheating.
- Ventilation: Ensure the controller's ventilation fins are free from dust and debris to maintain proper heat dissipation.
- Environmental Conditions: Verify that the installation environment remains within the recommended temperature and humidity ranges.
8. Troubleshooting
This section addresses common issues you might encounter with your Mars Rock Wind Solar Hybrid Controller.
- No Power Display:
Possible Cause: Battery not connected or low voltage.
Solution: Check battery connections and ensure battery voltage is above the minimum operating threshold. - No Charging from Solar/Wind:
Possible Cause: Solar panels or wind turbine not connected, faulty, or insufficient input.
Solution: Verify connections, check solar panel output and wind turbine rotation. Ensure environmental conditions (sunlight, wind) are adequate. - Battery Not Fully Charging:
Possible Cause: Incorrect battery type setting, undersized solar/wind input, or excessive load.
Solution: Verify battery type setting in the controller. Ensure total input power from solar and wind matches system requirements. Reduce load if necessary. - Controller Overheating:
Possible Cause: Poor ventilation, excessive load, or internal fault.
Solution: Ensure adequate airflow around the controller. Reduce load. If overheating persists, disconnect power and contact support. - Dump Load Constantly Active:
Possible Cause: Battery full, or overvoltage condition.
Solution: This is normal operation if the battery is fully charged and there is excess power. If it occurs prematurely, check battery voltage settings and ensure the battery is accepting charge.
