8. Troubleshooting

8.1 Common Issues and Solutions

Controller Damage from Reverse Battery Connection: If the battery is connected with incorrect polarity, the controller may be damaged. Always ensure correct positive (+) and negative (-) connections. The unique reverse connection protection circuit is designed to mitigate this, but extreme cases or prolonged incorrect connection can still cause issues.
Brake Activation: The controller will activate the brake under two primary conditions:
- If the wind speed is too high, or if the controller loses connection to the wind turbine, it will activate the brake to limit the charge circuit and protect the system.
- When the battery is fully charged and no longer requires charging, the controller will also activate the brake.
Releasing the Brake: If the brake is active and you need to release it (e.g., after troubleshooting or system adjustment), disconnect all cables from the controller, then reconnect them in the correct order (battery first, then wind turbine). The brake will be released automatically.

9. User Tips

Battery Compatibility: This controller is specifically designed for Lead-acid and GEL batteries. Ensure your battery type is compatible for optimal performance and longevity.
MPPT Functionality: The MPPT060 controller's MPPT function is particularly beneficial in low wind speed conditions (e.g., 5-8 m/s). It boosts the charge voltage to meet the battery's charging requirements, significantly increasing power efficiency compared to controllers without this feature.
Recommended Wind Turbine Power: To extend the controller's service life, adhere to recommended power limits:
- For 12V battery systems, connect a wind turbine with a rated power under 400W (especially if the wind turbine's top net weight exceeds 15kg).
- For 24V battery systems, a 0-600W wind turbine rated power is acceptable.

Q: How do I know if the MPPT060 has MPPT function?: A: The MPPT060 indeed has MPPT function. This is evident when, even at lower wind speeds (e.g., 5-8 m/s), the controller can output sufficient voltage to charge your battery. Without this function, a wind turbine might stop or run very slowly at the same wind speed, with minimal or no voltage output.
Q: What is the difference between WT060 and MPPT060?: A: The MPPT060 includes an MPPT function. This allows it to boost the charge voltage to meet the required charging voltage, especially under slow wind speeds, thereby increasing power efficiency. The WT060 model may not have this advanced feature.
Q: My wind turbine is DC output with 2 cables. How do I connect it to your controller?: A: The controller has three terminals for wind turbine connection. For a DC wind turbine with 2 cables, you can connect any two of these cables to any two of the three wind turbine input terminals on the controller.
Q: How long is the warranty?: A: The product comes with a 1-year warranty.
Q: What happens if I reverse the battery connection?: A: The controller may be damaged. Always ensure correct polarity when connecting the battery.
