5.2 Connection Procedure

It is strongly recommended to install air switches (breakers) between all DC and AC input/output components. Follow the sequence below to power on your system:

1. First, turn on the breaker between the battery and the controller.
2. Second, turn on the breaker between the wind turbine and the controller.
3. Third, turn on the breaker between the DC load and the controller.
4. Finally, turn on the breaker between the solar panels and the controller.

To shut down the system, please follow the reverse order.

5.3 Wind Turbine Connection

• For AC wind turbines, any of the three wires from the wind turbine can be connected to any wind terminal on your controller, as they are non-electrode.
• For DC wind turbines with 2 wires (Positive/Negative), you can connect them to any wind terminals on your controller.

5.4 Lightning Protection

It is highly recommended to install additional lightning protection for your power system to ensure safety and longevity of components.

6. Operating Instructions

The controller's large LCD screen provides real-time monitoring of voltage and current parameters for the wind turbine, solar panels, and connected loads. It also displays battery status and system mode.

6.1 LCD Display and Control

6.2 Charging Modes

• Wind Charging: Utilizes MPPT boost charging technology, which makes under low wind speed, the Wind turbine's electricity can still be used. In high wind speed or the Wind turbine of power is beyond the scope of the battery and load absorption, the controller immediately launched the step-less unloading function, protection system of the equipment.
• Solar Charging: Employs series MOS tube PWM technology, which makes the controller power consumption is small, the system more stable.

7. Maintenance

To ensure the longevity and reliable operation of your controller, the inner circuit board is sprayed to prevent dust, moisture, and static electricity. Regular visual inspections for dust buildup and ensuring proper ventilation are recommended. Keep the device clean and free from obstructions.

8. Troubleshooting

• Wind speed too fast: If the output voltage or current from the wind generator exceeds safe limits, the controller will automatically activate the brake and gradually slow down the turbine. Simultaneously, the dump load will consume excess current. In severe weather like hurricanes, it is strongly recommended to manually lower the wind turbine.
• Wind generator running slowly after connection: This can occur if the battery reaches its floating voltage, or if the rated output voltage of the wind generator is significantly higher than the battery voltage. The voltage is dragged by the battery, so the speed will be very low. Also, check for a burnt-out dump load MOS due to incorrect operation.
• Wind generator dump load with small current: The controller protects the entire system by detecting battery voltage, charging current, and temperature. When the battery reaches its float charge voltage or high temperature, the wind generator will dump load, regardless of the charging current.
• No charging current on LCD despite wind/solar activity: Charging only occurs when the input voltage of solar panels or the wind generator is higher than the battery voltage. Ensure the battery is properly connected and not already fully charged.
• LCD does not light up: The controller is powered by the battery or solar input. Check the battery connection to the controller. If the battery is damaged, replace it. Verify that the solar input is functional on a sunny day.

9. User Tips

• Hybrid System Advantage: While you can connect only a wind turbine or only solar panels, establishing a hybrid wind-solar system provides better charging reliability, especially for low-power consumption equipment like street lights and monitoring systems. Low-power wind turbines in residential areas often experience low wind speeds and shorter operating times, making solar a valuable complement.
• System Voltage Design: The system voltage is equivalent to the voltage of the battery pack. Once the battery voltage is designed, the input voltage from the wind turbine generator and solar modules must be matched according to the specifications in the parameter table. Therefore, users cannot simply think that a lower voltage design will result in a bigger charging current, ignoring that excessive current can exceed the working range of the controller or battery and cause damage.
