- Disconnect Power: Always disconnect all power sources (wind turbine, solar panels, battery) before installing or servicing the controller.
- Correct Polarity: Ensure all connections are made with correct polarity. Reverse polarity can severely damage the controller and connected components.
- No Short Circuits: Prevent short circuits between terminals. This is critical during wiring.
- Proper Grounding: Ensure the system is properly grounded according to local electrical codes.
- Ventilation: Install the controller in a well-ventilated area to allow for proper heat dissipation.
- Environmental Conditions: Avoid exposing the controller to direct sunlight, rain, excessive dust, or corrosive environments.
- Battery Safety: Batteries can produce explosive gases. Ensure adequate ventilation when working with batteries and avoid sparks or open flames. Wear appropriate personal protective equipment (PPE).
- Dump Load Connection: The external dump load resistor must be connected before connecting the wind turbine to prevent overvoltage.
5. Setup and Installation
Follow these steps carefully for proper installation of the hybrid charge controller. It is crucial to connect components in the specified order to prevent damage.

5.1 Wiring Diagram and Connection Order
Refer to the wiring diagram below for correct connections. The connection order is critical:
- Connect the Unloading Resistor (Dump Load): Connect the external dump load resistor to the "Unloading Resistor" terminals on the controller. This must be connected first.
- Connect the DC Load: If applicable, connect your DC loads to the "Load Terminal" on the controller.
- Connect the Battery: Connect the battery to the "Battery Terminal" (D+ and D-) on the controller. Ensure correct polarity. The controller will power on once the battery is connected.
- Connect the Solar Panels: Connect the solar panel array to the "Solar Panel Terminals" (S+ and S-) on the controller. Ensure correct polarity.
- Connect the Wind Turbine: Connect the wind turbine to the "Wind Turbines" terminals (U, V, W) on the controller.
Important: Always ensure no short circuits occur during wiring. Disconnect in reverse order: Wind Turbine, Solar Panels, Battery, DC Load, Unloading Resistor.
