5. Setup and Installation
Follow these steps for proper installation of your hybrid charge controller. Ensure all power sources are disconnected before making any connections.
- Mounting the Controller: Select a dry, cool, and well-ventilated location. Mount the controller securely using appropriate fasteners. Ensure adequate space around the unit for heat dissipation.
- Battery Connection: Connect the battery cables to the 'BATTERY' terminals on the controller. Ensure correct polarity (positive to positive, negative to negative). This connection should be made first.
- Solar Panel Connection: Connect the solar panel cables to the 'SOLAR INPUT' terminals. Verify correct polarity.
- Wind Turbine Connection: Connect the wind turbine cables to the 'WIND INPUT' terminals. Ensure proper phase connection for AC wind turbines or polarity for DC wind turbines.
- Load Output Connection (Optional): If using the load output feature, connect your DC loads to the 'OUT+' and 'OUT-' terminals. Observe polarity.
- Power On: Once all connections are secure, connect the battery bank. The controller display should illuminate. Then, connect the solar panels and wind turbine.
