5. Setup and Installation
Proper installation is crucial for the safe and efficient operation of the hybrid charge controller. Follow these steps carefully.
5.1. Unpacking and Inspection
Upon receiving the product, carefully unpack all components and inspect for any shipping damage. The packing list includes:
- 1 x Wind Solar Hybrid Charge Controller
- 1 x External Discharge Resistor
- 2 x Connection Cables
- 1 x User Manual (this document)
Image: Contents of the product package, including the controller, dump load, connection cables, and user manual.
5.2. Mounting Location
Choose a mounting location that is:
- Dry and protected from direct weather exposure.
- Well-ventilated to ensure proper heat dissipation.
- Accessible for wiring and maintenance.
- Close to the battery bank to minimize voltage drop.
5.3. Wiring Connection Sequence
CRITICAL: Follow the connection sequence precisely to prevent damage to the controller or other components.
- Connect the Battery: First, connect the battery to the controller's battery terminals. Ensure correct polarity (+ to + and - to -). The controller will power on.
- Connect the Wind Turbine: Next, connect the wind turbine output to the controller's wind input terminals.
- Connect the Solar Panels: Then, connect the solar panel array to the controller's solar input terminals. Ensure correct polarity.
- Connect the Dump Load: Connect the external discharge resistor (dump load) to the designated dump load terminals. This is essential for excess energy dissipation from the wind turbine.
- Connect the DC Load (Optional): If using a DC load directly from the controller, connect it to the load output terminals.
Disconnection Sequence: To disconnect the system, follow the reverse order: DC Load, Dump Load, Solar Panels, Wind Turbine, then Battery.

6. Operating Instructions
Once installed, the controller will automatically begin charging. Use the LCD display and buttons to monitor and configure settings.
6.1. LCD Display Navigation
The LCD displays real-time system information. Use the buttons to navigate through menus and adjust parameters:
- OK Button: Enters menu, confirms selection, or cycles through main display screens.
- Up/Down Buttons: Navigates through menu options or adjusts values.
- Esc Button: Exits current menu or cancels an operation.
Commonly displayed parameters include battery voltage, charging current (wind/solar), total power generated, load status, and controller temperature.
6.2. Load Working Modes
The controller offers several load working modes for managing the connected DC load:
- Pure Light Control Mode: The load turns on automatically at dusk and turns off at dawn.
- Normally Open Mode: The load remains continuously on, regardless of light conditions.
- Light Control + Time Control Mode: The load turns on at dusk and remains on for a user-defined duration (up to four time periods) or until morning light.
Refer to the controller's menu for specific instructions on how to select and configure these load modes.
6.3. Battery Type Selection
It is essential to select the correct battery type in the controller settings to ensure optimal charging and prolong battery life. The controller supports various battery types, including lead-acid and lithium batteries. Use the Bluetooth APP or the controller's menu to configure this setting.
