5. Configuració i instal·lació
Proper installation is crucial for the safe and efficient operation of your hybrid system. Follow these steps carefully.
Ubicació de la instal·lació:
- Mount the controller vertically on a non-flammable surface.
- Ensure adequate clearance around the controller for proper heat dissipation.
- Protect the controller from direct sunlight, rain, and excessive dust.
Seqüència de cablejat:
ADVERTIMENT: Incorrect wiring order can damage the controller and other components. Always connect in the specified sequence.
- Connect the Dump Load: First, connect the external unloading resistor (dump load) to the designated terminals (U, V, W). This is critical for wind turbine safety.
- Connecteu la bateria: Connect the battery bank to the controller's battery terminals (B+, B-). Ensure correct polarity. The controller will automatically detect 12V or 24V.
- Connecteu els panells solars: Connect the solar panel array to the solar input terminals (S+, S-). Observe correct polarity.
- Connect the Wind Turbine: Connect the wind turbine to the wind input terminals (D+, D-).
- Connect DC Loads (Optional): If using DC loads, connect them to the load output terminals (L+, L-).
After all connections are made, the controller's LCD screen should power on and display system parameters.
