3. Configuració i instal·lació
Proper installation is crucial for the safe and efficient operation of your solar charge controller. Please follow these steps carefully.
3.1 System Diagram and Wiring
Refer to the system diagram above for a visual representation of the connections.
- Connecteu la bateria: Connect the battery to the battery terminals (4) on the controller. Ensure correct polarity (+ to + and - to -). It is highly recommended to install a fuse on the positive battery line.
- Connect the Load: Connect the DC load to the load terminals (5) on the controller. Ensure correct polarity. A fuse should also be installed on the positive load line.
- Connect the PV Array: Connect the solar panel (PV array) to the photovoltaic array terminals (3) on the controller. Ensure correct polarity. An appropriate breaker should be installed between the PV array and the controller.
- Connect Inverter (Optional): If using an inverter, connect it to the battery terminals or a separate distribution block connected to the battery, ensuring proper fusing and grounding. The diagram shows an inverter connected to the AC output, which implies it's an AC load, but typically inverters connect directly to the battery bank. For DC loads, connect to the load terminals.
- Sensor de temperatura (opcional): If using an external temperature sensor, connect it to the temperature sensor interface (2).
- Communication Interface (Optional): For remote monitoring or control, connect RS485/RJ45 cables to interface (6) or use the optional Bluetooth module.
Important Safety Note: Always connect the battery first, then the load, and finally the solar panel. Disconnect in the reverse order: solar panel, then load, then battery. Ensure all connections are tight and secure.
