圖 3.2：典型系統接線圖
This diagram illustrates a typical solar power system setup, showing the connection of the solar panel to the controller, the controller to the battery, and the controller to various DC and AC loads via an inverter. Ensure correct polarity for all connections.
The connection order is critical:
- 連接電池： First, connect the battery to the controller's battery terminals. Ensure correct polarity (positive to positive, negative to negative). The controller will automatically detect the system voltage (12V/24V). The controller supports Lead-acid Batteries (Sealed, AGM, Gel, Flooded) and User-defined settings.
- 連接負載： Next, connect your DC loads to the controller's load terminals.
- Connect the Solar Panel (PV): Finally, connect the solar panel array to the controller's PV terminals.
The disconnection order is the reverse: PV -> Load -> Battery.
