5. Setup and Installation
Follow these steps for proper installation of the Tracer2215BN solar charge controller:
- Mounting: Choose a suitable location for mounting the controller. It should be indoors, protected from direct sunlight, high temperatures, and water. Ensure adequate airflow around the heat sink. The mounting dimensions are 130mm x 204mm with a mounting hole size of Φ4.7mm.
- Wiring Sequence: It is crucial to connect the components in the correct order to prevent damage.
- Connect the battery to the controller first.
- Connect the solar panel to the controller second.
- Connect the DC load to the controller last.
- Disconnection Sequence: To disconnect the system, follow the reverse order: disconnect the load, then the solar panel, and finally the battery.
- Cable Sizing: Use appropriate cable sizes. For the Tracer2215BN, the recommended power cable size is 8AWG (10mm²).
- Polarity: Always ensure correct polarity for all connections (positive to positive, negative to negative). Reverse polarity can damage the controller.
