4. Setup and Installation
4.1 Mounting the Controller
Mount the Wanderer PG controller vertically on a flat, non-flammable surface in a well-ventilated indoor area. Ensure there is adequate clearance around the controller for heat dissipation. Avoid direct sunlight, high temperatures, and water exposure.
4.2 Wiring Connections
Follow the wiring sequence carefully to prevent damage to the controller or other components. The recommended wire gauge for the 10A model is 10-12 AWG.
- Connect the Battery: Connect the positive and negative terminals of the battery to the corresponding battery terminals on the charge controller. The LCD will illuminate if the connection is successful.
- Connect the Solar Panel: Connect the positive and negative terminals of the solar panel to the corresponding solar panel terminals on the charge controller.
- Connect the Load (Optional): Connect the positive and negative terminals of your DC load to the corresponding load terminals on the charge controller.
Disconnection Sequence: To disconnect the system, follow the reverse order: Load > Solar Panel > Battery.
