- Choose a dry, well-ventilated location, protected from direct sunlight, high temperatures, and moisture.
- Ensure there is sufficient air circulation around the controller for heat dissipation.
- Mount the controller vertically on a wall or flat surface using the provided mounting holes (refer to Figure 4.2 for dimensions).
5.2 Wiring Sequence
Important: Always connect in the following order to prevent damage:
- Connect the Battery: Connect the battery to the controller's battery terminals (positive to positive, negative to negative). The controller will power on.
- Connect the Solar Panel: Connect the solar panel to the controller's PV terminals (positive to positive, negative to negative).
- Connect the DC Load: Connect the DC load to the controller's load terminals (positive to positive, negative to negative).
To disconnect, follow the reverse order: load, then solar panel, then battery.
5.3 System Wiring Diagrams
The Tracer AN G3 supports various system configurations. Below are general wiring principles. For detailed diagrams, refer to the full product manual or consult a qualified installer.
