2. Setup and Installation
Proper installation is crucial for optimal performance and safety. Follow the connection order carefully.
2.1 Connection Order
Connect the system components in the following sequence:
- Battery: Connect the battery to the charge controller.
- PV Panel: Connect the solar PV panel to the charge controller.
- Load: Connect the DC load to the charge controller.
To disconnect the system, reverse the order: Load → PV Panel → Battery.
Figure 2.1: Diagram illustrating the correct connection order for the solar charge controller, battery, PV panel, and DC load.
2.2 No-Battery Mode and Battery Mode
The Tracer-AN G3 series supports operation with or without a battery, depending on the inverter type and power requirements.
Figure 2.2: Connection diagrams for operating the solar charge controller in no-battery mode (top) and battery mode (bottom).
No-Battery Mode Warning: When operating without a battery, ensure the inverter is connected directly to the controller's battery terminals. For high-frequency inverters, PV input power must be greater than (load output power ÷ inverter conversion efficiency ÷ controller conversion efficiency). For power frequency inverters, PV input power must be greater than (load output power ÷ inverter conversion efficiency ÷ controller conversion efficiency ÷ 2).
2.3 Temperature Sensor Connection
Connect the remote temperature sensor probe to the designated port on the controller. This ensures accurate temperature compensation for charging parameters, optimizing battery life.
