5. Configuració i instal·lació

Follow these steps for proper installation of your EPEVER TRIRON 3210N solar charge controller. Refer to Figure 5.1 for a visual representation of the system connections.

1. Muntatge del controlador: Choose a suitable location for mounting the controller. It should be in a dry, well-ventilated area, protected from direct sunlight and moisture. Ensure there is adequate space around the controller for air circulation and heat dissipation.
2. Connecteu la bateria: First, connect the battery to the controller's battery terminals (marked with a battery symbol). Ensure correct polarity: connect the battery's positive terminal to the controller's positive battery terminal, and the battery's negative terminal to the controller's negative battery terminal. The controller will power on once the battery is connected.
3. Connect the Solar Panels (PV Array): Next, connect the solar panels to the controller's PV terminals (marked with a solar panel symbol). Again, observe correct polarity: connect the solar panel's positive output to the controller's positive PV terminal, and the solar panel's negative output to the controller's negative PV terminal.
4. Connecteu la càrrega de CC (opcional): If you have DC loads, connect them to the controller's load terminals (marked with a light bulb symbol). Ensure correct polarity. The controller will manage power delivery to these loads.
5. Connect Optional Modules/Accessories: The TRIRON N series supports various optional modules such as display units (DB1, DSI), relay modules (RCM, RCS), and USB communication modules (USB1). These can be integrated into the modular slots on the controller. Refer to Figure 5.2 for examples of replaceable accessories.
6. Connecteu el sensor de temperatura (opcional): For accurate battery charging, connect the external temperature sensor to the designated port on the controller. This helps the controller adjust charging parameters based on ambient temperature.
7. Encès: Once all connections are secure and verified for correct polarity, you can close the circuit breakers or fuses for the battery and solar array. The controller's display will activate, showing system parameters.
