5. Configurazione e installazione

Follow these steps for proper installation of your charge controller:

1. Montaggio: Choose a dry, well-ventilated location for mounting the controller. Ensure there is sufficient clearance around the unit for heat dissipation. Mount vertically on a non-flammable surface.
2. Sequenza di cablaggio:
   • Connect the battery cables to the battery terminals on the charge controller. Ensure correct polarity (+ to + and - to -).
   • Connect the solar panel cables to the PV terminals on the charge controller. Ensure correct polarity.
   • Connect the load cables to the load terminals on the charge controller (optional). Ensure correct polarity.
3. Sensore di temperatura: Connect the included temperature sensor cable to the designated port on the controller. Place the sensor near the battery to enable accurate temperature compensation for charging.
4. Accensione iniziale: Once all connections are secure, the controller will power on and display system information on the LCD.

Importante: collegare sempre prima la batteria e scollegarla per ultima per evitare danni al controller.

6. Istruzioni per l'uso

The LCD display and buttons allow you to monitor and configure the charge controller.

6.1. Navigazione del display LCD

Use the buttons on the front panel to navigate through the display screens and adjust settings. Refer to the on-screen prompts for specific actions like 'Select' or 'Enter'.

6.2. Selezione del tipo di batteria

The controller automatically detects 12V/24V system voltages for non-lithium batteries. For lithium batteries, you must manually adjust the battery voltage setting through the controller's menu to ensure proper charging parameters.

6.3. Lithium Battery Activation

The controller includes a lithium battery activation function. This feature allows charging of deeply discharged lithium batteries that might otherwise be unresponsive.
