This image illustrates the temperature compensation capability of the controller, ensuring optimal battery charging performance in both hot and cold environments.

4. Installazione e cablaggio

Una corretta installazione è fondamentale per il funzionamento sicuro ed efficiente del regolatore di carica solare. Seguire attentamente questi passaggi.

4.1 Schema elettrico

Figura 4.1: Wiring diagram for the PowMr MPPT Solar Charge Controller.

This diagram illustrates the correct connection order for the battery, solar panels, DC load, and optional inverter. A temperature sensor is also shown.

4.2 Fasi di connessione

1. Collegare prima la batteria: Connect the battery to the charge controller's battery terminals. Ensure correct polarity. The controller will auto-detect 12V or 24V system voltage.
2. Collegare i pannelli solari: Connect the solar panels to the PV input terminals. Ensure correct polarity. The controller will begin charging if sufficient sunlight is available.
3. Collegamento del carico CC (facoltativo): Se si utilizza un carico CC direttamente dal controller, collegarlo ai terminali del carico.
4. Collegamento dell'inverter (facoltativo): If using an inverter, connect it to the battery terminals (not directly to the load terminals of the controller).
5. Collegare il sensore di temperatura: For accurate temperature compensation, connect the provided temperature sensor to the designated port on the controller and place the sensor near the battery.

Ordine di disconnessione: To disconnect the system, always follow the reverse order: Disconnect load, then solar panels, then battery.

5. Istruzioni per l'uso

This section details how to monitor and configure your charge controller using its integrated LCD display and the optional Bluetooth mobile application.
