4. Configuración
Follow these steps for proper installation and connection of the solar charge controller:
- Montaxe: Mount the controller vertically on a wall or stable surface in a cool, dry, and well-ventilated area. Ensure sufficient clearance around the unit for heat dissipation.
- Conexión da batería: Conecta primeiro a batería aos terminais da batería do controlador. Asegúrate da polaridade correcta (+ a + e - a -). O controlador detectará automaticamente o volume da batería.tage.
- Conexión do panel solar: Connect the solar panels to the controller's PV terminals. Ensure correct polarity. The controller will begin charging the battery.
- Conexión de carga (opcional): Connect your DC loads to the controller's load terminals. Ensure correct polarity.
Importante: Conecta sempre primeiro a batería, despois os paneis solares e, finalmente, a carga. Desconecta na orde inversa: carga, despois os paneis solares e, finalmente, a batería.

5. Instrucións de funcionamento
5.1 Screen Interface Cycle
The controller's LCD display cycles through various parameters, providing real-time information about your solar system. Use the buttons to navigate or adjust settings.
Image 5.1: The screen interface cycle, illustrating different display modes for battery voltage, charging current, temperature, and fault indicators. It also shows steps for setting battery type, discharge cut-off voltage, charging cut-off voltage, float voltage, and load operating mode.
Nota: If the reading data for PV or Battery is constantly changing, the controller is actively finding the Maximum Power Point (MPP). This is normal operation. If the PV input power or voltage is insufficient, contact support.
5.2 Modos de carga
O controlador utiliza un módulo de 3 segundostage charging process to optimize battery health and performance:
- Carga masiva: Charges the battery at its maximum current until voltage rises to the absorption level.
- Constant Charging (Absorption): Mantén un volume constantetage, allowing the current to gradually decrease as the battery approaches full charge.
- Carga flotante: Unha vez que a batería estea completamente cargada, o volumetage is reduced to a lower level to maintain the battery at full capacity and prevent self-discharge.
