4. Operasyon Modes

The VEVOR Hybrid Solar Inverter offers flexible operating modes to suit various power management needs. These modes can be configured via the integrated LCD display.

4.1 Mòd chaje

The inverter supports three distinct charging modes:

• Solè chaje: Prioritizes charging the battery using power from solar panels.
• Utility Charging: Charges the battery using power from the AC utility grid.
• Chaje Ibrid: Combines solar and utility power to charge the battery, optimizing charging efficiency and speed.

4.2 Load Output Modes

The inverter provides four load output modes to manage power distribution to connected appliances:

• UTL Mode (Utility Priority): The inverter primarily uses utility power to supply the load. Solar power is used to charge the battery.
• SOL Mode (Solar Priority): The inverter prioritizes solar power to supply the load. If solar power is insufficient, it will draw from the battery.
• Mòd SBU (Solè-Batri-Itilite): The inverter first uses solar power, then battery power. If both are insufficient, it switches to utility power.
• Mòd SUB (Solè-Itilite-Batri): The inverter first uses solar power, then utility power. If both are insufficient, it switches to battery power.
