5. Operating Modes and Settings

The inverter offers various configurable settings to optimize performance based on your specific energy needs and battery type.

AC Output Priority Mode (Setting 01):

• UTI (Utility Priority Mode): Inverter switches to inverter mode only when utility power is unavailable. Load is powered by photovoltaic and battery power.
• SOL (Solar Priority Mode): Inverter prioritizes using solar power for the load. Utility power is used only when solar power is unavailable or battery voltage is below the set value.
• SBU (Inverter Priority Mode): Utility power is used only when battery voltage is below the set value.

Charging Modes (Setting 06):

• SNU (Hybrid Charging Mode): Both solar and utility can charge the battery, prioritizing solar. If solar is insufficient, utility supplements it.
• OSO (Solar Only Charging): Only solar is used to charge the battery; utility is not used.
• CSO (Solar Priority Charging): Prioritizes solar charging. Utility is used only when solar is unavailable.
• CUB (Utility Priority Charging): Solar is used only when utility is unavailable.
