5. Operating Instructions
5.1 Charging Modes
The inverter supports four distinct charging modes to optimize battery charging based on available power sources.
- Solar First: Priority is given to charging by PV. Mains charging initiates only when PV power is insufficient.
- Mains First: Priority is given to charging by Mains Power. PV power charging initiates only when mains power is unavailable.
- Hybrid Charging: Combines PV and Mains Power charging. Priority is given to MPPT charging. Mains power supplements when PV energy is insufficient and stops when PV energy is sufficient.
- Only Solar: Only PV charging is initiated; no mains charging occurs.

5.2 Load Output Modes
The inverter offers flexible load output modes to manage power delivery to connected appliances.
- Solar First: PV and battery will power the load. Switches to Mains Power when PV fails.
- Mains First: Switches to inverter power supply only when Mains Power has failed.
- Inverter First: Switches to Mains Power supply only when the battery is under-voltage.
- Hybrid Output: In utility bypass state, when no battery is connected or when the battery is full, the load power is supplied by the PV and the utility together. If the hybrid function is enabled, surplus PV energy can be fed back to the grid if grid connection is enabled.

5.3 Intelligent Power Saving (ECO Mode)
The ECO mode reduces no-load loss by intelligently managing inverter output.
- When ECO mode is enabled, if the load is below 50W, the inverter output is delayed for 5 minutes and then turned off.
- To resume output, press the hull switch to the "OFF" state, then back to the "ON" state.

5.4 Peak-Valley Electricity Tariff and Sectional Functions
The inverter allows for optimized energy usage based on electricity tariffs.
- Sectional Charging Function (BT1ST Mode): Users can set specific time periods (3 definable periods between 00:00 and 23:59) for mains charging, aligning with lower electricity tariffs.
- Sectional Discharging Function (AC1ST Mode): Users can set specific time periods (3 definable periods between 00:00 and 23:59) for battery discharge, utilizing stored energy during peak tariff hours.
