5.3 Configurable Modes and Settings

5.3.1 Charging Modes

The inverter supports four charging modes:

Figure 5.2: Four Charging Modes. This diagram illustrates the four available charging modes: Solar First (PV priority), Mains First (Utility priority), Hybrid Charging (PV and Utility combined), and Only Solar (PV only).

• Solar First: Priority is given to PV charging. Mains charging starts only if PV power is insufficient.
• Mains First: Priority is given to mains charging. PV charging starts only if mains power fails.
• Hybrid Charging: Combines PV and mains power for charging. PV power is prioritized, and mains power supplements if PV is insufficient.
• Only Solar: Only PV power is used for charging; mains charging is not initiated.

5.3.2 Load Output Modes

The inverter offers four load output modes:

Figure 5.3: Four Load Output Modes. This diagram illustrates the four available load output modes: Solar First (PV and battery priority), Mains First (Inverter power supply only when mains fails), Inverter First (Mains power supply only when battery is under-voltage), and Hybrid Output (PV and utility together, with grid feedback if enabled).

• Solar First: PV and battery power the load. Switches to mains power if PV and battery are insufficient.
• Mains First: Inverter supplies power only when mains power fails. Otherwise, loads are powered by mains.
• Inverter First: Mains power supplies loads only when the battery is under-voltage. Otherwise, inverter powers loads.
• Hybrid Output: Loads are powered by PV and utility together. If grid connection is enabled, surplus PV energy can be fed back to the grid.

5.3.3 Sectional Charging/Discharging (Peak-Valley Tariff)

This function allows you to optimize energy usage based on electricity tariffs by setting specific time periods for charging from the grid or discharging the battery.

Figure 5.4: Peak-Valley Electricity Tariff Function. This image explains the sectional charging and discharging functions, allowing users to set three definable periods (00:00 to 23:59) for mains charging (BT1ST Mode) or battery discharge (AC1ST Mode) to align with local electricity tariff standards.

• BT1ST Mode (Sectional Charging Function): Set specific times for the inverter to charge batteries from the mains power.
• AC1ST Mode (Sectional Discharging Function): Set specific times for the inverter to discharge batteries to power loads.
• Users can define up to 3 periods between 00:00 and 23:59.

5.3.4 ECO Mode (Power Saving)

When ECO mode is enabled, if the load connected to the inverter is below 50W for 5 minutes, the inverter output will turn off to reduce idle power consumption. To resume output, press the ON/OFF switch to "OFF" and then back to "ON".

Figure 5.5: ECO Mode for Power Saving. This image illustrates the ECO mode feature, which reduces no-load loss by temporarily shutting down the inverter output when the load is below 50W for 5 minutes. It also shows how to reactivate the output.

5.3.5 Battery Type Compatibility

The inverter is compatible with various battery types, including FLD, SLD, AGM, GEL, and Lithium (LI). It also supports a user-defined setting.

Figure 5.6: Battery Type Compatibility. This image shows the inverter's compatibility with various 48V battery types, including FLD, SLD, AGM, GEL, and Lithium, along with a user-defined option. It also highlights the battery activation function for dormant lithium-ion batteries.
