4.2 Charging Modes
The inverter offers four distinct charging modes to optimize battery charging based on available power sources.
- Solar First: Prioritizes solar power for charging. Grid charging starts only if PV fails.
- Mains First: Prioritizes mains power for charging. PV charging starts only if mains fails.
- Hybrid Charging: Prioritizes PV MPPT charging, supplementing with mains power if PV energy is insufficient.
- Only Solar: Only PV charging is initiated; no mains charging.

4.3 Output Modes
Select from four output modes to manage power delivery to your loads.
- Solar First: Maximizes the use of green solar energy. Suitable for regions with stable power grids.
- Mains First: Switches to inverter power supply only when Mains power has failed (UPS function).
- Inverter First: Switches to Mains power supply only when the battery is under-voltage. Maximizes DC energy use.
- Hybrid Output and Grid Connection: In utility bypass state, if no battery is connected or battery is full, load is supplied by PV and utility. Surplus PV can be fed back to the grid if grid connection is enabled.

4.4 Battery Compatibility and Batteryless Mode
The inverter is compatible with various 48V battery types and supports operation without a battery.
- Compatible Battery Types: AGM, Gel, Lead-acid, Lithium, LiFePO4, and User-Defined.
- Batteryless Mode: Can power loads directly from PV or AC grid without a connected battery.
- Lithium Battery Activation: Features a dual activation function to wake up dormant Li-ion batteries using mains or PV power.

4.5 ECO Mode and Time-of-Use Programming
The inverter includes an ECO mode for energy saving and supports time-of-use programming.
- ECO Mode: If the load is less than 50W, the inverter delays for 5 minutes then shuts off. It restarts output when the load increases.
- Time-of-Use Programming: Allows for 24/7 programming of off-peak charging and discharging to optimize energy costs.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your inverter.
- Keep the inverter clean and free from dust. The unit features a dust-proof cover.
- Ensure proper ventilation around the inverter. The cooling fans should not be obstructed.
- Periodically check all electrical connections for tightness and signs of corrosion.
- Monitor the LCD display for any error codes or warnings.
