- Solar First: Prioritizes charging from solar panels.
- Mains & Solar Hybrid Charging: Utilizes both grid and solar for charging.
5.2 Output Modes
There are 3 available output modes for power supply:
- Solar First (CSO): Prioritizes solar power for the load.
- Mains First (UTI): Prioritizes utility grid power for the load.
- SBU Priority (SBU): Prioritizes solar, then battery, then utility for the load.

5.3 Lithium Battery Settings (from video demonstration)
When using lithium batteries, specific settings must be configured on the inverter's LCD panel to match the battery's characteristics. This ensures optimal performance and battery longevity.
Image Description: Close-up of the inverter's LCD display and function buttons, showing the interface for adjusting settings. A separate box displays specifications for a 'LITHIUM PHOSPHATE (LiFePO4) BATTERY', including Nominal Voltage (12.8V), Rated Capacity (100Ah), Charge Voltage (14.6V), Max Charging Current (20A), Max Discharging Current (100A), Discharge Cut-Off Voltage (9.5V).
- Setting the lithium battery charging mode: Navigate through the menu to set the appropriate charging mode.
- Option 05 (USE): To set this option, you must know the lithium battery's charging cutoff voltage and discharging cutoff voltage values.
- Option 26: Set this option according to the value of the lithium battery charging cutoff voltage (e.g., 14.6V for a 12.8V LiFePO4 battery).
- Option 27: Set this option according to the value of the lithium battery charging cutoff voltage.
- Option 29: Set this option according to the value of the lithium battery discharge cutoff voltage (e.g., 9.5V for a 12.8V LiFePO4 battery).
- Option 12: This setting determines the battery voltage at which the inverter stops working and the utility power supply automatically charges the battery.
- Option 13: This setting defines the battery voltage at which the mains power supply stops and switches to battery power supply.
- Option 16 (C50): This option is used to set Solar Priority Charging.
5.4 Wi-Fi Communication (Optional)
If equipped with the optional Wi-Fi module, you can monitor the inverter's operation remotely. This allows you to check the inverter's status anytime, anywhere, using a mobile phone or web interface.

- Ensure the operating environment temperatures are within the specified range (-10°C to 55°C).
7. Troubleshooting
This section provides guidance on common issues. For complex problems, contact customer support.
Common Issues:
- Inverter not turning on: Ensure the battery is connected first and fully charged. Check all input connections.
- No power output: Verify the load is correctly connected and within the inverter's rated capacity. Check for overload or short circuit protection activation.
- Fault indicator lit: Refer to the inverter's specific fault codes (if available in the full manual) to diagnose the issue. Common faults include overload, high temperature, or short circuit.
- Does the inverter work without a battery? No, a battery is required for the inverter to function as intended.
8. User Tips
- Battery Sizing: The battery capacity should be carefully selected based on your specific load requirements and application scenarios. Incorrect sizing can lead to insufficient power or wasted generation.
- Connection Order: Always connect the battery first during startup and disconnect it last during shutdown to prevent damage to the inverter or battery.
- Lithium Battery Settings: If using lithium batteries, meticulously set the charging and discharging cutoff voltages on the inverter's LCD panel according to your battery manufacturer's specifications. This is crucial for battery health and safety.
- Load Management: Avoid overloading the inverter. Distribute your loads to stay within the inverter's continuous power rating.
