6. Operating Modes

The inverter offers flexible charging and output modes to suit various energy management needs.

6.1 Charging Modes

1. Solar First: Prioritizes solar power for charging the battery.
2. Solar and Utility (Same Time): Utilizes both solar and utility power simultaneously for battery charging.
3. Only Solar: Charges the battery exclusively from solar power.

6.2 Output Modes

1. Solar First: Prioritizes solar power to supply connected loads. Utility power and battery serve as backup.
2. Utility First: Prioritizes utility power to supply connected loads. Solar power and battery serve as backup.
3. SBU Priority (Solar-Battery-Utility): Prioritizes solar power, then battery power, and finally utility power for connected loads.

7. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your inverter.

• Inspection: Periodically check all wiring connections for tightness, signs of wear, or corrosion.
• Cleaning: Keep the inverter's ventilation openings clear of dust and debris. The unit has a built-in anti-dust kit, but regular cleaning is still recommended. Use a dry, soft cloth for cleaning the exterior. Do not use liquid cleaners or solvents.
• Environment: Ensure the operating environment remains within the specified temperature and humidity ranges.
