7. Operating Modes
The Anern Hybrid Solar Inverter offers flexible operating modes to suit various energy management needs.
7.1 Charging Modes
You can configure the inverter to prioritize different power sources for battery charging:
- Solar Only: Batteries are charged exclusively by solar power.
- Solar and Utility: Batteries are charged by both solar and utility power.
- Solar Priority: Solar power is prioritized for charging; utility power is used only when solar power is insufficient.
7.2 Output Modes
The inverter can be configured to prioritize different power sources for supplying loads:
- Solar Priority: Loads are primarily powered by solar energy. If solar is insufficient, battery power or utility power (depending on configuration) will be used.
- Utility Priority: Loads are primarily powered by the utility grid. Solar power is used for charging or when the grid is unavailable.
- SBU Mode (Solar-Battery-Utility): Loads are first powered by solar, then by battery, and finally by the utility grid if both solar and battery are insufficient.
7.3 RGB LCD Display Indicators

- Red: Battery Mode
- Blue: Utility Mode
- Purple: PV Mode
8. Maintenance
Regular maintenance ensures the longevity and optimal performance of your inverter.
- Cleaning: Periodically clean the inverter's exterior, especially the ventilation openings, to prevent dust buildup. The built-in anti-dust kit helps, but regular cleaning is still recommended.
- Connections Check: Annually inspect all electrical connections (PV, battery, AC input/output) for tightness and signs of corrosion. Loose connections can cause overheating and damage.
- Battery Health: Monitor battery voltage and performance regularly. The smart battery charge design helps optimize battery life, but external battery maintenance may be required depending on battery type.
- Environment: Ensure the installation environment remains within the specified operating temperature and humidity ranges.
