6. Operating Modes
The Anern Hybrid Solar Inverter offers flexible operating modes to suit various energy management needs.
Charging Modes (3 Options)
Figure 6.1: Overview of charging and output modes.
- Solar Only (CSO): Solar energy is the primary source for charging the battery. The utility grid charges the battery only when solar energy is unavailable.
- Solar and Utility (SNU): Solar energy and the utility grid charge the battery simultaneously.
- Solar Priority (OSO): Solar energy is the sole charging source, regardless of its availability.
Output Modes (4 Options)
- USB - Utility First: Loads are primarily powered by the utility grid. Solar and battery power are only used if the utility company cannot supply power.
- SUB - Solar First (Standard): If solar energy is insufficient to power all connected loads, the grid supplies the loads simultaneously. The battery powers the loads only in two cases: if solar power is insufficient and grid power is unavailable, or if the grid is unavailable.
- SUB - Priority: If solar energy is insufficient to power all connected loads, the battery powers the loads simultaneously. The utility company then supplies the loads with power when the battery voltage drops below the warning value for low values or in program 12.
- MKS - Priority: Solar power has priority over loads. If solar power is insufficient, the loads are simultaneously supplied by the grid. The batteries serve as backup power.
RGB Operating Modes
The RGB display automatically changes color based on the inverter's operating status:

7. Maintenance
To ensure the longevity and optimal performance of your Anern Hybrid Solar Inverter, regular maintenance is recommended.
- Regular Cleaning: Keep the inverter's exterior clean and free from dust and debris. Ensure ventilation openings are not blocked.
- Connection Checks: Periodically inspect all electrical connections (PV, battery, AC input/output) for tightness and signs of corrosion. Loose connections can lead to overheating and poor performance.
- Environmental Conditions: Ensure the inverter is installed in a well-ventilated area, away from direct sunlight, moisture, and extreme temperatures.
- Firmware Updates: Check the manufacturer's website or app for any available firmware updates to ensure your inverter has the latest features and bug fixes.
8. Troubleshooting
If you encounter issues with your inverter, consider the following general troubleshooting steps:
- No Power/Display Off: Check all power connections, including battery, PV, and AC input. Ensure circuit breakers are in the ON position. Verify battery voltage is within the operating range.
- No Output Power: Check the load connections and ensure the inverter is not in an error state (indicated by the display or fault indicator). Verify that the output mode is correctly configured.
- Low Output Power: Ensure PV input is sufficient and batteries are adequately charged. Check for any overload conditions.
- Overload Warning: Reduce the connected load. Ensure the starting power of inductive loads does not exceed the inverter's capacity.
- Overheating: Ensure proper ventilation around the inverter. Clear any obstructions from cooling fans.
- WiFi Connection Issues: Ensure the WiFi module is correctly installed and within range of your network. Refer to the WiFi module's specific instructions for setup.
For persistent issues, refer to the detailed troubleshooting section in the complete user manual (if available in PDF format) or contact customer support.
