7.2. Monitoring
The inverter features a built-in display for real-time monitoring of system performance, including PV input, battery status, AC output, and fault codes. Optional dataloggers and monitoring modes (GPRS/WiFi/Bluetooth/4G/LAN) allow for remote monitoring and data logging.
8. Maintenance
Regular maintenance ensures optimal performance and longevity of your inverter.
- Cleaning: Periodically clean the inverter's exterior and ventilation openings to prevent dust accumulation, which can hinder natural cooling. Use a soft, dry cloth.
- Inspection: Annually inspect all electrical connections for tightness and signs of corrosion. Check cables for damage.
- Environment: Ensure the installation environment remains within the specified operating temperature and humidity ranges.
Always disconnect power before performing any maintenance.
9. Troubleshooting
This section provides general guidance for common issues. For complex problems, contact technical support.
9.1. No Power Output
- Check if all DC and AC breakers are in the ON position.
- Verify PV input voltage and current.
- Check battery voltage and connections.
- Inspect for any fault codes displayed on the inverter screen.
9.2. Inverter Not Charging Battery
- Ensure PV input is sufficient and within operating range.
- Check battery temperature sensor connection and reading.
- Verify battery type settings in the inverter configuration.
9.3. Inverter Display Not Working
- Check the main power supply to the inverter.
- If the inverter has power but the display is blank, contact support.
10. User Tips
- For optimal performance, ensure your PV array is clean and free from shading.
- Regularly monitor your system's performance through the display or optional monitoring platforms to identify any anomalies early.
- Keep the inverter's ventilation clear to prevent overheating, especially in warmer climates.
