2.3 Connection Steps

Follow these steps for proper connection of the inverter to your solar panels and the AC grid. Always ensure safety precautions are followed, including disconnecting power before making any connections.

1. Connect the DC input from your solar panels to the inverter's DC input terminals. Ensure correct polarity (positive to positive, negative to negative).
2. Connect the AC output of the inverter to your home's electrical grid.
3. If using the limiter sensor, connect it to the designated port on the inverter.
4. If using the optional WiFi module, connect it to the remote port.
5. Turn on the inverter. The red light will illuminate, followed by a flashing green light, and then a solid green light once grid connection is established.

3.2 Limiter Function

The integrated current limiter ensures that the inverter only supplies the necessary power to your household loads, preventing excess energy from being fed back into the grid if not desired. This optimizes self-consumption.

3.3 MPPT Technology

Maximum Power Point Tracking (MPPT) continuously adjusts the inverter's operating point to extract the maximum possible power from your solar panels under varying conditions, such as sunlight intensity and temperature.

3.4 WiFi Monitoring (Optional)

With the optional WiFi module, you can monitor your inverter's performance remotely via a smartphone application. This allows for real-time data viewing, historical data analysis, and system configuration.

4. Maintenance

Regular maintenance ensures optimal performance and longevity of your inverter. Always disconnect the inverter from both DC and AC power sources before performing any maintenance.

• Cleaning: Periodically clean the exterior of the inverter and cooling fins to prevent dust buildup, which can hinder heat dissipation. Use a soft, dry cloth. Do not use liquid cleaners.
• Connections Check: Annually inspect all electrical connections (DC input, AC output, limiter sensor, WiFi module) to ensure they are secure and free from corrosion.
• Ventilation: Ensure the area around the inverter is clear of obstructions to allow for proper airflow and cooling.
• Firmware Updates: Check the manufacturer's website or the monitoring app for any available firmware updates to ensure your inverter operates with the latest features and improvements.

5. Troubleshooting

If you encounter issues with your inverter, refer to the following common troubleshooting steps. For persistent problems, contact customer support.

• No Power Output:
  • Check if the DC input from solar panels is connected and providing sufficient voltage (22-60V DC).
  • Verify the AC grid connection is secure and the main breaker is on.
  • Ensure the inverter's power switch is in the "ON" position.
• Error Indicator Light:
  • Refer to the LCD display for specific error codes or messages.
  • Check for over-current, over-temperature, or reverse polarity conditions.
  • If an anti-islanding error occurs, ensure the grid connection is stable.
• Low Power Generation:
  • Inspect solar panels for shading, dirt, or damage.
  • Verify DC input voltage and current are within the inverter's operating range.
  • Check ambient temperature to ensure the inverter is operating within its optimal range (-20°C to +50°C).
• WiFi Connection Issues:
  • Ensure the WiFi module is correctly installed and powered.
  • Verify your home WiFi network is 2.4GHz (5GHz is not supported).
  • Check the WiFi signal strength at the inverter's location.
  • Follow the rapid configuration steps in the monitoring app.
