Flip the DC disconnect switch to the ON position. This allows power from the solar panels to flow to the inverter. Keep a close eye on the inverter display. It should start to show signs of life, such as booting up or displaying a welcome message. If nothing happens, double-check your wiring and connections.

Monitor Inverter Startup

As the inverter starts up, monitor its display for any error messages or warnings. These messages can provide valuable clues about potential issues with the system. Refer to the inverter's manual for a detailed explanation of each error code. Common startup issues include:

• Grid Voltage Issues: If the grid voltage is outside the acceptable range, the inverter may display an error message and refuse to connect. Check the grid voltage with a multimeter to ensure it meets the inverter's requirements.
• Frequency Problems: Similar to voltage, the inverter may not connect if the grid frequency is incorrect. Verify the frequency with a multimeter and consult your utility provider if necessary.
• Communication Errors: If the inverter cannot communicate with the optimizers or monitoring system, it may display an error message. Check the wiring and connections to ensure proper communication.

Check Voltage and Current Readings

Use a multimeter to measure the voltage and current at various points in the system. This includes the voltage of each string, the current flowing through each string, and the voltage at the inverter's DC input. Compare these readings with the expected values based on your system design. Discrepancies can indicate wiring issues, faulty components, or incorrect string configurations.

SolarEdge Inverter Configuration

With the system powered up, it’s time to configure the SolarEdge inverter. This involves setting various parameters to optimize performance and ensure compliance with local regulations. Pay close attention to each setting, and don’t hesitate to consult the inverter’s manual for guidance.
