Hello,
In this scenario, several factors could be at play. Here are some potential causes and troubleshooting steps you can consider:
- Ensure that the inverter is compatible with the DC voltage and power output from your PV system and DC-DC converter.
- Check the inverter's input voltage range and make sure your PV system's output falls within this range.
- Check for any inverter settings related to grid-tied operation, as some inverters have specific modes for grid connection.
- Ensure that the inverter is properly synchronized with the grid. Grid-tied inverters need to match the grid's voltage, frequency, and phase.
- Consider the load conditions on the grid side. If there is a significant load connected, it might affect the inverter's ability to maintain the desired output voltage.
Hope it helps!
