Technical FAQs 4

What causes a solar inverter to fail?

The AC voltage overrange is the most common failure of the solar inverter connected with the PV grid system. This is because the grid voltage is not constant and it will change with the changing of the load and current. At the same time, the output voltage of the inverter will be affected by the grid voltage.

What happens if a grid connected inverter is too far away?

If the grid-connected inverter is too far away from the grid connection point, the voltage difference on the AC terminal side of the inverter will increase. When the inverter is connected to the grid-connected voltage range, the inverter will display the grid overvoltage.

Why does my inverter display a grid overvoltage?

When the inverter is connected to the grid-connected voltage range, the inverter will display the grid overvoltage. In addition, the cable used by the inverter to the grid point is too long, too thin, entangled or the material is not in compliance, which will lead to an increase in the voltage difference at the AC terminal of the inverter.

What to do if grid-connected inverter shows AC overvoltage problem?

What to do if “Grid-connected inverter shows AC overvoltage problem”. According to the relevant regulations, the PV grid-connected inverter must work within the specified grid voltage range, can be monitored in real time and synchronized with the grid voltage.
