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.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.
What happens if AC voltage exceeds the inverter's limit?When the AC voltage exceeds the inverter's limit it causes a shut down. Once production stops the inverter will see the grid voltage decrease, so it will attempt to restart. This will continue to happen in a cycle throughout the day. It can be seen on monitoring platforms as multiple faults every day.
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.
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.
Why do inverters need to be stopped if grid voltage changes?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. When the grid encounters abnormal situation, the inverter power supply shall be stopped to avoid more serious damage on the grid.
Why do inverters need to be tripped?When the inverter detects that the grid voltage (AC voltage) is outside the specified range, the inverter The device must be tripped to stop working in order to ensure the safety of the equipment and protect the personal safety of the operat
