The protection functions are as follows: The overcurrent protection should be set on the AC output side of the solar inverter. When a short circuit is detected on the grid side, the solar inverter should stop supplying power to the grid within 0.1 second and issue a warning signal.
After the fault is removed, the solar inverter should work normally. The solar on grid inverter should have lightning-prevention protection function, and the technical index of the lightning protection device should ensure to absorb the expected impact energy.
the inverter should be equipped with lightning protection device and 6000V surge protection.
