Technical FAQs 4

What are the protection functions of a solar inverter?

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.

How to choose a solar inverter?

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. When the polarity of the PV array is reversed, the solar inverter should be protected without damage.

Does a solar inverter have a power limiting function?

If the solar inverter input has a power limiting function, when the power output of the PV array exceeds the maximum DC input power allowed by the solar inverter, the inverter automatically limits the current operation to the maximum allowable AC output power. Solar inverters should have reliable and complete unplanned island protection functions.

What should a solar inverter do after a fault is removed?

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.
