Can a PV inverter be used if grid tied?

The inverter used in stand alone operation of a PV energy systemshould not be used if the system is to grid tied. Should there be a grid outage, the PV energy system would still be supplying the grid creating a possible safety hazard to linesmen and grid customers.

Can I use the same PV inverter?

in principleyes you can use the same PV inverter. If you are in a stand alone system you should however have some source to operate in grid forming mode, keeping the frequency constant. Usually, in such microgrid scenario you have a diesel generator for that, since the PV obviously generates power only when the sun shines.

What is a stand-alone PV system?
