What is inverter for grid connected PV system?

Inverter is essential component in grid connected PV systems. This review focus on the standards of inverter for grid connected PV system, several inverter topologies for connecting PV panels to the three phase or single phase grid with their advantages and limitations.

Can a 3 phase inverter be used for solar?

The easiest way to do that is simply to use a 3 phase inverter. If you have skinny wires from your meter to the grid, then you may have a problem with high voltage drops. If the voltage drop is too high you may not be able to install solar. A 3 phase inverter spreads the power across 3 phases, so makes the voltage drop on each wire 3x smaller.
