What is grid-connected PV inverter topology?
Summary of grid-connected PV inverter topology In the grid-connected PV system, the DC power of the PV array should be converted into the AC power with proper voltage magnitude, frequency and phase to be connected to the utility grid. Under this condition, a DC-to-AC converter which is better known as inverter is required.

A micro inverter operating in grid-connected mode should satisfy the grid connection standards in terms of power quality, THD ratios, islanding detection, grid interfacing limits for voltage and frequency, and grounding.
How do grid-following inverters work?
Traditional “grid-following” inverters require an outside signal from the electrical grid to determine when the switching will occur in order to produce a sine wave that can be injected into the power grid. In these systems, the power from the grid provides a signal that the inverter tries to match.
