How do PV inverters work?

Traditionally, PV inverters work in grid-following mode to output the maximum amount of power by controlling the output current. However, grid-forming inverters can support system voltage and frequency and play an important role in weak power grids. Inverters with two operation modes are attracting more attention.

What is a two-stage PV inverter?

The two-stage PV inverter consists of a front-end DC circuit and a rear-end AC circuit. The whole PV system adopts a hierarchical control strategy and has an independent DC link. The front-end circuit uses the maximum power point tracking (MPPT) of the PV array to control the energy fed to the rear-end stage.
