Grid-following inverter
Also known as: GFL, Current Source Inverter
A power conversion system that synchronises to the existing grid voltage and frequency signal — it "follows" the grid. Grid-following inverters require a stable grid reference to operate, meaning they cannot energise a dead network on their own. Contrast with grid-forming inverters.
