Grid-connected inverters are integrated into off-grid systems

What does a grid connected inverter do?

Photovoltaic grid-connected inverters rely on the large power grid to operate. When the power grid is disconnected, the grid-connected inverter will be in an island protection state and stop working. Its main function is to convert solar energy into electrical energy and transmit it through the power grid.

How does a grid forming inverter work?

Grid-forming inverters can start up a grid if it goes down—a process known as black start. 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.

What is an off-grid inverter?

Though fundamentally an off-grid inverter, this versatile model features grid input support—allowing it to draw power from the grid when solar and battery resources are insufficient. Commonly known as an off-grid hybrid inverter, it combines solar + battery + optional grid power, ensuring uninterrupted energy supply.

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.
