Will PV still work if the grid goes down?

Will PV still work if the grid goes down?

Jan 18, 2024

Conventional grid-connected PV systems usually stop working when there is a power cut in the grid. This is to protect the safety of

maintenance personnel and to prevent the PV system from injecting power into the grid. For example, if a crew on the grid is repairing

a line but is unaware that a PV system is operating, they may be at risk by thinking the line is disconnected. In addition, continuous

operation of the PV system could result in electricity flowing back into the grid, jeopardizing the safety of electrical equipment and users.

However, there are also systems called microgrids that can continue to utilize a PV system in the event of a grid outage. A microgrid is

a stand-alone power system consisting of multiple renewable energy generators (e.g., solar PV), energy storage devices (e.g.,

batteries), and loads. In the event of a grid outage, the micro-grid can continue to operate, providing power to internal loads without

relying on the main grid.
