How does an islanding solar inverter work?

Your islanding solar inverter works independently from the power grid. If there's a storm or other event that knocks out the main power grid, your solar power system will continue running and providing power to your home. We mention this because many people mistake going solar with going off-grid, but that's typically not the case.

Do you need a solar inverter?

To achieve this effect, you need special inverters that can operate in solar inverter island mode and reliable batteries with sufficient capacity. Both the specialized inverters and backup battery storage required to power your home without the grid are more expensive than a typical solar power system.

How does a solar inverter work if the grid goes down?

If the grid goes down, your solar system is designed to turn off automatically to ensure the safety of utility workers fixing power lines. On the other hand, if you're completely off the grid, you're already on your own power island. Your islanding solar inverter works independently from the power grid.

What if solar islanding wasn't prevented?

Here's what could happen if solar islanding wasn’t prevented: The local grid goes down. However, your grid-tied solar power system still produces electricity. Once the panels have supplied electricity to your home, any excess energy goes into the grid.

Do solar panels have anti-Islanding inverters?

The short answer is no. UL Standard 1741 requires every grid-tied solar panel system to have a built-in anti-islanding solar inverter, and the solar industry follows that standard.
