FAQs 6

How can photovoltaic inverters prevent islanding effects?

The photovoltaic sector is embarking on a new phase of development. To ensure that photovoltaic power generation systems can prevent islanding effects when connected to the grid, grid-connected photovoltaic inverters are being adjusted and updated in alignment with the “14th Five-Year Plan.”

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.

Why are grid-connected photovoltaic inverters being adjusted?

To ensure that photovoltaic power generation systems can prevent islanding effects when connected to the grid, grid-connected photovoltaic inverters are being adjusted and updated in alignment with the “14th Five-Year Plan.” This is to meet the goals of the energy transition and domestic photovoltaic market demands.

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.

Does a grid-connected inverter need islanding detection?
