When the power grid is running smoothly, this system allows for a seamless energy exchange. However, when the power goes out, your grid-tied solar system is designed with an automatic shutoff as a crucial safety feature.
When the grid goes down, utility workers are out in the field working to repair damaged lines. If your system continued to send power to the grid during an outage, it could pose a risk to the workers trying to fix the power lines. The automatic shutdown ensures that no power is flowing back into the grid, keeping the workers safe from unexpected electrical currents.
