How does SunVault know when to go into backup operation?

SunVault is designed to seamlessly transition from utility grid power to backup power when the utility grid falters. This seamless transition can occur as quickly as the blink of an eye.

The utility grid is a very dynamic environment where conditions change by the millisecond. SunVault was designed with this in mind and makes decisions based on grid conditions (voltage and frequency) and utility requirements within 24 milliseconds!
