The Residential Static Transfer Switch (STS) is an intelligent switching solution designed for the ESA Series All-in-One energy storage system, supporting both single-phase and three-phase applications. It enables fast and seamless transitions between grid-connected and backup operation, ensuring uninterrupted power supply for essential household loads. During grid outages, the STS enables seamless transfer of critical loads to the ESA system and smooth reconnection once grid power is restored, enhancing home energy resilience, reliability, and energy independence.
