Description

The Growatt SYN 100-XH-30 Backup Box is a dependable backup power solution designed specifically for use with Growatt three-phase XH series hybrid inverters. Engineered to provide seamless emergency power during grid outages, this intelligent backup box automatically switches between the utility grid and battery storage system, ensuring that essential loads remain powered when they are needed most.
