SMA SBS-ABU-200-US-10 Automatic Back-Up Unit, For Sunny Boy Storage Inverters, 120/240VAC, 200A, NEMA 3R

SMA provides Additional peace of mind with SMA residential storage solutions

The SMA SBS-ABU-200-US-10 Automatic Backup Unit is an optional accessory for the Sunny Boy Storage inverter. It contains an automatic transfer switch, SMA Backup Unit Controller, overcurrent protection for the inverter(s)and an integrated energy meter and current transformers. In the event of grid failure, the Automatic Backup Unit disconnects the PV system, loads and the Sunny Boy Storage inverter from the utility grid and creates a battery-backup grid. The battery-backup grid supplies loads that should continue to be supplied with electricity in the event of grid failure. When the grid is down, the Sunny Boy Storage supplies the loads with energy after a short switching time. The PV system supplies additional energy that can be used to supply the loads and charge the battery.
