GoodWe & GoodWe BAT112 with ET 100 and STS box

GoodWe Blackout Ready Commercial storage system Package ET100 + BAT112 + STS

The GoodWe Blackout Ready Commercial Storage System combines the GW100K-ET-G10 hybrid inverter, the GoodWe BAT112 high-voltage battery system and the GoodWe GW125K-STS-G10 Static Transfer Switch Box to form a fully integrated storage system for commercial and industrial applications with backup power capability.

The ET100 controls the flow of energy during grid operation and supports key use cases such as Self-consumption optimisation, peak shaving and time-of-use billing. In conjunction with the STS box, the system enables UPS-like switching between the grid and backup power supply, ensuring a secure power supply to critical loads even during grid outages. The BAT112 battery system allows for the creation of large, scalable storage capacities.

According to GoodWe, an expansion to parallel ET100 systems with larger STS variants is planned from the end of April 2026.
