ABB 11RT G3 LIB 2–3 kVA UPS External Battery Pack

Product Overview

Compatibility and Integration

This external battery module is engineered specifically for the PowerValue 11RT G3 LiB UPS range (2–3 kVA). It interfaces directly with the UPS’s battery connector and supports up to four external modules to scale runtime according to application needs. The UPS can automatically detect connected EBMs and adjust runtime calculations accordingly.

According to ABB documentation, the module’s mechanical footprint matches the 1U form factor of other accessories in the G3 series, ensuring a clean and consistent rack‑mount or tower installation when paired with the appropriate mounting kits.

Extended Runtime Capability

With EBMs installed, the combined UPS + external battery configuration can deliver significantly extended autonomy compared with internal batteries alone. For a 3 kVA UPS in the PowerValue 11RT G3 LiB series, typical runtime extensions per module—based on ABB’s technical projections—are as follows (approximate and subject to load conditions, temperature, and battery age):

• 1 module: extended runtime beyond internal battery only

• 2 modules: further increased runtime

• 3–4 modules: progressively greater autonomy suitable for longer outages or controlled shutdown scenarios.

Exact runtime figures will vary based on connected load and installation environment.

Design and Build

The battery module is housed in a compact enclosure designed for indoor deployment in IT closets, server rooms, and telecom cabinets. It weighs approximately 17.4 kg and has dimensions matching UPS accessory standards for the G3 LiB 1–3 kVA line.

The unit integrates seamlessly with the UPS battery management system, ensuring safe charging, discharge control, and system protection. Installation should follow ABB’s guidelines for connection polarity and secure fastening to support reliable operation over extended periods.
