ESS GU 80kWh UPS Lithium Backup Battery
At a glance
ESS GU 80kWh UPS Lithium Backup Battery is built on LiFePO₄ cells at 192VDC with 80.64kWh stored, delivering up to 420A discharge. It takes over critical loads the instant mains supply fails, for data centres, telecom rooms and industrial UPS retrofits.
Key Features
- LiFePO₄ cells at 192VDC battery voltage
- Stored energy 80.64kWh
- Up to 420A discharge for high-rate pulse loads
- Wide voltage window; CAN / RS485 interlock with the UPS host
- Rack-mounted design with modular capacity extension
Product Description
The ESS GU series lithium backup battery pairs LiFePO₄ cells with 2C / 4C high-rate discharge, taking over critical loads the moment mains power drops. It suits data centres, telecom rooms, medical sites and industrial UPS hosts.
The ESS GU 80kWh runs at 192VDC with roughly 80.64kWh usable, measures 1100×700×2200mm and weighs about 750kg. Each cabinet is wired, insulation-tested and function-tested before shipment, so it can be specified and ordered once the load list and local grid requirements are confirmed.

Product FAQ
Which UPS applications suit the ESS GU 80kWh pack?
It targets data centres, telecom base stations and equipment rooms, medical equipment, rail transit and industrial-control UPS hosts — for both lithium retrofits of the DC side and new builds replacing lead-acid strings.
What about high-rate discharge?
This model delivers up to 420A discharge and 105A charge, covering short high-current UPS discharge and fast recharge.
How compatible is it with existing UPS hosts?
Battery telemetry is exchanged over CAN / RS485 and can be opened to the host protocol. Retrofit projects must first verify the UPS DC bus voltage and charge-management logic.
Space and floor loading?
Rack-mounted cabinet, 1100×700×2200mm, roughly 750kg. Confirm floor loading for the planned row layout.
Custom builds and private labelling?
Capacity, rate, protocol, cabinet appearance and branding can all be customised — contact us for the corresponding lead time.
