Multiple Modular Systems
Each Uni.System delivers 600kW power and 2.2MWh maximum energy in a compact footprint of only five 20’ containers. Designed to be modular, multiple Uni.Systems can be deployed and operated with a density of more than 20MW per acre, and 40MW per acre if the containers are double-stacked.

Field-Rugged Design
UET’s breakthrough electrolyte has been rigorously tested for several years and enables a unique set of compelling field characteristics:
- Cycle life agnostic exceeding 10,000 cycles
- SOC agnostic providing 100% capacity utilization over 20 years
- Charge agnostic from partial opportunity charging to extreme ripple currents
- Discharge agnostic with system flexibility from fractions of seconds, to 15 hours
- Temperature agnostic operation from -40°C to +50°C (-40°F to +122°F)
- Location agnostic from sea level to 10,000 feet (3km)
The Uni.SystemTM integrates the abuse tolerant UET electrolyte; a state-of-the-art containerized design derived from multiple decades of design experience among the UET team; mature large-scale stacks with more than 7 years of field deployment and over a dozen systems in the field; and optimized power electronics and controls at each system level (from cell to site).
