UniC AG440: high-performance new all-in-one C&I solution.
An all-in-one commercial and industrial battery energy storage cabinet, co-developed by YES-EU. 440.96 kWh in a single liquid-cooled, IP55 outdoor unit, built on 530 Ah cells in a 1P52S × 5S configuration. A dual-inverter design covers four system variants, internal or external inverter in a 2h or 4h configuration, from 92 kW to 220 kW. It delivers a 10,000-cycle service life and scales up to 45 units, roughly 20 MWh, per node.
Commercial and industrial storage in one cabinet.
The UniC AG440 packs 440.96 kWh into a single all-in-one cabinet with 50% higher energy density and 50% less floor space than 200 kWh units for the same capacity. Packs are liquid-cooled, the PCS is air-cooled, and the whole cabinet is delivered factory-assembled to cut on-site work and cost. On-grid and off-grid ready with a black start function on the internal-inverter variants, and compatible with local inverters where a project calls for them.
Denser, safer, built for the long term.
-
More energy, less space
50% higher energy density than 200 kWh units and 50% less floor space for the same capacity. Whole-cabinet delivery cuts on-site work and cost, so a single 1470 × 2490 × 1500 mm footprint carries the full 440.96 kWh.
-
Ultimate flexibility
Dual-inverter design, 2H and 4H compatible, with the inverter integrated at the factory or mounted externally on site. Compatible with local inverters, on-grid and off-grid multi-use ready, and scalable up to 45 units, roughly 20 MWh, per node.
-
Certified system-level safety
PPB level cell safety failure rate and reinforced electrical and mechanical design. Multi-level fire protection combines explosion venting, aerosol and water spray, and the system is UL9540A system-level thermal-runaway tested.
-
Grows with your business
10,000-cycle long life with 25% more throughput over the full lifespan. Available as a total solution with an STS cabinet, and backed by an Ampace and CATL local service network.
-
Reliable in cold weather
Enhanced thermal insulation design means no heating is required at −20 °C at one cycle per day, and the cabinet operates down to −30 °C. Rated across −25 °C to 55 °C with derating above 45 °C and above 2000 m.
-
Where it fits
Micro-grids, manufacturing plants, retail and supermarket sites, logistics centres and public facilities. IP55, C4-M corrosion rated as standard with C5-M optional, and rated to 3000 m altitude.
