Energy Storage PCS
From 215kW to 6,000kW — air-cooled and liquid-cooled, 690V & 800V AC, Grid-Forming capable.
The ES Series is the core power conversion unit in any battery energy storage system — the component that decides how efficiently energy moves, how fast the system responds, and whether the station qualifies for the grid services that pay.
Why the ES Series
Maximum conversion efficiency above 99% through the three-level topology Soaring introduced in 2016. Charge/discharge switching in 8.5ms — the national standard allows 100ms. VSG-based grid-forming control certified by CPRI in China’s first batch (2023). And transformerless multi-unit paralleling, pioneered by Soaring in 2010, that cuts cost and footprint on every project.
The Range
Eleven power classes from 215kW to 6,000kW, in 690V and 800V AC variants, air-cooled and liquid-cooled. The liquid-cooled ES-3550K, ES-5000K and ES-6000K suit high power density and high ambient temperature sites. The CE-certified ESG-2500K serves export markets.
