About AlphaESS
AlphaESS (Alpha ESS Co., Ltd., Nantong, Jiangsu) integrates LFP energy storage systems from residential to utility scale and lists nine overseas subsidiaries on its datasheets. Its published C&I line comprises the stackable StaX-M30/M50 (96–217 kWh with 30/50 kW hybrid inverter), the STORION-H30/H50-G3 all-in-one cabinet (72–241 kWh), and the liquid-cooled STORION-LC-TB125 (261 kWh/125 kVA) and TB150 (313 kWh/150 kW, Standard and Ultra cycle-life versions). Larger systems are the Aster TB250/TB500 AC-coupled 20 ft container (705–1410 kWh with 500 kW PCS and transformer) and DC-only blocks: STORION-LC 836 cabinet (836 kWh, 1331 V) and the Aster 5000 20 ft container (5.016 MWh, 2.5 MW at 0.5 P). Newer products use 314 Ah LFP cells; the cell supplier is not named. Fire protection combines aerosol, sprinkler and gas/smoke/heat detection; larger units add venting or explosion relief panels. Datasheets (2 pages each) are downloadable per product and cite IEC 62619, IEC 62477, IEC 61000, UL 9540A, and UL 1973 on the DC blocks.

Photo policy
AlphaESS publishes no image licence or press kit, so model cards show a schematic illustration instead of a manufacturer photo. Photos will be added only with written permission.
No press-kit or media-asset page found on alphaess.com (only /news, /brochure, /document); product images served from /Public/Uploads without stated usage terms.
