Huawei Digital Power

Huawei Digital Power Technologies, a Huawei subsidiary headquartered in Shenzhen, sells stationary storage under the FusionSolar / LUNA2000 brand. Its utility-scale products are 20 ft DC battery containers built on a 'smart string' architecture (pack-level DC/DC optimisation): the liquid-cooled LUNA2000-5015-2S (5,015 kWh, 2,507.5 kW at 0.5 CP, 314 Ah cells) launched at Intersolar Europe 2025, the earlier LUNA2000-4472-2S / 4.5MWH-2H1 (280 Ah), and air-cooled 2.0MWH and 1.0MWH containers that remain on regional pages. Power conversion is external, via LUNA2000-213KTL-H0 / 200KTL string PCS and Smart Transformer Stations, so containers are DC blocks. In C&I, the LUNA2000-241-2S1 (241 kWh, 314 Ah, hybrid liquid/air cooling) and its predecessor LUNA2000-215-2S10 integrate a 108 kW PCS. All datasheets state LFP chemistry but Huawei does not name the cell supplier. Datasheets list UL 9540A, IEC 62619, IEC 62933-5-2, UN 38.3 and IEC 62477-1 among others; UL 9540 system listing is not shown. Cycle life, warranty terms, round-trip efficiency for utility containers and calendar life are not published; C&I sheets give 91.3% maximum cycle efficiency. Regional datasheet versions (EU/APAC/MEA/JP/CN) differ slightly. A next-generation platform, LUTERRA (1,000 Vac string architecture, 12.5 MW/50 MWh arrays), was announced in June 2026 without a container datasheet.
