About Kehua Digital Energy
Kehua Digital Energy is the PV and energy-storage arm of Kehua Tech (Kehua Data Co., Ltd., founded 1988), headquartered in Xiamen. Its core competence is power conversion: the company sells a large range of BCS-series PCS from 75 kW modular units to 13.8 MW MV skids and reports cumulative energy-storage installations above 53 GW. It does not manufacture cells and does not name its cell suppliers; the S³-EStation 5 MWh datasheet only states LFP-class 314 Ah cells in a 12P416S arrangement. The battery portfolio is small: S³-EStation 5 MWh (SR12-P4104S1PL314BG, liquid-cooled 20ft DC container, 0.5P and 0.25P versions, hot-aerosol suppression, IP55, IEEE 693 seismic), the older S³-EStation 3.44 MWh (280 Ah, IEC 62619 / EN 62477-1 compliance) and the S³-EStore C&I cabinet (100 kW AC with integrated PCS, 215 or 241 kWh). Utility projects are typically delivered as S³-EStation containers plus a separate Kehua MV PCS skid (marketed as S³-EStation 2.0, 5 MW/10 MWh blocks). Not published: system power ratings for the containers, cycle life, calendar life, warranty, round-trip efficiency at system level, weight of the C&I cabinet's PCS, and any UL 9540/9540A listing. Product images are hot-link protected and no press-kit licence is stated.
