Founded in 2015, Nanjing Fudu is a core subsidiary of Green Holdings and its sole integrated facility for design, production, testing, and service, specializing in power system equipment and photovoltaic energy storage devices.

Nanjing Fudu’s independently developed products—including portable energy storage systems, vehicle-mounted energy storage systems, solar-storage-diesel smart energy cabins, and foldable photovoltaic energy storage systems—have gained strong client interest, with rapid business growth. Backed by over a decade of experience, it holds ISO9001 certification, with two production bases (Nanjing, Chuzhou) and one Nanjing R&D center, supported by four functional centers (Project, Engineering, Design, Chuzhou Experimental) for stringent quality control.

Committed to global green new energy’s photovoltaic and energy storage sectors, Nanjing Fudu delivers tailored integrated energy storage solutions for commercial/industrial applications, driving worldwide sustainable energy transition.
