Rack Battery and ESS English Product Catalogue
The displayed 20-GP and 40-GP rated energy, 768V voltage basis, air-cooling method and communication protocols follow the English ESS catalogue.
Final container configuration, fire-protection scheme, compliance package and logistics scope require project-specific confirmation.
The full catalogue is provided for qualified project discussions because the current source file is a large system document.
Quotation confirmation
Provide destination market, required capacity and system application so our team can confirm the matched model, brand scope and supporting documentation.
