Product Description
This 1MW/2MWh system is a highly integrated, megawatt-scale containerized energy storage solution designed for C&I and small-to-medium utility sites. It comes pre-integrated with a high-efficiency PCS, LFP battery packs, MV isolation transformer, thermal management, fire protection, and an energy management system.
Adopting a true "turnkey" concept, the system is factory pre-commissioned and delivered as a whole unit, significantly reducing on-site installation time and labor costs. It supports both grid-tied and off-grid modes, providing services like peak shaving, demand management, dynamic reactive power support, and emergency backup to enhance grid stability and reduce electricity costs.
