Low-voltage Residential ESS


C&D EMERGING ENERGY provides diversified options for residential lithium battery energy storage. Make your Home Green with C&D Batteries just connect your existing Photovoltaic System or install a new one with a Hybrid inverter to be immediately energy independent.







C&D EMERGING ENERGY's energy storage systems provide energy storage and output management in power generation. The electrochemical technology and renewable energy power generation technology form a joint system. Through the high-level consistency of cells and the powerful computing of BMS, C&D EMERGING ENERGY enables the power generation to restore a stable power grid, optimize the power output curve, reduce solar and wind curtailment, provide system inertia and the functions of frequency and peak modulation, increase the proportion of renewable energy in total power generation, and optimize the energy structure.







- BMS with self ID capability.


- Wall mounted, floor mounted, stackable, for parallel application.


- High capacity thanks to expandible and simple configuration.


- Wireless monitoring for real time and mainteinance.
