The 20-ft and 40HQ liquid-cooled ESS container integrates PACK, EMS, BMS, HVAC, and fire safety system into one cabinet. Compared with air cooling, liquid cooling empowers the ESS product with higher power density and ensures the temperature difference between the cells within 3 ºC, which effectively extends battery service life and improves energy efficiency. The 20-ft liquid-cooled ESS container product can be applied to the power generation side, grid side, as well as C&I ESS scenarios that have strict requirements on power and capacity.

In order to reduce the production losses caused by power outages in summer, high-energy-density ESS solution has been introduced. The DC side consists of lithium battery energy units, and the AC side uses MEGA series PCS. Through the EMS operation strategy, it interacts with the grid in a friendly way, and provides power support for customers during power limited periods.
The energy storage standard battery module consists of 16 units 3.2V single cell, each unit battery power is 14.336kWh, the nominal voltage is 51.2V, totally 2MWh, 1600kWh@80% DOD. Battery energy usually customized according to each client's exact requirements, from kWh to MWh or GWh.
Our containerised energy storage system (BESS) is the perfect solution for large-scale energy storage projects. The energy storage containers can be used in the integration of various storage technologies and for different purposes.







Focusing on the production, R&D and design of solar panels, inverters, batteries, and complete energy storage systems (including C&I ESS, BESS, and home solar systems).
