Up to 1MWh 500V~800V Battery
Energy Storage System
For Peak Shaving Applications
5 Year Factory Warranty
The 1MWh Energy Storage System consists of a Battery Pack, a Battery Management System (BMS), and an AC Power Conversion System (PCS).
We can tailor-make a peak shaving system in any Kilowatt range above 250 kW per module.
For applications over 1MW these units can be paralleled.
