350kW/350kWh Construction Site Backup Energy Storage Solution

The construction site backup energy storage solution employs adopts liquid-cooled battery PACK + liquid-cooled PCS design, which has good heat dissipation effect. It supports long-term 1C rate discharging to meet the needs of impact load scenarios. The system’s internal PCS high-frequency transformer is isolated, and no additional isolation transformer is required; it supports the access or output of new energy such as diesel generators and photovoltaics, and can be used in harsh environmental scenarios such as factories and construction sites, providing power support for impact loads such as mixers and air compressors, and providing electricity or backup power needs for industry and commerce, construction sites, and users without electricity or weak electricity.
