basic information
The large-scale energy storage system product "SUNNY CENTRAL STORAGE UP-XT" has previously offered the 4MW-class models "SCS3450UP-XT" and "SCS3950UP-XT." It features high output relative to the size of the PCS, is compatible with a wide range of battery manufacturers, and can flexibly accommodate various capacities. It also supports options for autonomous operation and grid-forming (inertia force PCS) implementation. The newly launched "SCS2300UP-XT" and "SCS2630UP-XT," now available for domestic sales, are 2MW-class products with smaller output, voltage range, and rated voltage. While the conventional 4MW-class products primarily target large-scale energy storage systems such as large power plants, the 2MW-class products cater to high-voltage demand. In environments where multiple units of existing low-output products from other companies were necessary, these can be consolidated into a single unit, making them suitable for a wide range of applications, including relatively large factories, plants, and logistics warehouses, where one or two units can be installed.
