Energy storage converter booster integrated machine (American Style)

Our company’s independently developed three point flat medium voltage high-power energy storage converter, switchgear, and step-up transformer have been optimized and integrated. They have the characteristics of higher power per set of equipment, simple application, flexible installation site selection, and convenient operation and maintenance. The system can directly connect 10/35kV high voltage to the power grid, reducing complex high voltage system design work, shortening the system design cycle, and reducing system design costs.
