3.FGI energy storage converter booster machine
10kV/35kV energy storage converter booster is a new type of energy storage integrated equipment exclusively developed after the deep integration of traditional energy storage converters and transformers. As the latest generation of energy storage converter products, it plays a vital role in all aspects of "source network charge and storage" and is a key equipment for building energy storage systems.
FGI electronic energy storage converter booster machine has the following significant features:
(1)High efficiency conversion
Using three-level topology, the maximum efficiency can reach 99%, and the efficient energy conversion is realized.
Intelligent air cooling system, even in 45 degrees of high temperature environment can ensure that the equipment does not derate operation.
Wide DC operating voltage range, stable operation at 1500V full load.
(2)Grid support
With the function of one-time frequency modulation, it can quickly respond to the dispatching demand of the source network load and storage, and provide strong support for the stable operation of the power grid.
(3）Grid support
With the function of one-time frequency modulation, it can quickly respond to the dispatching demand of the source network load and storage, and provide strong support for the stable operation of the power grid.
