The American-style energy storage converter step-up integrated machine is a highly integrated solution that converts solar, wind and other renewable green energy into electrical energy for storage in battery systems. When required, it inverts the stored energy through the integrated PCS (Power Conversion System) and delivers it to the three-phase AC step-up transformer, effectively solving the instability and periodicity issues of wind and photovoltaic power generation.
This all-in-one unit integrates the energy storage converter (PCS), busbar bridge, low-voltage compartment (for communication and power distribution), oil-immersed transformer (equipped with oil-immersed load switch and fuse), high-voltage cable compartment and a robust enclosure into a single compact package. As a turnkey pre-assembled energy storage station, it streamlines project implementation and reduces on-site complexity for commercial clients and utility operators.
Small footprint and compact structure, significantly reducing land acquisition costs for energy storage projects
All components are pre-integrated in a single enclosure, eliminating the need for separate PCS and transformer installation
Fully manufactured, assembled, wired and tested in our factory
Delivered as a complete prefabricated unit to project sites, enabling simple installation, reduced civil engineering costs and shortened construction cycles
Fast power supply and easy maintenance, requiring no on-site dedicated personnel for daily operation
Equipped with oil-immersed transformer energy storage system, offering high cost-effectiveness, excellent heat dissipation and low noise levels
Enclosure treated with special anti-corrosion and anti-UV processes, effectively resisting sand erosion and harsh outdoor environments
High-voltage side adopts oil-immersed load switch and full-range fuse protection scheme, ensuring safe and reliable operation with easy maintenance
