The Hua-Style Energy Storage Converter Step-Up Integrated Unit is used in renewable energy storage systems for solar power, wind power and other green energy applications. It stores converted renewable energy in the battery system and outputs the power through the PCS when needed, sending it to the three-phase AC step-up transformer.
By integrating the PCS, busbar bridge, low-voltage compartment, oil-immersed transformer, high-voltage compartment and enclosure into one compact unit, the product helps simplify equipment arrangement and on-site installation. It is suitable for energy storage projects that require power conversion, voltage boosting, communication and power distribution, high-voltage protection and integrated outdoor installation.
The unit has a small size, compact structure and high level of integration. The integrated design helps reduce floor space and makes the overall system layout more compact.
Manufacturing, assembly, wiring and debugging are completed in the factory. The unit can be transported to the project site as a box-type integrated system, reducing on-site assembly workload.
The integrated structure makes installation easier, helps save basic construction costs and shortens the construction period. It also supports fast power supply deployment, convenient maintenance and operation without dedicated on-site attendance.
The unit adopts an oil-immersed transformer with good cost performance, effective heat dissipation and low operating noise, supporting stable operation of the energy storage step-up system.
The enclosure adopts special surface treatment technology, providing good corrosion resistance and UV resistance. It can also help resist wind and sand erosion in outdoor applications.
The high-voltage side adopts a vacuum load switch or circuit breaker. It supports remote operation and provides comprehensive protection for the integrated energy storage converter step-up system.
