The 7.15MW grid-following centralized PCS integrated energy storage unit is a core power conversion and control device designed exclusively for utility-scale energy storage power stations. Adopting a highly integrated design philosophy, it seamlessly integrates energy storage converters, power transformers and electrical protection units into a single cabin. This all-in-one solution can be directly connected to medium and high voltage power grids, enabling efficient bidirectional energy conversion between battery packs and the grid with strict grid-following characteristics that precisely match grid parameters. It is the ideal choice for project developers and operators seeking reliable, cost-effective and space-saving energy storage solutions.
Our integrated PCS transformer unit features a triple three-dimensional layout within a single cabin, reducing equipment volume by 60% and saving 30% of construction land compared to traditional split systems. This is particularly valuable for projects in areas with scarce land resources, significantly lowering land acquisition and site preparation costs.
Housed in a robust containerized structure with IP54 protection rating, the unit delivers exceptional resistance to earthquakes (up to magnitude 8) and salt spray corrosion. It ensures stable 24/7 operation even in extreme weather conditions, minimizing downtime and maintenance expenses for long-term project profitability.
All internal connections and comprehensive pre-commissioning are completed at the factory before delivery. This eliminates complex on-site assembly work, shortening the overall construction period by 40%. Project owners can bring their energy storage systems online much faster, accelerating revenue generation and return on investment.
Equipped with an advanced intelligent control system, the unit supports real-time remote monitoring, automatic fault diagnosis and partial power-off maintenance. This significantly improves operational efficiency, reduces on-site labor requirements and ensures optimal system performance throughout its service life.
