Equipped with active/reactive four-quadrant regulation functionality, it can dynamically allocate power, flatten peak loads, and fill valleys—operating automatically on-site—to enhance grid stability and improve controllability. Additionally, it fully supports remote OTA upgrades, integrates multiple communication ports such as RS485 and CAN, and is compatible with protocols like Modbus-RTU and CAN2.0B, enabling smart interconnectivity and broad applicability across various industries.
Precise, stable, and reliably trustworthy
High-precision control and rapid response—delivering a power response time of less than 10ms, ensuring users a stable and reliable experience. Featuring a three-phase three-wire system suitable for off-grid applications, it supports multi-unit AC/DC parallel operation for flexible scalability. Compatible and mutually certified with multiple industry-leading BMS and EMS systems, this product also boasts robust LVRT/HVRT capabilities, enabling strong grid adaptability. In terms of safety protection, it incorporates an independent air duct design, achieving an IP65-rated enclosure and comprehensive electrical safeguards. Additionally, it is engineered to thrive in challenging environments, including high altitudes, extreme temperatures and humidity, as well as exposure to salt spray, sand, and dust.
Full-stack, independently developed breakthrough paves the way for a new milestone in efficient integration.
Equipped with a 215kW PCS, the 215kW/418kWh distributed liquid-cooled energy storage cabinet features a highly integrated design, offering a smaller footprint, higher energy density, and lower unit costs. It can be flexibly configured, freely combined, and swiftly delivered to meet users' specific application scenarios and capacity requirements. This 418kWh energy storage cabinet delivers AC output at 690V and supports multi-unit AC-side parallel expansion for increased capacity. Additionally, it can be locally stepped up via a transformer to connect seamlessly to either 10kV or 35kV grid systems. Compared to conventional systems of similar scale, this solution requires fewer equipment units—just 12 units are enough to fulfill a substantial 5MWh demand. Moreover, the coordinated operation among multiple units ensures enhanced consistency, while boosting the overall system efficiency. As a result, it stands out as the ideal choice for high-safety, large-capacity distributed energy storage power stations.
This 215kW PCS, combined with Cloud Energy's Cube-level Management Solution, provides users with a 5MW/10MWh energy storage system solution. The solution enables each individual PCS to independently connect to and manage the battery system, further enhancing battery utilization and system conversion efficiency. Moreover, maintenance on a single PCS or even an entire battery cluster will not disrupt the normal operation of other circuits. Additionally, the system can accommodate up to 24 clusters, each equipped with a 418kWh battery unit, significantly boosting the energy density of the storage system while effectively reducing overall system investment costs and shortening the project’s payback period.
Additionally, this 215kW PCS is perfectly tailored for the 5MW/10MWh containerized energy storage solution. Featuring an integrated design that combines high-voltage cabinets with PCS modules, the system seamlessly integrates a single PCS unit directly with a cluster of battery systems—allowing for compact, all-in-one installation within the energy storage container. Its modular design enables convenient installation and commissioning, while the inclusion of an AC busbar system and an external step-up box-type substation ensures rapid completion of installation, commissioning, and delivery for the energy storage project. This approach further helps users reduce both investment costs and construction timelines.
YunNeng Magic Cube continuously drives technological innovation, firmly committing to the independent research and development and production of core components, providing users with cutting-edge, reliable, and comprehensive solution applications—while partnering with collaborators to jointly fuel the robust growth of industrial and commercial energy storage.
