On April 10th, 2025 ESIE Beijing Energy Storage Exhibition, Shenzhen Yuntian Digital Power Co., Ltd. made a stunning appearance with its star products and cutting - edge technologies. At the Beijing exhibition, Yuntian Digital Energy comprehensively demonstrated its strong R&D strength and market responsiveness in the field of industrial and commercial energy storage through popular themes such as three - phase four - leg and overseas PCS certification.

In the field of power conversion system (PCS), Shenzhen Yuntian Digital Power Co., Ltd. newly launched the high - protection three - phase four - leg Mars - 135KF - AP - B. Its power range is 125kW - 135kW, voltage range is 580V - 1000V, and it is compatible with the 280 - 320Ah battery system. It can maintain excellent performance in a variety of complex application scenarios.

Compared with the traditional air-cooled power conversion system (PCS) for energy storage, the three-phase four-leg PCS technology of Shenzhen Yuntian Digital Power Co., Ltd. has the following remarkable advantages:

Three - phase unbalance governance ability: The three - phase four - leg design can better realize the single - phase control function, support 100% unbalanced load - carrying, accurately adapt to the energy - storage application scenarios such as the distribution transformer area and micro - grid, govern the voltage unbalance, reduce the impact of non - linear loads on the system, and ensure the stable operation of the system.

IP66 high protection: This PCS has the IP66 high - protection level and can operate stably in harsh environments with high dust and high salt spray. Its fan speed can be automatically adjusted according to the temperature and output power to ensure the efficient operation of the equipment under harsh working conditions.

Integration of DC - side PDU function: It supports compatibility with mainstream BMS manufacturers, integrates the DC - side trip - circuit breaker and AC RCD (residual - current protection), and further enhances the safety and reliability of the product.

Versatility and wide adaptability: It supports single - phase and three - phase active and reactive power control and has a wider DC - voltage adaptation range, which greatly improves the flexibility and adaptability of the system.

Low - cost and high - efficiency: The three - phase four - leg PCS technology can realize 100% single - phase off - grid load - carrying without the need for additional transformers, which greatly reduces the cost of the overall energy - storage system and optimizes the space utilization rate.

Better power quality: It has built - in AC - and - DC - side EMI filters, which greatly reduce electromagnetic interference, optimize the output power quality of the product, and make it especially suitable for overseas export projects, enhancing the market competitiveness of the product.

vsG grid - forming control technology: It supports the grid - forming control technology, can provide primary frequency modulation and inertia support for the system, supports the multi - machine parallel circulating - current suppression algorithm, can realize flexible parallel connection, and is suitable for various grid - connected and off - grid applications.

The newly launched PCS technology of Shenzhen Yuntian Digital Power Co., Ltd. has achieved breakthroughs in the industry in multiple dimensions this time. By integrating the latest control algorithms and hardware designs, it enables the energy storage system to achieve an ideal balance among high efficiency, high reliability, and low cost.
