Sineng Electric Showcases Next-Generation PV + ESS Solutions at RE+ 2025

Sineng Electric made a strong presence at RE+ 2025, the premier solar and energy storage exhibition in Las Vegas, unveiling its next-generation PV+ESS solutions. With a focus on innovation and system-level integration, Sineng is empowering the global energy transition and delivering advanced technologies that meet the evolving needs of customers and partners worldwide.

Pioneering Energy Storage Solutions

As a leader in 6MW+ energy storage solutions, Sineng presented four scenario-based offerings: BESS solution for Renewable energy integration, stand-alone BESS solution, C&I BESS solution, and microgrid BESS solution. Covering both string and central PCS technology routes, all systems are equipped with Sineng’s next-generation enhanced grid-forming technology, providing robust support for large-scale renewable integration and ensuring the stable operation of new power systems.

• 6.88MW String PCS MV Turnkey Station: Featuring 430kW string PCS, this system leverages low-power-consumption liquid cooling and an optimized power drive control algorithm, achieving a 0.2% boost in round-trip efficiency and 30% lower auxiliary consumption. Its cluster-level management and intelligent balancing control deliver 7% higher charging/discharging yield, while cutting O&M costs by 50%.
• 6.9MW Central PCS MV Turnkey Station: Built with 1725kW central PCS, this flexible platform supports 1/2/4/6/8-hour system configurations and matches 6MWh+ DC input. Its passive liquid cooling improves heat dissipation efficiency by 15% and reduces maintenance costs by 30%. The foundation-free design lowers construction costs, while modular replacement ensures a system availability rate of over 99%.

Innovations in Utility-Scale PV Inverters

In addition to storage, Sineng highlighted its flagship PV inverters:

• 465kW String Inverter: High power density design, compatible with larger arrays, reducing installation and transportation costs. Integrated with arc detection 2.0, active airflow health monitoring with reverse dust removal, and AC/DC grounding fault detection, it ensures safer and more efficient solar power generation.
• 4.8MW MV Turnkey Station: Featuring zonal intelligent thermal management, it significantly extends component lifetime. The modular design enables IGBT replacement within 30 minutes, boosting O&M efficiency. Its microsecond-level wave recording function allows precise fault localization.

Driving the Future of Clean Energy

By redefining industry benchmarks with cutting-edge PV and storage technologies, Sineng Electric is shaping the future of clean energy. With China as its foundation and a global vision, Sineng continues to work hand-in-hand with partners worldwide to accelerate the transition toward an intelligent, efficient, and resilient energy system.
