Powering the Next Wave of Renewables: Inside Sineng's Advanced Energy Storage Solutions image

As the global transition toward renewable energy accelerates, energy storage has emerged as a cornerstone of sustainable power systems. With projections showing cumulative global capacity reaching 1,722 GW/6,214 GWh by 2035, the demand for effective storage solutions is surging. However, the industry still faces key challenges, including high initial costs, efficiency concerns, and scalability constraints.

Leveraging its extensive expertise in power electronics, Sineng Electric is developing transformative solutions to overcome these barriers, from high-power utility-scale systems to smart residential batteries.

Scaling Up: The Shift to High-Power 12.5 MW Systems

At the utility scale, Sineng is leading the transition to 12.5 MW energy storage systems. These high power solutions are designed to meet the growing need for grid stability and power fluctuation mitigation.

  • Enhanced Energy Density: The systems deliver more energy throughput within a smaller physical footprint.
  • Improved Efficiency: High power Power Conversion Systems (PCS) significantly reduce conversion losses, resulting in improved round trip efficiency and optimized use of stored energy.
  • Lower Costs: By requiring fewer PCS units to achieve the same total capacity, the systems reduce equipment, installation, and maintenance costs.

Cool Under Pressure: The Liquid Cooling Advantage

Liquid cooling technology has become a significant differentiator among leading energy storage manufacturers. Sineng Electric has embraced this innovative approach to enhance heat dissipation and enable higher power density.

  • Optimal Thermal Management: The new generation 430 kW string PCS, equipped with liquid cooling, effectively reduces temperature fluctuations. It maintains a consistent IGBT temperature differential of less than 3°C, ensuring stable power output.
  • Extended Lifespan: This advanced thermal management extends the system's lifespan to over 25 years.
  • Reduced Maintenance and Noise: Compared to traditional air-cooled systems, Sineng Electric's liquid cooled PCS operates with minimal noise and eliminates the need for frequent filter replacements, significantly lowering maintenance costs.
  • Easy Installation: An IP68 rated quick plug terminal facilitates effortless plug-and-play installation, while a self-sealing plug ensures zero leakage.

Creating a Smarter, More Resilient Grid with Grid-Forming Technology

As renewable energy penetration increases, grid forming energy storage has become fundamental for ensuring system stability. Unlike traditional generators, renewable sources lack inherent stabilizing properties. Grid forming storage bridges this gap by functioning as a "virtual synchronous machine," autonomously regulating frequency and voltage. In the event of a blackout, it also provides black start capabilities, enabling the grid to recover independently.

To address this, Sineng Electric has developed advanced control algorithms and widely deployed its 1.25 MW central PCS with the latest virtual synchronous generator (VSG) technology. This has been demonstrated in a 200 MWh microgrid BESS project in Xinjiang, China, which uses 20 units of Sineng's 2.5 MW central PCS MV turnkey stations.

Empowering Homes: The Future of Residential Energy Independence

As homeowners increasingly seek energy independence and a zero-carbon lifestyle, Sineng Electric offers a comprehensive range of home energy storage systems.

  • Advanced Battery Technology: The household battery pack features automotive-grade, high capacity batteries and eliminates the "barrel effect," enabling the mixed use of new and old cells.
  • Flexible and User-Friendly Design: Its modular design supports scalable configurations from 6.4 kWh to 25.7 kWh and features a plug-and-play design for streamlined installation.
  • Durability and Safety: The battery is built for exceptional durability with an IP65 protection rating and a service life exceeding 10 years. A multilayered safety system ensures maximum protection, incorporating millisecond-level intelligent fire response.
  • Smart Management: When paired with the smart energy management platform EnjoySolar, homeowners can gain full visibility and control over their entire home energy system.

Through continuous innovation, Sineng Electric is setting new benchmarks in modern energy storage, from pioneering high-power, liquid cooled technologies to advancing grid forming capabilities and residential solutions.
