Can you briefly highlight the key features of the 215kW String, 2MW, and 1725kW Central PCS?
Sineng recognizes that developing Energy Storage Systems (ESS) is crucial for grid stability and maximizing RE use. To address these needs, Sineng has been providing central and string PCS (Power Conversion System) with the strong momentum of the innovation. In India market, Sineng is offering string PCS 215kW and central PCS 2MW and 1.725MW, complying with IEC and other standards. These products cater to diverse application scenarios and project specification.
Grid-Forming Capabilities: The PCS integrates synthetic inertia, frequency response, VSG functionality, SVG support, enhanced short-circuit capacity and black start capabilities which enable PCS for rapid, autonomous grid restoration and improved grid resilience.
Advanced Grid Support: The PCS can withstand 1.2× rated current for 2 minutes, and provides up to 110% overload power, enhancing its robustness in managing grid instability and fault ride-through scenarios.
Scalable Parallel Operation: Central PCS support 4 unit in parallel mode and String PCS support 24 units in parallel mode. This scalability makes central and string both PCS perfect for any project size and hour rating system, from microgrid to utility scale application.
Diversified Working Modes: The central and string PCS support programmable working modes, allowing customization for specific needs such as grid forming, grid following, off grid and droop. This adaptability ensures optimal performance across diverse use cases, from large-scale grid support to remote off-grid communities.
Robust Design: Central PCS features IP65 protection, C4 anticorrosion and operating temperature range from -40°C to +60°C. String PCS features IP66 protection, C5 anticorrosion and operating temperature range from -40°C to +60°C. Engineered for extreme operational conditions, the both PCS operates at a low noise level of dB(A), making it suitable for coastal and dust-prone environments.
Advanced Safety Measures: To mitigate potential risks associated with short circuits, the PCS limits short-circuit, effectively preventing cascading failures and enhancing operational safety. Central PCS is equipped with fuse plus LBS on DC side and ACB on the AC side. String PCS is equipped with MSD plus fuse on DC side and breaker on the AC side. Both type of PCS have over temperature protection, lightening protection and other safety measures.
Enhanced Efficiency: By integrating 2 phase cooling technology and an optimized power control algorithm, central PCS improves its round-trip efficiency (RTE) while reducing auxiliary power consumption. String PCS’s rack-level management increases system charge and discharge capacity by over 7% throughout its lifecycle, thereby maximizing the operational cost-effectiveness.
How are these PCS models suited for India’s solar needs, especially in South India?
Sineng tailor-made solutions and its PCS model supports Solar needs in various ways:
Black Start Capability: Sineng PCS is equipped with Black Start capability, enabling it to support grid recovery during a blackout. This feature allows PCS to maintain grid stability and supply essential loads without relying on the external grid.
Efficient: It reduces energy waste by storing excess energy and releasing it when demand is high or generation is low.” Also supports Voltage/frequency regulation, Seamless transition between grid-connected and off-grid modes & Uninterrupted power supply (UPS functionality).
Reliable: It ensures a dependable energy supply, particularly in regions with weak grid infrastructure or frequent power outages. It also supports the development and strengthening of micro-grids. It enables peak shaving and load shifting, Store excess solar for use during peak demand (e.g., evening).
Low BOS (Balance of System): Sineng PCS (Power Conversion Systems) 215kW String PCS, 2MW Central PCS and 1725kW Central PCS are compatible with various types of foundations and offer high power density with a smaller footprint. This reduces the initial investment required for energy storage power stations by lowering BOS costs. Also it helps charging batteries during low-tariff hours & discharging during high-tariff periods to reduce grid draw.
What unique technologies set your new PCS products apart from others in the market?
Sineng PCS adopts enhanced hybrid grid-forming technology, supporting all-scenario applications. Its certified 1250kW central PCS features ten core grid-forming functions (e.g., inertia response, voltage reconstruction). Its 430kW liquid-cooled string PCS pairs with 600+Ah battery cells, achieving 91% round-trip efficiency and significantly lowering LCOS.
How do these PCS systems improve grid integration, efficiency, and project reliability?
Sineng PCS is set to revolutionize the energy storage landscape in India with its pioneering technology not only enhances efficiency and grid support, but also significantly reduces both capital and operational expenditure costs. More RE projects come into operation, more resources are added to the energy mix. Hence, it is even more important to maintain grid stability and improve power quality. With a proven track record, Sineng performance remains unparalleled in Chinese and overseas markets.
What’s Sineng’s strategy to grow PCS adoption in India, and what role will South India play?
Sineng Electric is positioning itself as a key player in India’s energy transition by aligning its strategy with the country’s ambitious to the Battery Energy Storage System (BESS) goals.
Make in India Commitment
Sineng has embraced the Make in India initiative as a cornerstone of its expansion strategy. It established its first overseas manufacturing base in Bangalore, which now boasts a 15 GW annual capacity. This local presence enables faster deployment, cost-effective solutions, and alignment with government incentives for domestic manufacturing.
Technology Innovation & Product Localization
Sineng focuses on tailor-made solutions for India’s unique grid and climate conditions. Our PCS inverter technologies are already widely adopted, and BESS integration is a natural next step. By investing in R&D and adapting products to local needs, Sineng aims to support round-the-clock renewable energy systems.
Partnerships & Ecosystem Development
We partner with our existing IPP & EPC to penetrate and build this giga projects for the PCS which will help to transform various govt BESS Consortium into reality. Sineng’s growing influence in India’s solar sector positions it well to collaborate with DISCOMs, developers, and regulators on BESS projects.
Sustainability & Net-Zero Alignment
India’s goal of deploying 47 GW of BESS by 2032 and achieving net-zero by 2070 creates a massive opportunity. Sineng’s strategy is aligned with these national targets, focusing on enabling grid stability, energy resilience, and carbon reduction through integrated renewable solutions.
