SMA Expands Large-Scale Storage Solutions with the Launch of Sunny Central Storage UP-S Inverter in Europe and the US

Staying competitive as an operator of large-scale storage systems in the rapidly evolving energy market: SMA Solar Technology AG (SMA) expands its large-scale storage solutions portfolio with the new Sunny Central Storage UP-S battery inverter. Featuring silicon carbide (SiC) MOSFET* technology, it offers superior power conversion efficiency and grid-forming capabilities for large-scale energy storage projects. Following a successful launch in Australia, this innovative SMA solution is now available across Europe and the US.

Joshua Birmingham, Head of Sales & Markets – Large Scale at SMA, stated that the company’s storage solutions enhance system performance and support grid stabilization, playing a crucial role in building a more resilient and sustainable energy future. Since the launch of the Sunny Central Storage 4600 UP-S in Australia, it has garnered significant interest from customers. SMA is now excited to introduce the battery inverter in Europe and the US. By combining advanced grid-forming capabilities with high efficiency, the solutions help utilities remain competitive and accelerate the energy transition.

Future-proof SiC MOSFET technology delivers efficient power conversion

At the core of the Sunny Central Storage UP-S is its advanced SiC MOSFET semiconductor stack, which delivers superior power conversion efficiency, drastically reduced thermal loads, and the ability to operate at full capacity even during grid-forming operations. These innovations translate to higher power output and increased profitability for developers and power plant operators, while also minimizing infrastructure and maintenance costs.

Key features of the Sunny Central Storage UP-S include:

• Up to 4,600 kVA continuously with short-term overload capability for dynamic grid.
• Over 99% efficiency thanks to innovative SiC MOSFET technology.
• Fewer inverters needed, reducing capital expenditure, installation, and maintenance costs.
• Optimized thermal management in any environment with the OptiCool™ air cooling system.
• Inverter-based inertia & improved short-circuit ratios to ensure stable power delivery during critical disturbances.
• Reduced harmonic values suitable for the most difficult grid conditions.
• Enables rapid, decentralized grid restoration, safeguarding the energy supply during outages.
