SMA America Expands Large-Scale Storage Portfolio with Advanced Battery Inverter

Mar 22, 2025

SMA America has introduced the Sunny Central Storage UP-S battery inverter to the U.S. market, following its successful deployment in Australia. Designed for large-scale energy storage projects, the inverter incorporates silicon carbide (SiC) MOSFET technology, enabling high power conversion efficiency and advanced grid-forming capabilities.

Key Features:
  • High Efficiency: Over 99.2?ficiency with SiC MOSFET technology, reducing energy losses and improving overall system performance.
  • Maximum Power Output: Delivers up to 4,600 kVA without power derating at 35°C (95°F).
  • Cost Reduction: Higher efficiency lowers battery capacity requirements, reducing CAPEX on inverters and batteries while enhancing energy yield.
  • Grid Stability: Provides dynamic grid support, robust fault ride-through capability, and optimized thermal management with OptiCool™ air cooling.
  • Advanced Grid-Forming Capabilities: Includes inverter-based inertia, improved short-circuit ratios, and overload capability for grid-forming applications.
  • Grid Resilience: Minimizes harmonic emissions for better grid compatibility and supports rapid, decentralized grid restoration during outages.

With large-scale energy storage becoming crucial for grid modernization, SMA America's latest offering aims to help utilities and developers improve efficiency, enhance grid resilience, and lower project costs.
