SMA Sunny Island X 50 with Dyness Stack 100 – 76.8 kWh
This high-performance system package combines the Dyness Stack100 high-voltage storage unit, with a usable capacity of 72.96 kWh, with the SMA Sunny Island X 50, one of the most robust and versatile next-generation battery Inverters. The Stack 100 stands out thanks to its stackable design with plug-and-play installation, an integrated aerosol fire suppression system, an integrated heating function and a service life of over 8,000 cycles – making it ideal for demanding on-grid and off-grid applications in the commercial and industrial sectors. The SMA Sunny Island X 50 complements the system as the central battery Inverter, offering 50 kW of output power, an integrated DC-DC converter and intelligent energy and load management for reliable operation even under the most extreme conditions. Together, these two components form a scalable, future-proof energy storage system with comprehensive system monitoring via Sunny Portal powered by ennexOS.
Final approval from SMA is still pending!
An STACK100 tower can officially accommodate up to 15 modules; however, for 12 modules or more, Dyness recommends the expansion/auxiliary tower kit to ensure safe installation and cable routing.
