SMA Sunny Island X 50 with Dyness Stack 100 – 76.8 kWh
This high-performance system package combines the Dyness Stack 100 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 Stack100 impresses with its stackable design featuring 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!
