SMA Sunny Island X-US > 60,000 Watt 480 VAC Hybrid Commercial Inverter | SI60-US480-20
The Next Generation Battery Inverter – more powerful than ever
The highly versatile Sunny Island X-US battery inverter
supports a wide range of on-grid installations.
As the central component of your energy system, the Sunny
Island X-US ensures that self-generated solar power is stored
and available whenever it’s needed. Engineered for maximum
flexibility and reliability, it performs consistently across extreme
environments, including desert heat, tropical humidity, and snowy
conditions, due to its broad operating temperature range.
With integrated energy management, the Sunny Island X-US
keeps your system running, even in critical situations. Built as a
highly robust battery inverter, it’s designed for long-term performance
and is backed by a warranty of up to 10 years ((5 years standard + 5 years
extended*)
