SMA Sunny Boy Storage


Inverter designed for high-voltage batteries for domestic use. Sunny Boy Storage allows economic integration, simple and flexible storage solutions for photovoltaic systems both new and existing.

  • 97% efficiency
  • WLAN and intuitive web interface
  • Compatible with high-voltage lithium-ion batteries
  • For new and existing systems

It is simple and flexible

The new inverter with Sunny Boy SMA Storage battery was developed specifically for high-voltage batteries, as powerwall Tesla.
The combined solution consisting of battery and Sunny Boy Storage allows the accumulation of electricity at costs that are comparable to the prices for domestic electricity.

Economic Integration

– SMA inverters are compatible with all leading storage technologies in the market
– Suitable for photovoltaic plants of any power class, from residential systems to PV power plants
– Optimum integration thanks to standardized interfaces
– Built-in monitoring for control consumption you can be displayed using an app the energy flows and savings opportunities

Also for existing plants

The Sunny Boy Storage helps to make your home less dependent on electric utility companies and allows you to use at night the electricity produced during the day.
SMA is the only company that offers a system with alternating current connection for high voltage batteries, which works in parallel with the photovoltaic system.
This allows installation on existing systems, but also a subsequent flexible expansion of the system with reduced cost and without complications as it is not necessary to intervene photovoltaic system.
