Designed specifically for installers, the Sunny Tower provides ease of installation,
lowest specific cost ($/Watt) and the highest efficiency to maximize rebates and power
production, while minimizing the overall payback period.

The Sunny Tower combines the performance advantages of string inverters with the
installation advantages of central inverters.  Because of Sunny Tower’s modular
design, it can be installed without the use of heavy equipment.  This allows any
installer with residential experience to successfully install commercial grade systems
using the experience and tools they already have.

The Sunny Tower is available in 36 kW and 42 kW models and multiple Sunny Towers
can be used together on a single system. Sunny Towers are available with a built-in
Sunny Web- Box making them internet ready.  The Sunny Tower places commercial
installations within easy reach of any installer while providing the performance and
reliability you’ve come to expect from SMA.
