SUNNY TOWER

SMA presents the best in commercial inverter solutions: The Sunny Tower.

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.
