Sunny Boy 1200

Sunny Boy 1200

Thanks to its galvanic isolation, The Sunny Boy 1200 is one from the series of universally applicable string inverters that can be used in the most diverse AC grids. The installation is made simple and easy using the integrated ESS DC switch-disconnector, thus, reducing the assembly costs. It is equipped with OptiTrac MPP-tracking process, and works well even under extreme conditions.
