Step UP your expectations. Discover the next generation of PV power.

The Next Step UP. Sunny Central UP.

Sunny Central UP

Step UP your performance

SMA’s most powerful system with an output power of up to 4,600 kVA for Small-Scale Utility Solar PV and Large-Scale Utility Solar PV plants offers the advantage of 17% to 54% fewer inverters. With the Sunny Central UP, you benefit from significant cost reductions on transportation, installation, commissioning and service. In addition, reducing self-consumption by a total of 53% will lead to a considerable decrease in operation costs.

Separate voltage supply and additional space are available for the installation of customer equipment. True 1,500 V DC technology and our improved intelligent cooling system OptiCool™ ensure smooth operation even at extreme temperatures and with a service life of 25 years.
