SMA’s most powerful system with an output power of up to 4,600 kVA for large-scale 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.
