UTILITY POWER SYSTEM
Optimized DC-TO-AC Solution for Utility Scale PV
Unveiling of the new SMA Utility Power System
With the highly-anticipated unveiling at Intersolar Europe 2014, the SMA Utility Power System stole the show as SMA's newest solution offering reduced OPEX, reduced CAPEX and maximized energy production.
With a Sunny Central inverter at its core, the Utility Power System is an integrated, compact DC-to-AC system solution for utility-scale PV power plants. Available in IEC and ANSI versions, the system is well suited for worldwide implementation.
A comprehensive, engineered solution
The SMA Utility Power System expands the features of PV power plants with precisely synchronized components - the new Sunny Central inverter, medium-voltage transformer, DC combiners, corresponding plant control with vital project support and world-class service.
Designed for use outdoors in all regions of the world, the SMA Utility Power System enables grid stability and ancillary services on a global scale. It simultaneously delivers the highest yields with low operational costs for the life of the PV plant.
At the heart of the Utility Power System

Ready for future grid stabilization
Great demands are being placed on PV systems to behave like conventional power plants. This makes grid stability and ancillary services crucial, especially in many regions of the world where the power grid infrastructure is not well developed.
SMA's new DC-to-AC system solution will enable PV power plants to fulfill worldwide grid regulations by providing all ancillary services including full “Q on demand” (24/7) reactive power capability. The Utility Power System allows PV plants to become adaptable to grid requirements and eliminate or minimize expensive power grid extension, especially in remote areas of the world and regions with underdeveloped infrastructure.
Built to withstand harsh environments
PV power plants are built across the globe, including areas of high altitude, extreme temperature, proximity to the sea, and desert areas impacted by sand and dust. SMA inverters and system solutions are designed to deliver the highest outputs anywhere. OptiCool™, a field-proven cooling technology, enables maximum efficiency for the Sunny Central even at the highest temperatures. With a precision air cooling, dust and sand particles cannot affect the inside of the inverter.
The next generation of SMA system solutions is not limited by environmental conditions and can be implemented in all large-scale PV projects. SMA regularly subjects its inverters and system components to demanding tests simulating the harshest conditions to ensure that SMA products can exceed expectations in even the most demanding applications.
