There is a growing trend in the US and other major markets to adopt higher-voltage PV utility-scale systems, which enable longer strings and allow for fewer combiner boxes, less wiring and trenching, and therefore less overall components and installation time, reducing BOM (Balance of System) costs and lowering the LCOE (Levelized Cost of Electricity).
Solution
With an output of up to 2750 kVA and system voltage of 1000VDC or 1500 VDC, SMA's central inverters allow for more efficient system design. An integrated transformer and additional space is available for the installation of customer equipment. The Sunny Central is the central component of SMA Utility Power Systems. In combination with the medium-voltage block, DC technology, power plant controlling system and SMA Service, it is also available as compact platform solution. Utilizing SMA’s field-proven central inverter technology with minor component changes, this solution will result in higher power yields and lower specific costs. With superior stack design, the Sunny Central 2750-EV-US offers 1,500V technology for maximum reliability.
Applications
1,500V PV power plants.
Platform
The Sunny Central has been optimized for outdoor installation. The air cooling system ‘OptiCool’ ensures smooth operation, even in extreme ambient temperatures creating additional OPEX savings and contributing to the lowest cost of ownership in utility-scale PV. Sand and dust particles are effectively kept away.
