Technology matters when it comes to extreme oversizing: The Sunny Central inverters from SMA are designed for maximum oversizing capabilities. PV power plant projects with SMA central inverters profit from more flexibility, reliability, technology safety and highest profitability.
With oversizing, the PV power plant’s nominal power is achieved faster in the morning, and the PV power plant remains connected to the grid longer in the evening. Calculated for the total operating time of the PV project, higher energy yields can thus be generated. Adequate oversizing increases the profitability of a PV power plant. The Sunny Central inverters from SMA with their robust design offer maximum flexibility for project-specific oversizing.
SMA takes the effect of short-term solar irradiation increase (mirror cloud effect) into account with an additional buffer in the oversizing capacity of the inverters. Thus, SMA inverters can still disconnect the PV array’s short-circuit current up to 6,400 A. This corresponds to an oversizing (peak PV array power in relation to the maximum AC inverter power) of up to 250%.
If you want to learn more about the mirror cloud effect, you can find all information in s´the SMA Whitepaper. (zu Whitepaper)
With Sunny Central inverters, developers have the opportunity to get the maximum efficiency out of their PV power plant through unrestricted oversizing capacity while maintaining the same life expectancy, availability and operating costs of the devices.
