Sunny Boy string inverters can each process the power from 6 - 24 modules- depending on inverter type.
Inverters automatically shut down in the event of : High-Low grid AC voltage, High/Low grid frequency, Grid failure; or Inverter malfunction. In PV applications the Sunny Boy inverters automatically adjust PV array loading to provide maximum efficiency of solar panels by means of a maximal power point tracker (MPPT).
The Best in their Class
One of the most important criteria when purchasing an inverter is its efficiency. The higher the efficiency, the lower the losses that are incurred when converting direct current produced by the solar modules into alternating current.
SMA has set a new record for transformer-based devices of this power class by achieving a maximum efficiency of up to 95.6 %.
As well as ensuring maximum effectiveness of the OptiCool active cooling system developed by SMA, an all-new, extra robust aluminum diecast housing with a dual chamber design also safely protects the electronic components from wind and weather.
