SMA STP50-US-41 Sunny Tripower CORE1 US-50 50kW 3-Phase Solar Commercial Inverter.

The Sunny Tripower CORE1 is the world’s first standing PV inverter for commercial rooftops, carports, ground-mount and repowering legacy solar projects.Now with expanded features and new power classes, the CORE1 is the most versatile, cost-effective commercial solution available. From distribution to construction to operation the Sunny Tripower CORE1 enables logistical, material, labor and service cost reductions. Integrated Sunspec PLC for rapid shutdown and enhanced DC AFCI arc-fault protection ensure compliance to the latest safety codes and standards. With Sunny Tripower CORE1 and SMA's ennexOS cross sector energy management platform, system integrators can deliver comprehensive commercial energy solutions for increased ROI.


  • SunSpec compatible inverter technology in conjunction with the TSA-R-F, which gives integrators a cost-effective way to achieve compliance with NEC 2017 module-level shutdown
  • Advanced AFCI compliant to new Standard UL 1699B Ed. 1 for arc fault.
  • SMA Smart Connected proactive service strategy which can cut truck rolls in half.
  • 480V / 277V WYE Nominal AC Voltage
