Frequently asked questions
What is the SMA Sunny Tripower STP X 20-50?
The SMA Sunny Tripower STP X 20-50 is a three-phase, transformerless string inverter with 20 kW AC rated power. It converts the DC current from solar modules into grid-compliant AC current and is suitable for larger private and commercial PV systems.
Which systems is the inverter suitable for?
With a maximum DC connection power of 30 kWp, 3 MPP trackers and 6 string inputs, the STP X 20-50 can be flexibly designed. Differently oriented or tilted roof areas can be distributed separately to the three MPP trackers.
How many MPP trackers does the device have and what are the benefits?
The device has 3 independent MPP trackers. Each tracker independently regulates the optimal operating point of its module string, so that east-west or shaded partial areas each deliver their maximum yield. The integrated shade management additionally supports this.
How does the STP X 20-50 ensure safety?
The inverter has an integrated DC disconnect switch and an AFCI (Arc Fault Circuit Interrupter) arc fault protection, which detects and shuts down dangerous arcs on the DC side. The IP65 protection class allows installation indoors and outdoors.
Who is SMA?
