Frequently Asked Questions
What is the SMA Sunny Tripower STP X 25-50?
The SMA Sunny Tripower STP X 25-50 is a transformerless, three-phase string inverter with 25 kW AC rated power. It converts DC current from solar panels into grid-compliant AC current and is suitable for larger private and commercial PV systems.
Which systems is the STP X 25-50 suitable for?
With 3 MPP trackers, 6 string inputs, and up to 37.5 kWp DC input power, the inverter is suitable for medium to large rooftop systems. The three independent trackers allow the connection of differently oriented or inclined module fields.
How many MPP trackers does the device have and what are the benefits?
The STP X 25-50 has 3 MPP trackers with an MPP voltage range of 430 to 800 V. Each tracker regulates its module string separately to the optimal operating point, allowing for yield-efficient integration of partial shading or different roof areas.
Is the inverter suitable for outdoor use?
Yes. With IP65 enclosure protection class, an operating temperature range from -25 °C, and integrated arc fault detection switch (AFCI) as well as a DC disconnector, the device is designed for wall and outdoor mounting and can be used even under alpine conditions.
