Frequently Asked Questions
What is the SMA Sunny Tripower STP X 15-50?
The SMA Sunny Tripower STP X 15-50 is a three-phase string inverter with 15 kW AC nominal power for grid-connected PV systems. It converts the DC current from solar modules into grid-compliant AC current and achieves a maximum efficiency of 98.2%.
Which systems is the STP X 15-50 suitable for?
With 15 kW AC power and up to 22.5 kWp connectable generator power, the device is suitable for larger residential and commercial rooftop systems. Three independent MPP trackers with a total of six string inputs allow for multiple roof surfaces with different orientations to be covered.
How many MPP trackers does the inverter have and what does shade management do?
The STP X 15-50 has three MPP trackers with an MPP voltage range of 260 to 800 V and a maximum of 24 A per tracker. The integrated shade management optimizes yield in case of partial shading by operating each string in the best possible way.
Is the inverter suitable for outdoor installation?
Yes. The housing is protected against dust and jet water according to IP65 and designed for operation from -25 °C. At 59 dB, the device also operates comparatively quietly, which allows installation near residential areas.
