Frequently Asked Questions
What is the SMA Sunny Tripower STP X 12-50?
The SMA Sunny Tripower STP X 12-50 is a three-phase string inverter with 12.00 kW AC rated power. It converts the DC current from solar modules into grid-compliant AC current and feeds it into the grid via three phases. With transformerless topology, three MPP trackers, and a maximum efficiency of 98.2%, it is designed for commercial and larger private PV systems.
Which systems is the inverter suitable for?
With a maximum DC connection power of 18.00 kWp, 6 string inputs, and 3 independent MPP trackers, the device is suitable for systems ranging from approximately 12 to 18 kWp. The three MPP trackers allow module areas with different orientations or inclinations to be operated separately.
How many MPP trackers does the device have and what do they do?
The STP X 12-50 has 3 MPP trackers with a total of 6 string inputs. Each tracker independently regulates its area to the optimal operating point, ensuring that shaded or differently oriented sub-areas do not cause mutual yield losses. The MPP voltage range extends from 210 to 800 V.
Is the inverter suitable for outdoor installation?
Yes. With IP65 protection, an integrated DC disconnector, and an ambient temperature from -25 °C, the SMA Sunny Tripower STP X 12-50 is designed for outdoor installation — even under cool, alpine conditions. The integrated arc fault protection (AFCI) further increases safety on the DC side.
Who is SMA?
SMA Solar Technology is an established manufacturer of inverters and system technology for photovoltaic systems. The products in the Sunny Tripower series are known for their reliability and high efficiency in commercial and private use.
