Applications

The SMA Sunny Tripower STP20000TL-US series is a commercial-grade three-phase string inverter used in ground-mount, rooftop, and carport solar installations where three-phase grid connection is available. With a 20 kW output rating, it is well suited to commercial buildings, schools, warehouses, and small utility installations that pair multiple string inverters in a larger array. The Sunny Tripower line is known for its transformerless topology, which reduces weight and improves efficiency compared to transformer-based inverters of the same era. The STP20000TL-US-10 includes integrated Ethernet communication, allowing monitoring and data logging via SMA's Sunny Portal or compatible SCADA systems. This model was produced for the North American grid-tie market and targets installations requiring three-phase AC output to match commercial utility service.
