PV Transformerless Inverter

As one of Conergy’s global strategic partners, SMA was the first solar inverter companies in the world to receive certification from UL for transformerless PV inverters. The transformerless design of the PV inverters reduces weight, increases the speed of payback and provides optimum value for any decentralized, commercial PV system. The new Sunny Boy TL-US series features SMA’s innovative H5 topology, resulting in superior efficiencies of up to 98 percent and unmatched solar yields. This transformerless series is the ideal choice for mid-size and large plants from 24 kWp up to the megawatt range.
