Transphorm GaN powers DAH Solar PV systems

New SolarUnit product line integrates 150 mΩ and 70 mΩ GaN FETs

GaN chip specialist Transphorm has announced that its GaN FETs power DAH Solar’s new highly integrated microinverter PV systems, known as the SolarUnit product line.

DAH Solar credits Transphorm’s GaN FETs with enabling it to produce smaller, lighter, and more reliable solar panel systems that also offer higher overall power generation with lower energy consumption.

DAH Solar uses Transphorm’s 150 mΩ and 70 mΩ GaN FETs within the SolarUnit product line (both DC-to-DC and DC-to-AC power stages). The SolarUnits are available in three models with power outputs of 800 W, 920 W, or 1500 W and peak efficiencies of 97.16 percent, 97.2 percent, and 97.55 percent respectively.

Yong Gu, GM, DAH Solar said: “We view Transphorm as an authority in the field of GaN production and found their advanced GaN FETs to be the optimal devices for our new SolarUnit line. The devices are easy to design in and offer performance advantages that enable us to continue building on our legacy.”
