Convection-cooled 4-9kW Three-Phase Solar Inverters

October 22, 2014 by Jeff Shepard

Shanghai Trannergy Power Electronics Co. Ltd. has launched a new line of three-phase inverters (TRB Series) from 4- to 9-kW. These inverters are compactly designed at only about 0.05 cubic meters and 24 kg. These inverters have a maximum efficiency of 98.1% and they use a film capacitor design to assure long operating lifetimes. The fanless cooling design is low noise, extremely silent and the enclosure is IP65 protection against water and dust. The design supports a wide range of input dc and MPPT voltages (200- to 800-Vdc) and includes an integrated dc switch.

"The 4KW to 9KW three phase TRB Series were designed for higher efficiency, wider range of input DC & MPPT voltage, smaller size, lower noise and longer lifecycle," says William Xu, Trannergy vice president, "Its maximum efficiency can reach up to 98.1 percent. Film capacitor design is made to assure longer lifecycle. Besides, the TRB series are also a fanless cooling design that are extremely silent. You can hardly hear any noise even if you are very close to it. With the release of these kind of three phase inverters, we believe that our residential and commercial customers now have a significantly better solution and option for rooftop systems."

Trannergy production and design system ensures compliance with ISO9001:2008, ISO14001:2004, and grid safety regulation of VDE-AR-N 4105, VDE0126-1-1+A1, AS4777, UTE, ENEL, RD1663, G83/2, G59/2, G59/3, IEC61727, IEC62116, MEA, PEA, etc. As of now, Trannergy's PVI/TRI/TRM Series solar inverters have been running on thousands of residential roofs and commercial PV plants in more than 20 countries.
