The Power of Quad Microinverters for Commercial Rooftops
/in General News, Press Coverage/by APsystems TeamAs part of Solar Power World’s 2023 Trends in Solar series, an article was recently published entitled, “Mightier microinverters can power 4 solar panels,” that highlights APsystems as the forerunner in making a four-in-one (quad) microinverter as early as 2014. In addition, the article features Jason Higginson, senior marketing director of APsystems, providing information on why microinverters are now ideal for commercial solar applications due to the quad design. In particular, quad microinverters reduce cost, speed up installation and produce more energy over the life of the system.

QT2 Now Shipping!
/in General News/by APsystems TeamThe new QT2, a 3-Phase microinverter for C&I applications, connects to up to 4 PV modules, is rapid shutdown and UL 1741 SA (CA Rule 21) compliant and comes in 1728W (208V) and 1800W (480V) output models.
Why microinverters in commercial solar? As featured in the recent Solar Builder article “Making the case for microinverters in C&I solar,” QT2 microinverters offer built-in rapid shutdown, pairing with higher capacity PV modules, improved performance over string inverters under a variety of conditions, fewer potential points of failure, plug-and-play three-phase wiring, and are more cost-effective than ever.
A new cooling topology allows the QT2 to reach unprecedented levels of high efficiency power conversion, while embedded 2.4GHz ZigBee wireless communication provides high speed data transfer of production data. Solar installers can now offer their C&I customers all the benefits of MLPE in an easy-to-install, plug-and-play, native 3-Phase microinverter package.

QT2 Featured in Solar Builder Article
/in General News, Press Coverage/by APsystems TeamIn its recent article entitled “Making the case for microinverters in C&I solar,” Solar Builder mentioned the new QT2 microinverter, APsystems’ commercial 3-phase product. The article describes the changing dynamics of using microinverters in commercial solar projects and how many of the past hang-ups and limitations no longer exist. In fact, microinverters now make more sense than string inverters + rapid shutdown systems in many applications.
