Microinverters are a common component in residential solar projects that are built to handle the wattage of smaller-scale PV arrays. But like solar modules, microinverters are increasing in capacity and can handle larger electrical loads. For example, inverter manufacturer APsystems’ new QT2 microinverter can invert energy from four solar panels at a time, unlike previous models that were installed on single modules. Jason Higginson, head of marketing for APsystems USA, is here to discuss this new breakthrough and the subsequent trend of microinverters entering the commercial and industrial solar market.
