APSystems microinverter technology individually monitors and maximizes power generation for each module in the array, boosting system efficiency by up to 20 percent. Each APsystems microinverter handles multiple PV modules, lowering logistics, installation and balance-of-system costs.

All APsystems microinverters are engineered to inherently comply with 2014/2017 NEC 690.12 requirements for Rapid Shutdown out of the box, ensuring safety of system installers and emergency responders. Click here to see the NEC 2014/2017 code compliance document and the APsystems Rapid Shutdown flier for more details.

A new design for APsystems, the QS1A offers 300% faster installation time, while offering the highest peak output power and up to 3X faster transmission speed than conventional microinverters. A wider MPPT voltage range will result in a greater energy harvest for homeowners. The first of its kind, the QS1A is designed to accommodate today’s high output PV panels, offer enhanced capability and significantly reduce installation time and costs while providing an unprecedented level of power with four independent MPPT per channel.

The unit also builds on the successful APsystems line of multi-module micro inverter, offering reduced logistics costs and integrated communication and connection features.
