QS1A Quad Module Micro Inverter by APSystems

The APsystems microinverter is smarter.

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  ¹to see the NEC 2014/2017 code compliance document and the APsystems Rapid Shutdown flier for more details.
