APsystems breaks new ground once again with the QS1, a cutting edge microinverter design accommodating up to four high-capacity PV modules up to 375W with independent MPPT. A single-phase, smart grid-compliant microinverter, the QS1 features Zigbee wireless communication over a mesh network with faster data speeds than PLC, and a wide MPPT voltage range results in a greater energy harvest for homeowners.
A true utility-interactive microinverter with Reactive Power Control (RPC) technology, the QS1 is inherently NEC 690.12 2014/2017 Rapid Shutdown compliant. The unit also builds on the successful APsystems line of multimodule microinverters, simplifying installation and reducing costs.
The unit also builds on the successful APsystems line of multi-module microinverters, offering reduced logistics costs and integrated communication and connection features.
Quad microinverter with independent MPPT
300% faster installation than conventional microinverters
Highest peak power output of 300W per channel
Ideal module match is 320W to 360W
While the QS1 voltage range works with larger modules, clipping will occur when using modules larger than 370W

Wider MPPT voltage range for greater energy harvest
Accommodates PV panels up to 375W
2.4GHz ZigBee mesh network (3X faster than PLC)
Common AC trunk cable w/ YC600; flexible, mix-and-match compatibility
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.
