DISCONTINUED: APsystems QS1 Microinverter

More power & 300% faster installation

POWER QUADRUPLED

The QS1 is a four-module, high-power microinverter for residential applications.

A new design for APsystems, the QS1 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 QS1 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.

Common AC trunk cabling with the dual-module YC600, offers flexible mix-and-match compatibility on the same circuit and with the same gateway (ECU-R or ECU-C).

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

Contact your local distributor or sales.usa@APsystems.com to bring the QS1 to your customers today.

🇨🇦 Smart solar in the shadow of the Rockies. ☀️🏔️

The Canadian Residential Project of the Year goes to Flux Renewables for their standout 18.63kW installation near Calgary, Alberta—designed to thrive in real-world conditions, from shade to shifting terrain.

“This setup experiences plenty of shade—yet the APsystems microinverters manage it efficiently,” said Tanner Robertson, CEO of Flux Renewables. “The combination of safety, dependability, advanced tech, affordability, and simple installation made APsystems the right fit.”

Every panel operates with independent MPPT, maximizing performance and reliability—even under cloud cover and tree shadows. And when neighbors are referring neighbors? That’s a system that speaks for itself.
