APsystems QS2 Microinverters

APsystems’ Most Powerful Three-Phase Quad Microinverter

The APsystems QS2 Series redefines solar performance by combining up to 2500 VA of output power with four independent MPPTs, allowing each module to operate individually and deliver maximum energy production under any installation condition.

Engineered for today’s high-power PV modules, the QS2 provides a flexible, efficient, and scalable solution for residential and commercial projects seeking to maximize energy yield and return on investment. Its next-generation architecture optimizes solar production even in installations affected by partial shading, multiple roof orientations, or varying irradiance conditions across modules.

By connecting up to four PV modules to a single microinverter, the QS2 simplifies system design, reduces installation costs, and enhances overall project efficiency. Integrated encrypted ZigBee communication and full compatibility with APsystems ECU gateways and the EMA monitoring platform provide intelligent module-level monitoring, remote diagnostics, and complete real-time system visibility.

Built to APsystems’ highest standards of quality and reliability, the QS2 incorporates advanced safety features, delivers peak efficiency of up to 96%, and utilizes an optimized architecture designed to ensure outstanding long-term performance.

With greater power, enhanced flexibility, and intelligent monitoring for every panel, the APsystems QS2 Series is the ideal solution for taking residential and commercial solar installations to the next level.
