APsystems Launches the QS2 Microinverter: Maximum Power, Reliability, and Flexibility for Modern Solar Rooftops

Designed to meet the growing demands of today’s high-power PV modules, the QS2 sets a new benchmark in performance, safety, and installation efficiency.

The QS2 microinverter is optimized for modern high-output panels, supports four modules per unit with independent MPPTs, and provides reliable performance with proven safety features. It is especially attractive to installers who value scalability, easy installation, and long-term reliability.

The QS2 is a quad microinverter that connects up to four modules, each with independent MPPT and monitoring, delivering a maximum continuous output power of 2200 VA. With 99.5% MPPT efficiency and 96% peak efficiency, the QS2 ensures maximum energy harvest, making it ideal for both residential and small-to-medium commercial rooftop systems.

“Installers are looking for solutions that combine power, flexibility, and safety,” said Maxime Boiron, Marketing Director at APsystems. “The QS2 delivers all of this in a compact, reliable design that is easy to install and perfectly aligned with the latest high-power PV technologies.”

Key features include:

  • High productivity: Optimized for next-generation PV modules, delivering superior efficiency.
  • Smart design: Four independent MPPT channels, encrypted ZigBee communication, and compatibility with APsystems’ DS3 series for maximum flexibility.
  • Proven safety: Low 60V DC input, rapid shutdown compliance, and galvanic isolation for ultimate protection.
  • High reliability: IP67-rated enclosure, silicone-encapsulation for durability, and rigorous lifetime testing

Smarter Connectivity with Upgraded ZigBee on QS2
The new QS2 microinverter features an enhanced ZigBee communication module, designed for greater speed, stability, and efficiency.
With 50% lower power consumption, 50% faster chip frequency, and 10× memory capacity, the upgraded ZigBee ensures robust performance. The improved MESH network enhances real-time data flow and system reliability, even in large or complex rooftop setups. AES-128 encryption and anti-interference design further secure your energy data, making QS2 smarter from the inside out. The QS2 is backed by APsystems’ standard 12-year warranty, extendable to 25 years, ensuring long-term peace of mind for both installers and system owners. With the QS2, installers can reduce balance-of-system costs, streamline installations, and deliver future-proof solar solutions that adapt to the evolving PV landscape.

The QS2 microinverter is now orderable and available at our distributors.
