Micro-inverter APsystems QS2, 2200W/2200VA, single phase - 12 years warranty

The APsystems QS2 micro-inverter is a high-performance photovoltaic solution designed to maximize energy production in residential and small commercial (C&I) installations. Developed for professional installers, it offers enhanced system flexibility while optimizing the output of each individual solar panel. With an output power of 2200W / 2200VA in single-phase configuration, the QS2 is capable of handling multiple high-power photovoltaic modules, making it ideal for modern high-efficiency panels. Its multi-MPPT architecture allows independent optimization of each input, reducing the impact of partial shading, different orientations or module mismatch. This results in a significant increase in overall system efficiency and energy yield. Designed for easy and secure installation, the APsystems QS2 simplifies AC cabling and eliminates many of the constraints associated with traditional string inverters. Its robust design ensures reliable operation in harsh outdoor conditions, with strong resistance to environmental stress such as temperature variations and humidity. The micro-inverter integrates seamlessly with the APsystems ecosystem, including advanced monitoring solutions that provide module-level performance tracking. For installers, this solution reduces installation time and minimizes complexity, especially in projects with challenging layouts. It also enhances system safety by operating at lower DC voltages, reducing electrical risks. In residential applications, the QS2 is particularly well suited for self-consumption systems with complex roof layouts or shading constraints. It is also an excellent choice for small commercial projects or system extensions. The APsystems QS2 micro-inverter is therefore a strategic solution for improving performance, safety and flexibility in modern photovoltaic installations.
