The cost-efficient, flexible, and safe microinverter solution for residential and small-to-medium commercial rooftops — built for the latest generation of high-power PV modules.

Driven by innovation in solar energy transformation, the APsystems QS2 single-phase quad microinverter is purpose-built for distributed solar applications. With 4 MPPTs, it delivers greater power generation capacity reaching 2,200 VA AC output and combines key advantages—safety, reliability, high efficiency, flexibility, and intelligent management. The components are encapsulated with silicone to reduce stress on the electronics, facilitates thermal dissipation, enhance waterproof properties, and ensure maximum reliability of the system via rigorous testing methods including accelerated life testing. A 24/7 energy access through apps or web-based portal facilitate remote diagnosis and maintenance. The new QS2 is interactive with power grids through a feature referred to as RPC (Reactive Power Control) to better manage photovoltaic power spikes in the grid.
