Details

The 2nd generation APsystems QT2 microinverter delivers unprecedented power outputs of up to 2000VA, designed to support today’s higher-power PV modules. Featuring balanced 3-phase output, four independent DC inputs, and encrypted Zigbee communication, the QT2 is built on an entirely new architecture that maximizes energy production while ensuring seamless grid integration.

Encapsulated with silicone for enhanced thermal dissipation, waterproofing, and stress reduction, the QT2 is rigorously tested for durability, including accelerated life testing. With 97% peak efficiency and 20% fewer components than its predecessor, the QT2 offers superior reliability and performance.

Equipped with Reactive Power Control (RPC) for grid stability, the QT2 actively manages power fluctuations to optimize solar output. Additionally, 24/7 real-time monitoring via app or web portal enables remote diagnosis and maintenance, making the QT2 an ideal choice for high-performance commercial and industrial solar installations.
