APsystems QT2 2000 VA 3-phase quad microinverter

The APsystems QT2 is the most powerful quad microinverter for three-phase grid connections, delivering up to 2000 VA of AC output power. Designed for both residential and commercial PV systems, it features four low-voltage DC input channels, 2 MPPTs, and encrypted Zigbee communication for reliable monitoring and control.

The QT2 incorporates an integrated VDE relay and RPC (Reactive Power Control) to interact with the power grid and manage voltage fluctuations. With a peak efficiency of 97%, natural convection cooling (no fans), and silicone encapsulation for enhanced durability, the microinverter operates reliably from -40 °C to +65 °C. The IP67-rated housing provides full protection against dust and water ingress.

Suitable for panels rated 315 Wp–670 Wp+, the QT2 accepts up to 20 A of input current per channel and provides balanced three-phase AC output with an adjustable power factor and frequency range. Real-time monitoring is available via the EMA (Energy Management Analysis) system, accessible through a mobile app and web portal for remote diagnostics and maintenance.
