APsystems QT2 3-phase 4-in-1 microinverter
The QT2 microinverter is delivered with all necessary components: bus cable for one QT2, QT AC bus connection cap, AC connector (5C, 40A, male and female), and QT AC bus end cap. The ECU-R product is optional and can be selected as needed.
The new QT2 utilizes Reactive Power Control (RPC) to better manage photovoltaic power peaks on the grid, achieving an impressive peak efficiency of 97 %. With 20 % fewer components than the previous generation, it sets new standards for 3-phase installations on residential and commercial PV rooftops.
Important note: This product is designed exclusively for three-phase operation and is not compatible with Schuko sockets. Installation may only be performed by qualified personnel. In the event of an incorrect purchase, the purchaser is responsible for the return shipping costs.

Maximum performance with QT2 Quad
APsystems introduces the second generation of native 3-phase quad microinverters, featuring unprecedented power ratings of 1728VA (for 208V) and 1800VA (for 480V). These microinverters are specifically designed to maximize the performance of today's high-performance solar panels.
Innovative architecture for optimal performance
Featuring a balanced 3-phase output, 4 DC inputs, and encrypted ZigBee wireless, the new QT2 architecture offers numerous benefits to both installers and system owners. The innovative design promotes heat dissipation and maximizes energy production, resulting in improved overall performance.

Real-time monitoring and network interactivity
With 24/7 access to performance data via apps or the web-based APsystems EMA portal, users can perform remote monitoring, rapid diagnostics, and troubleshooting. Additionally, the QT2 is grid-interactive and features Reactive Power Control (RPC), which is designed to better manage photovoltaic power peaks on the grid and achieve an efficiency of 96.5%.
