APsystems Microinverter QT2-208 Installation Manual 7
3. APsystems Microinverter QT2-208 Introduction
APsystems introduces its 2nd generation of native 3-phase quad microinverters, reaching
unprecedented power outputs of 1728VA to harness the power of today’s high-output PV
modules. The QT2-208 microinverter gives commercial installers a powerful plug-and-play
MLPE inverter that installs faster than competing solutions and is inherently compliant to
rapid shutdown requirements.
With balancing 3-phase output, 4 DC inputs and encrypted ZigBee wireless, installers and
system owners alike benefit from new QT2-208 architecture platform. The innovative design
facilitates thermal dissipation while maximizing power production. The components are
encapsulated with silicone to reduce stress on the electronics, dissipate heat, enhance
waterproof properties, and ensure maximum reliability of the system. 24/7 access to
performance data through apps or APsystems EMA web-based portal facilitate remote
diagnosis and troubleshooting.
The new QT2-208 is grid interactive through its Reactive Power Control (RPC) feature,
designed to better manage photovoltaic power spikes in the grid. At 96.5% peak efficiency
and improved reliability, the QT2-208 is a game changer for commercial solar.
