Maximize Your 3-Phase Power with QT2 Quad
APsystems introduces its 2nd generation of native 3-phase quad microinverters, reaching unprecedented power outputs of 1728VA (for 208V) and 1800VA (for 480V) to harness the power of today’s high-output PV modules. The QT2 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 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 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 is a game changer for commercial solar.
Special Report: The Case for Microinverters in C&I Solar
Technology is revolutionizing the design of commercial and industrial (C&I) rooftop solar systems, and one innovation leading the way is microinverters. With panels reaching unprecedented capacities of 600 W and beyond, and the emergence of UL 3741 compliant systems that provide more options for meeting NEC 690.12, microinverters are set to simplify C&I solar, just as they have transformed the residential solar sector. In this special report, Solar Builder magazine explores the advancements and benefits of microinverters tailored for C&I applications with APsystems.
