APsystems QT2 3-Phase Quad Microinverter
APsystems’ second generation of native 3-phase quad microinverters delivers unprecedented power output of up to 1,728 VA for 208V systems and 1,800 VA for 480V systems, helping installers take full advantage of today’s high-output PV modules.
The QT2 gives commercial installers a powerful, plug-and-play module-level power electronics (MLPE) solution that installs quickly and is inherently compliant with rapid shutdown requirements.
With balanced 3-phase output, four DC inputs, and encrypted ZigBee wireless communication, both installers and system owners benefit from the advanced QT2 architecture. Its innovative design promotes effective thermal dissipation while maximizing power production.
Internal components are encapsulated with silicone to reduce stress on the electronics, dissipate heat, improve waterproofing, and enhance overall system reliability.
System performance data is available 24/7 through APsystems apps or the APsystems EMA web-based portal, allowing for convenient remote monitoring, diagnostics, and troubleshooting.
