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.
KEY FEATURES:
- Designed for 3-phase grid connection (208V or 480V)
- Single unit connects to 4 modules up to 600W+, dual MPPT, module-level DC voltage
-
QT2 208V – 1728W output // QT2 480V – 1800W output
-
- Native 3 Phase (L1, L2, L3), Balancing 3-phase output
- Compatible with both △ and Y 3-phase grid
-
CA Rule 21 (UL 1741 SB) compliant

🇨🇦 Smart solar in the shadow of the Rockies. ☀️🏔️
The Canadian Residential Project of the Year goes to Flux Renewables for their standout 18.63kW installation near Calgary, Alberta—designed to thrive in real-world conditions, from shade to shifting terrain.
“This setup experiences plenty of shade—yet the APsystems microinverters manage it efficiently,” said Tanner Robertson, CEO of Flux Renewables. “The combination of safety, dependability, advanced tech, affordability, and simple installation made APsystems the right fit.”
Every panel operates with independent MPPT, maximizing performance and reliability—even under cloud cover and tree shadows. And when neighbors are referring neighbors? That’s a system that speaks for itself.

When one panel underperforms, should your whole system suffer?
With microinverters, the answer is no. 💡
Each panel works independently—so if one is shaded, dirty, or aging faster, it won’t drag down the others.
That’s a big difference from string inverters, where the lowest-performing panel limits the output of the entire string.
More independence = more energy. 🔋
It’s that simple.
