APsystems is introducing its new three-phase microinverter for C&I applications at this year’s RE+ show. The new QT2 connects to up to four PV modules, is rapid shutdown and UL 1741 SA (CA Rule 21) compliant and comes in 1,728 W (208 V) and 1,800 W (480 V) output models, maximizing energy production while providing all the benefits of modular-level power systems.

A new cooling topology gives the QT2 high-efficiency power conversion, while embedded 2.4-GHz ZigBee wireless communication provides high-speed data transfer of production data. Solar installers can now offer their C&I customers all the benefits of MLPE in an easy-to-install, plug-and-play, native three-phase microinverter package.

“The QT2 series represents a significant breakthrough in solar panel current and power, power density, conversion capability,” said APsystems CTO Yuhao Luo. “This powerful capability combined with intelligent firmware, built-in rapid shutdown compliance and fast installation makes this a truly unique product in the marketplace.”

QT2 Series microinverters offer the following features and benefits:

• Native 3-Phase, 4-module microinverter
• Designed to harness today’s high-capacity PV modules 400W to 600W+
• 99.5% MPPT efficiency
• Reactive Power Control (RPC) and UL 1741 SA (CA Rule 21) compliance, meeting interconnection requirements
• Inherently compliant with NEC 690.12 Rapid Shutdown requirements
• Supports a high input current, up to 20A
• More intelligent, streamlined architecture
• Future-proof with remote upgradeability
• 20% fewer components for increased reliability
• Improved enclosure design and topology for better cooling at high temperatures
• Encrypted Zigbee wireless for faster communication speed and enhanced system security

The QT2 series continues to build on the successful APsystems line of multi-module microinverters, offering reduced logistics costs, faster installation, improved communication and connection features, and a wide MPPT voltage range for greater energy harvest during low light conditions.

QT2 series microinverters will be on display at the APsystems Booth #2838 at RE+ International.
