APsystems Launches QS1 Four-Module 1200W AC Microinverter


ANAHEIM – September 24th, 2018 – APsystems unveils the QS1, a four-module, single phase microinverter for residential applications at the Solar Power International trade show in Anaheim. A new design for APsystems, the QS1 offers 75% faster installation time, while offering the highest peak output power and up to 3X faster data transmission speed than PLC. A wider MPPT voltage range will result in a greater energy harvest for homeowners.

The first of its kind, the QS1 is designed to accommodate today’s high output PV panels up to 375W, offering 300W AC output per channel, the highest among microinverters. The unit also significantly reduces installation time and costs, taking the place of four conventional microinverters per each QS1 installed while still providing four independent MPPT.

The QS1 utilizes a common AC trunk cabling with the dual-module YC600, offering flexible mix-and-match compatibility on the same circuit to enhance site design capability and maximize circuit capacity. Both microinverters also utilize the same gateways; installers can choose from the ECU-R, for single or multi-residential installations, or the ECU-C, for applications requiring consumption monitoring and advanced contact/relay features.

“Compatibility with the existing YC600 microinverter system gives the QS1 an unprecedented advantage,” said APsystems Chief Technology Officer Dr. Yuhao Luo. “Mixing dual and quad microinverters in the same system adds design flexibility while offering a strong inventory and installation labor advantage over conventional microinverters.”

Today’s solar systems require a more robust communication architecture to manage significantly more data points and in-field software updates. A 2.4GHz wireless Zigbee mesh network offers enhanced data transmissions speed, up to three times faster than conventional powerline communication (PLC).

The QS1 builds on the successful APsystems line of multi-module microinverters, offering reduced logistics costs, integrated communication and connection features, and a wider MPPT voltage range for greater energy harvest during low light conditions.

New YC600 brings even more power to Magnolia installation

The powerful new YC600 microinverter from APsystems is the forward-thinking choice in all solar markets. One of our Seattle-area installers Puget Sound Solar chose the YC600 for a recent residential installation in the Magnolia neighborhood, where homeowners will benefit from the 300VA peak output to take maximum advantage of Washington state’s progressive net metering program. The 7.7kW system called for 22 modules arrayed over four distinct roof slopes on the multi-story home, using APsystems microinverters for design flexibility. Inherently smart-grid compliant with Reactive Power Control technology, the YC600 is designed and built for utility-interactive requirements today and into the future. Learn more about the revolutionary YC600 microinverter here.

APsystems EMA mobile app now features module-level monitoring

APsystems now offers the same, widely popular module-level monitoring features from its online EMA portal in its convenient mobile app. The EMA app displays solar array power production by day and month, as well as current panel-by-panel performance.

The app also features a date selection tool which displays module-level performance on a specific date and time for even more in-depth monitoring.

In module view, users can select a specific module to view details, view a time-lapse or scrub through the timeline with their finger, and pinch the screen to zoom in or out.

These new EMA app features offer solar system owners even more ways to monitor their system performance, troubleshoot issues and even showcase their energy independence to their friends! Find out more about APsystems mobile apps here.

APsystems microinverters touted in Solar Builder magazine

APsystems microinverters get a shout-out in the January edition of Solar Builder magazine, on newsstands and online now.

Tim Bailey, founder of Blue Frog Solar, touts microinverters as a great way for smaller installers to lower soft costs by simplifying residential system design—a big advantage over complex string inverter systems.

“Microinverters are flexible, and installers can design in the field by adding modules as they see fit,” Bailey says.
