We’re beginning a new product spotlight series to introduce the high-quality solar components used in our installations at Panel Upgrade Experts. Each product we select has been tested for reliability, efficiency, and compatibility with Calgary’s unique climate. Today, we’ll take a closer look at the APsystems QS1A Microinverter, a core part of many of our residential solar systems.
Why We Use APsystems
APsystems is one of the world’s leading independent microinverter manufacturers, with a decade of experience and a strong presence in the global solar market. Their microinverter technology boosts module-level power output and improves overall system efficiency by up to 20% compared to conventional string inverters.
The Role of a Microinverter
The microinverter is a crucial part of any modern solar setup. While solar panels collect sunlight and convert it into direct current (DC) electricity, most homes operate on alternating current (AC). Microinverters bridge that gap by converting DC to AC instantly, ensuring your home can safely and efficiently use the solar energy produced.
Unlike older string inverter systems, where one panel’s shading or performance issue could affect the entire array, microinverters operate independently on each panel. This maximizes output and simplifies maintenance and monitoring.
About the APsystems QS1A Microinverter
The APsystems QS1A is a high-efficiency, four-module microinverter designed for residential solar installations. Key features include:
- Up to 1200 VA peak output power for superior performance
- 300% faster installation time compared to traditional microinverters
- Four independent MPPT (Maximum Power Point Tracking) inputs for optimal energy harvesting
- 96.5% peak efficiency with advanced power conversion technology
- 10-year standard warranty with optional extensions
The QS1A’s design allows for faster installation, enhanced monitoring, and higher yield even under partial shading. It’s an ideal fit for Calgary homeowners who value both performance and cost efficiency.
