In a major win for solar professionals and homeowners alike, APsystems has officially extended its standard warranty on the DS3 and QT2 microinverter series to an impressive 25 years for all units sold in Canada. This upgrade—effective May 1, 2025—means that installers and end users no longer need to apply or pay for extended coverage. The full 25-year protection now comes built-in as standard.
As a leading Canadian distributor of APsystems products, Circuit Solar is proud to stock these next-generation microinverters with the new long-term warranty, offering unmatched value, safety, and performance across residential and commercial solar projects.
What’s New in the 25-Year Microinverter Warranty?
Previously, APsystems microinverters shipped with a 10-year base warranty, with an option to purchase an additional 15-year extension. Now, that’s all changed. The DS3 (dual-module) and QT2 (three-phase quad-module) models now come with a 25-year manufacturer warranty standard—no additional paperwork, no additional cost.

Why This Warranty Extension Is a Game-Changer for Canadian Solar Projects
Built for Harsh Canadian Climates
From the freezing temperatures of Alberta winters to the coastal moisture of Nova Scotia, APsystems microinverters are IP67 rated, tested to withstand extreme conditions. The new 25-year warranty reflects the hardware’s real-world durability and high reliability in Canadian environments.
Boost Your Project ROI and Peace of Mind
With module-level power electronics (MLPE), installers already count on DS3 and QT2 microinverters for high-efficiency energy harvesting, even under shading and panel mismatch. Now, with a 25-year warranty, the lifetime value of your solar installation just got even better.
Fewer Callbacks, More Customer Confidence
Installers love DS3 microinverters for their ease of installation, safety, and monitoring. The longer warranty means less risk, fewer replacements, and stronger customer satisfaction—translating into more referrals and a stronger reputation.
