APsystems Extends Standard Warranty to 25 Years for DS3 and QT2 Microinverters, Underscoring Long-Term Reliability

This major upgrade—expanding from the previous 10-year standard warranty with an optional 15-year extension—underscores APsystems’ commitment to long-term product reliability and customer satisfaction.

APsystems, a global leader in solar microinverter technology, is proud to announce that its DS3 and QT2 series microinverters now come with a 25-year standard warranty in the U.S. This major upgrade—expanding from the previous 10-year standard warranty with an optional 15-year extension—underscores APsystems' commitment to long-term product reliability and customer satisfaction.


The new 25-year standard warranty officially went into effect on February 15, 2025, covering all DS3 and QT2 microinverters moving forward. With this enhancement, APsystems eliminates the need for customers to take additional steps to secure extended coverage, ensuring that all units are backed by 25 years of comprehensive protection from the outset.

"Our products are designed to last, and now our warranty fully reflects that," said Doug Hewitt, U.S. Country Director at APsystems. "By extending our standard warranty to 25 years, we're not only demonstrating the durability of our microinverter technology but also making it more convenient for our customers—eliminating extra paperwork and providing the peace of mind that comes with long-term coverage."

The new warranty coverage applies to all DS3 and QT2 microinverters sold in the U.S. and takes effect from the earlier of:

Vecoplan - Planning and implementation of complete processing plants in refuse derived fuel production

In order to reduce the costs involved in the energy-intensive production of cement, many manufacturers are turning to refuse-derived fuels (RDF), considerably reducing the proportion of expensive primary fuels they would normally use. Solid fuels are being increasingly used - these might be used tyres, waste wood or mixtures of plastics, paper, composite materials and textiles. Vecoplan provides operators of cement plants with proven and robust components for conveying the material and separating iron and impurities, efficient receiving stations, storage systems and, of course, efficient shredders for an output in various qualities.
