To that end, Fronius USA is bumping up the warranty duration for all new Fronius solar inverter installations – from 10 years to 12 years of warranty – at no additional cost.

Yes, effective on March 1, 2024, newly installed Fronius inverters in the United States of America are eligible for the two additional years of material warranty. You’ll just need to go online and register for it.

We want to express our gratitude by offering this extended warranty for free and giving customers additional peace of mind.”
