Currently Fronius is having a 5 plus 5 year warranty extension promotion for free until December 31st 2019. All String inverters sold by Fronius Australia enjoy the standard “Fronius Warranty Plus” for 5 years which includes parts+transportation+labour. The extra 5 years of free warranty is only the “Fronius Warranty” which only covers the labour costs.
To redeem the additional 5 years of warranty, end customers have to register online and submit their invoice. A step by step guide can be downloaded here.
