Fronius has announced a promotion extending its manufacturer’s warranty by ten years. Until December 31 this year, customers who extend their standard inverter warranty from five to 10 years will see their guarantee increased to 20 years free of charge.

The extended warranty applies to all new installations from July 1 this year and is valid for the Fronius IG, Fronius IG Plus, Fronius IG TL and Fronius CL series.

The promotion excludes inverters that conform to UL 1741 requirements, carry a CSA mark or are intended for the US market.

Fronius is supporting Solar Power UK 2011, which is running from October 26 – 28.
