We purchased a solar power system with a 2kw inverter (made in China) 5 years ago with 25 years warranty for the solar panels' performance and 5 years warranty for the inverter. Just two months over the 5 years period, the inverter broke (few days ago) and we want to replace it with another brand new inverter of European manufacture which the original supplier doesn't stock. The questions are: - We still have 20 years warranty for the solar panels from the original supplier, if we buy an inverter and have it installed from another company; will the panels warranty still be effective? - A representative from another company told us that we would have to go back to the original supplier in order to have the panels warranty otherwise, the warranty would be void; is it correct under Australian Consumer Law? Thanks in advance for your answer!
