Hi ralnavman, did you go ahead with the upgrade?
I’ve been contacted by what I think must be the same company and they similarly are suggesting that any problems with the inverter or optimisers would be covered over the next 20 years.
Has anyone had any other experience with getting some of this ‘warranted’ equipment replaced? Do you have to go out and find (and pay for?) someone else to do the actual equipment change if/when something fails?
