Review by John1 year ago
SMA Sunnyboy inverter failed few months before end of warranty. Despite evidence of installation date, company was reluctant at first to value warranty, leaving us with no solar power for nearly 2 months. Eventually, they reluctantly agreed to replace, apparently with a reconditioned unit, but we were not happy with this, as the new unit has no new warranty, and might possibly fail early again. The company even refused to add a warranty to cover the nearly 2 months the first unit was out of service. Until then, the unit had worked well, but this failure to cover the lost energy period is, in my view unacceptable.
The reluctance to provide a new warranty isn't, in my view, a good sign of the company's own view of the reliability of their products!
In addition, the company was very very slow to respond to all communications, regardless of whether I contacted the UK division or the German parent company. They were also reluctant to communicate directly with domestic customers, but even when my installer was involved, they were still slow, and kept wanting more and more details of the failed unit, rather than asking for all they needed at the first point of warranty claim.
I'm still trying, without success so far, to get the warranty extended, even for the lost power period until the replacement unit arrived. Even if they do that, I'll have suffered nearly 2 months of generation and had to pay £216 to an installer to replace the old unit for the one provided by SMA. I'll report back if the situation changes
