PV inverter still not working, who can I complain to?

scotcat

Hello, I am looking for some advice.  We had solar panels fitted March 2019. The system has stopped working 3 times., I have lost about 2 months of generation last summer and it's now not been working since April. We have a solaredge Inverter which they diagnosed as being faulty and even sent as new one in June which we had to have fitted at our expense. Despite a second electrcian callout it's still not working. I'm so frustrated with solaredge, they can take up to two weeks to reply to an email (this was pre lockdown!), I can't get them on on the phone and they left the electrician waiting 35min on the dedicated installer helpline.  Where can I complain about this service and product? 
Many thanks for any suggestions, Cat

Did you factor in to your original financial calculations the cost of replacing inverters. How has your original forecast been affected.
Out of interest, what have your repair and maintenance costs been to date..._

There is no official complaints line to go to.

Your rights are against whoever sold you the inverter. They should be fixing it at their expense, assuming they haven't gone bust like most installers do.

But even if they have gone bust, most (or perhaps only many) installers were offering insurance-backed warrantees.  Surely such warrantees outlive the fated installer-businesses?
