Service department unreachable and never returns calls
The service/repairs department is unreachable and does not return calls. I have been trying to schedule service since June. The installation in 2015 was outstanding and even my roofer gave high compliments to the installation quality! However, two of the installed modules now do not send data to the optimizer - might be a connector problem or a module problem or an optimizer problem. I called in June and spoke to someone in service/repairs who said they were too backed up to schedule but confirmed the problem and said it is under warranty. They never got back to me. I then called on dozens of occasions over the next 3 months until now and not a single time did the service/repairs department answer, on any weekday, at any time during business hours. I left messages some of the time, maybe a dozen times scattered across the last 3 months. I also talked to the customer service department several times and each time, they promised to immediately let the repairs agent know and ask them to call me back. I have after all of that never once been called back to schedule the repair. As far as I can tell, repairs and warranty service is all a fiction, it doesn't actually exist. It seems it would be so easy for someone to come out to check on it and if it's a connector problem, would be fixable in just a few minutes on the spot, and if something else, then they could let me know the diagnosis and a timeline for getting the parts and being able to do the work.
