Inverter repair job

OK now the numbers are looking a little better. We had an inverter die on us in June. This put me 1 panel down. That's a 2% reduction in output, so we would have made projection if it was working in July.

Now fixing it wasn't easy. I sent the installer a note. System has not been running for a year yet. He responded by telling me that he had been having trouble dealing with Enphase, so I was on my own. Not exactly the response I was hoping for. Anyway I phoned the Enphase help line. Waited for an hour and a half to talk to a live body. He was disappointed that I had already swapped the inverter with another location said that I should not do this on my own. Don't understand why not. Not a fun job but it can be done.

 He said he would put a request for a RMA number in. Then I waited a week. No info from them at all. I then sent an e-mail to every address I could find for them. 2 days later I finally got a response that a ticket number had been generated. That's all they said. Didn't know what that meant. But 2 days later I received a new inverter in the mail. Complete with a return postage for purolator. Put it up that night. Then I took my sheet with the Mac address numbers and updated it with the new locations of the 2 inverters. The one I originally swapped and the location of the new one. Sent the the new information to the Enphase web site. 2 days later and web page is back up and running fine. Whole thing took about 5 weeks. 

While I was up on the roof. I decided to get ready for next winter. Had a problem with the snow not coming off by itself. One main reason is that there is a gap between the rows of panels.

When the snow slides off of the top panel it gets stuck on the gap to the next one. Then it freezes on at night and you won't get it off until a warm day. And then the panel won't produce. It's dark after 5:00 here so I really didn't want to remove the snow until the weekend. When I could see what I am doing. This problem really reduces the system output. So I moved the panels together. This should help. Next I stated cutting off the bolts. They are all sticking up.

I bought snow rake last year. It is made of plastic so it won't scratch the panels. But it gets caught on every stud that is sticking up. So I took each one off and cut it to size.

This should work a lot better. We will let you know. 

So September is coming. When it is complete I will have been running for 1 year. I will give you a report on what the return on investment is at that time. So see you later.
