That jives with their technical paper on the subject, but still doesn't explain why (neither does the paper).
I'm also a little suspicious about the average temp thing. I mean, where I live the historical average year round is 73. But, it's in the 50's in January & easily 110 in July. Why would the average matter? Seems an overdriven inverter would not be happy in the summer here?
Pretty confusing, but I've heard the overrating thing from 3 different installers now.
