[RE-wrenches] Module - microinverter compatibility question

[Jason Szumlanski]

The VOC will start the microinverter, but I would pair a 365W module with
the IQ7+. It depends on where you are and how.much clipping there might be
based on temp, orientation, etc. But, the IQ7+ is now in short supply, so
you might want to look at the IQ8+.

I have never had an issue with a module voltage close to the microinverter
specified startup voltage.
