I'm surprised I did not get more of a response on this thread. Is anyone else adding onto M series microinverter systems? I'm starting to get a lot of requests to add more panels to older microinverter systems. Using the IQ combiner seems to make a lot of sense. The existing M series Envoy can just be plugged in nearby. I really like this approach but I don't want to run into a situation where I find out does not allow for this.
