I am installing a single string Enphase system with 12 IQ7+'s on a two-pole 20A breaker. I was planning to have an IQ Envoy for monitoring, but not an IQ Combiner.
Enphase says that I need a second two-pole 20A breaker for the IQ Envoy on my main panel. Stated reason is to avoid "line noise" and for "power line communication with panels." That sounds ridiculous to me, and I don't have the panel space for it.
Enphase suggested an alternative: I can add an IQ Combiner connected to a single breaker on my main panel. The IQ Combiner would have two breakers, one for the IQ Envoy and one for the microinverter string. The thing is, I just can't see how this is any better than simply wiring the IQ Envoy on the same circuit as the IQ7+'s. It doesn't improve communcations between the Envoy and the microinverters. Its not safer. I just don't see the benefit other than selling more Enphase stuff.
Anyone have an opinion on this? Have you tried putting IQ Envoy on the same breaker as your microinverters?
Thanks
Martin
