Does anyone know if I can mixed IQ7Plus and IQ7X inverters together? I have one Enphase X-IQ-AM1-240-3 M combiner box and only 4 panels with IQ7Plus inverters today. I want to move (2) 96 cell panels onto the system that are currently on a string inverter. I called a couple places about having them come look at my DIY project and the one guy freaked out when I mentioned having the two microinverters together but didn't explain. I can see that the VA is higher so I'd just assume I need to connect them on a separate branch?
