Aw, one more Enphase / SolarEdge response. The "high voltage" DC is 350-380 volts and with the rapid shutdown capability now shipping standard with SE inverters, they go to 1 volt per optimizer when the AC grid is not present. By the way, that 1 volt per optimizer is a great way during installation to confirm proper connections - string of 10 means an installer should see 10 volts.
No bottle neck issue. The optimizer in essence is doing the MPPT function at each module. So if shading, the Opt "finds" best voltage to maximize power output. No string degradation. Mixing modules is not a factor whatsoever. Best part is that since I only MPPT on roof and don't invert, I have a string inverter on the side of the house that only does one function - invert! Why try to invert DC to AC on a HOT roof when I could do it with a much higher efficiency box that is more robust on the side of the house or in a garage? I've gone away from microinverters entirely - too many nuisance faults. And each nuisance fault is a phone call to customer support that is handling more than they can handle by a ratio of...number of MLPE to string inverters essentially.

At some point you are still dealing with high voltage DC, so safety is far better with off the roof 240V AC; you still have the bottleneck if one module is shaded or corroded; and you still have the difficulty of replacing a legacy module to build a compatible string. Again I am not unhappy about Enphase hardware. I just think they've grown too fast to keep their support as well organized as the rest of the company.

With SolarEdge there is no trunk cable, which definitely cuts down on wire management, especially using SnapNRack mounting. Everything is MC4, so PV wire to a transition box, to the inverter input(s) make it pretty simple. We almost always mount our inverters outside, even when they are string inverters, and typically on the north side of the home/business. My guys didn't like the changeover on the first SolarEdge job, but it only took one to bring them around and they are now converts.
