I have them installed. Super happy with them. There is really good training on the system available at
https://www.solaredge.com/en/installers/learning-center.
A key differentiator between Solar Edge and Enphase is this:
Solar Edge has optimizers at each panel and sends DC to a single inverter which connects to the building and its services at or near the first means of disconnect.
Enphase has mini inverters at each panel and sends DC to the panel.
There are arguments for each approach. For me it boils down to:
1) Want to add another panel to Enphase... really easy... just add it.
2) For SolarEdge, there is only one DC to AC conversion... so if you're going to batteries, cars, etc... you aren't inverting/converting multiple times.
