I really like micro inverters one reason is one thing cannot take the whole array off line. Sure you have a inverter warranty but it does not cover lost power being made we make from $200-$100 a month if you are down for a few month that adds up fast. (just under $2,000 a year)
If a microinverter fails I have a spare on hand I replace it send bad one off for warranty no big deal. (I have had not failures yet knock on wood)
Another reason it you can check each panel/microinverter at a glance and if one is having issue it is very simple to see. It is very easy for a home owner trouble shoot the issue. You don’t have to wonder if it is working or call someone in to look at in for $100 and hour plus travel.
This view is priceless for trouble shooting.
You can also graph a single Microinverter.
