Oh no if you get used panels, buy them by the pallet, all the same, plus 1 or 2 extra.
It's a big difference. Micro inverters can easily cost 2 to 3 times that of a string inverter.

I would use micro inverters, if my panels were small enough, but let's say I had rood for 12 panels, but 10 puts me at the voltage limit for the inverter and stick those last 2 on micros, or I get a few panels on the edge of the array that get shade.

The best money in used inverters is 3 to 4kw that because those are super common and if you have to have it shipped most 4kw inverters are under the freight weight limit.
