I am in the process of upgrading my solar PV system from 4.41kw to 15kw+ with batteries.
I may have some of the following available, depending on which route I go, so this is a teaser for now.
18 245w panels with 18 Enphase M215 microinverters. No issues, can be seen working via the Enphase phone app. If you buy them all I will throw in the Enphase hub (that speaks to the Enphase cloud servers). $135/panel-inverter pair, $2k for all of them including the hub. So you would just need the labor to roof mount these, and I can hook you up with my installer who is great.

A lot of stainless steel hardware - 5" double threaded mounting screws, L brackets.
