4) Do not worry about overloading your grid Inverter.
I use mostly micro inverters and do not worry about overloading them. I do have one string 5kw inverter that is fed by 8kw worth of panels. It does indeed "peg out" at 5kw.
I do overload my transformer. I have 30+kw of PV feeding into a 15kva transformer. Static voltage is 245-248vac. As my production rises above 10kw, my voltage rises to 260 and a bit beyond. Above about 258v inverters start shutting down; their energy lost. I rarely see more than about 16kw produced. I have requested that my utility upgrade the transformer to 37.5 kva. Also requested, a lower static voltage. Producing more total energy with my current transformer is my primary interest in east-west pointing.
