Are they telling you the problem is the connection in the meter base? We get

Wrenches,
We have recently had a string of Solectria 3.8 failures. The commonality
to the failures seems to be a failed internal relay on the top part of the
inverter and we (and one customer) have witnessed brief arcing occur as
the inverter attempts to start up. In every instance we have seen

I would recommend you consider using a tool like PVsyst or Helioscope to
model DC:AC ratios. A quick modeling of roughly 200 kW on three Solectria
50 kW inverters shows about 1.3% clipping here.
It then comes down to analysis of your costs for additional modules, dc
wiring, and inverters.
I am shocked anyone would refer to SMA's tech support (at least in the
past year) as good. At least 50% of the time that I have to call SMA I
end up on hold for 45 minutes before the automated system just hangs up on

To answer your first question, you can wait 45 minutes on hold before SMA

This does not exactly answer your question but SMA Sunny Design indicates
