Just FYI, my tiny direct grid-tie system (with a Sunny Boy inverter) keeps track of delivered kWh, but also by law I have to have its output go via a separate 'total generation' meter.

Both nominally record output with a precision of 0.1kWh or better.

We're at around the 700 mark since install and the two readings differ from one another by several percent IIRC. And indeed, the 'total generation' meter by whose reading I will be paid is the more generous of the two!

It's maybe a somewhat less exact science than we'd like.
