Marco,
 
I have a revenue grade kWh meter on my 3 Enphase 175 system that is owned by the utility (production based incentive in WA state) and the Enphase monitoring reads about 6% over the revenue meter. This has been over a one year period. I've been very pleased with the performance using either measurement.
