Good point, Matt. We've been required to install a revenue-grade solar production KWH meter in Oregon with every system. In 6-7 years with different inverter manus, I've never seen an inverter KWH display that wasn't, shall we say... exuberant, in relation to the revenue grade meter. Bob-O

The revenue grade meter 12 feet away says 2,564. Until I hear otherwise I am reluctant to consider Enphase reporting precise. It seems to be similar to what I would expect from a string inverter. I would be delighted to hear more anecdotes confirming your observations.
