[RE-wrenches] Warranty Claim Based On Enphase Monitoring Data

[Bob-O Schultze]

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.

Mark,

We have nine Trina modules on our roof with Enphase.  Enphase says the
array has produced 2,680 kWh to date.  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.


Regards,

Matt
