<DIV><BR></DIV><FONT face=sans-serif size=2>Hi:</FONT> <BR><BR><FONT
face=sans-serif size=2>The difference is in the accuracy of revenue grade
versus inverter KWh meters. Revenue grade is typically much more
accurate.</FONT> <BR><BR><FONT face=sans-serif size=2>Beyond that, even if the
accuracy of both was really good at lets say +/- 0.5%, you could still get a
1% overall difference in readings as one could be +0.5% and other -0.5%, even
though they are both working to spec.</FONT> <BR><BR><FONT face=sans-serif

<BR><BR><BR><FONT size=3>I recently installed a Solaredge 7600 inverter and
two feet away from it installed a GE 210 solar kWh utility grade meter. Over
the course of three months the kWh production measured by the inverter is more
than 200 kWh greater then the production showing on the GE meter. I
changed out the GE meter for the last week and the discrepancy has
continued, so it looks like it is not the meter.</FONT> <BR><FONT size=3>I am
looking for any help in understanding whey there is this large discrepancy on
the kWh reading between the inverter and the production meter, when they are
so close together. The Solaredge technical help desk has been of no
use.</FONT> <BR><BR><FONT size=3>-- </FONT><BR><FONT size=3>Kevin Eigel</FONT>
