<font size=2 face="sans-serif">Hi:</font>
<br>
<br><font size=2 face="sans-serif">The difference is in the accuracy of
revenue grade versus inverter KWh meters. Revenue grade is typically
much more accurate.</font>
<br>
<br><font size=2 face="sans-serif">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 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>
