Hopefully there tech department can shed some light on this for you, however, it would certainly be to SolarEdge's benefit to appear to be producing more power than it really is, well, unless, Hmmmm ..........

Revenue grade is typically much more accurate. 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.

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. 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. -- Kevin Eigel President Ecohouse Solar 1857 Northwest Blvd. Ste 201, Columbus, OH 43212 www,ecohousesolar.com 614-805-5776 ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service. _____________________________________________________________________________________________________________________ List sponsored by Redwood Alliance List Address: [email protected] Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/[email protected]/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org ------------------------------------------------------------------------------ _______________________________________________ List sponsored by Redwood Alliance List Address: [email protected] Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/[email protected]/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org
