[QUOTE="Rigger, post: 388590, member: 25950"] Ok - for clarification. I have two digital meters. One is a Yong Tai Long M12 digital meter for reading the generation straight off the the inverter tie-in from the PV array. At the other side is the Landis + Gyr E110 5235A meter that has been configured to give two readings - t for import and r for export. it automatically swithces between the T and R meter readings every few seconds. Binky - point taken about the meter not being configured correctly - we are all human after all. NIE have been contacted to make sure the meter is configured correctly. I've also checked some readings from today. Enphase system says that the panels have generated 15kW today - not great - but not bad. Checked against the generation meter, and it's not far off really. Then went and checked import export meter. readings earlier (9am) were t-1767 and r-507 T=import R = export from Solar PV array. Reading now (18:20) are t - 1768 and r 515. So - I'm figuring this means that the meter is not reading both export and import as one, and is able to register the flow direction, and meter it each way. [/QUOTE]
