[QUOTE="user 36882, post: 545538, member: 36882"] Thanks again for help all. CT is in good position and pointing in the right direction, but import/export to grid is still not accurate ( in fact barely showing anything). Really at a loss about what to do as installers don’t want to know and just tell me that our consumption must more or less the same, constantly, as solar production and battery - patently not the case e.g. yesterday smart meter registered 3.7kWh import and 13kWh export, but app/web server says zero or close to on both in same 24hr: [ATTACH type="full"]15500[/ATTACH] Faulty CT clamp? Wrongly wired? I noticed 2 import spikes, one when battery stopped discharging just after midnight and other just as solar would kick in ( sun first falls on roof just about then right now). Sorry for all the questions and observation that must seem basic to the knowledgeable, but I need to be sure I have a properly installed and functioning system. Thanks as always for any wisdom.
