I have a question about EMONPI and Solar production after a certain time of day. For months now I’ve been Seeing Solar production in the positive and then reach zero after the sun goes down. Been that way since I set up the system.
I recently purchased a Solar battery and now I have 4 circuits connected to the battery for nighttime use. It’s not yet operational as the install still needs to be inspected. So my system is currently running as before but without the battery operational.
Now sometime around the late daytime, I’m seeing negative values coming from the Solar system which kind of messes with my numbers where before the values were at zero when the system was not producing. I checked the CT’s and they on the same lines at the breakers before the installation but they installed their own CT’s which are connected to the inverter for the monitoring.
My system is a SolarEdge 7600A-US with an LG Chem RESU10 battery. I’m kind of clueless on all this stuff so if this is normal and it’s a config issue or it’s an issue because the battery is not active yet that’s good too. Just curious why the negative numbers.
