Micro grid use while in self-powed mode?

[bwb1]

I have a relativly new system - I added 4.08kW and 2 PW's to my existing 5.44kw system. While I'm still awaiting PTO on the new addition, the system is working in self-powed mode and exporting excess production to the grid as expected (presumedly capped at my original system capacity).

For the first month or so I took nothing from the grid, except for very rare micro blips, as all power was provided via solar and the PW's. However, for the past 3-4 weeks (after several app updates) the app is now showing that I'm drawing regular micro levels of kW's (see blue in chart below) eventhough my battery is charged and supplying power to the house. Sometimes it's spotty and other more consistent like in the image below. Is this normal? Why would it not be there for the first month and suddlenly show up?

Thanks in advance,

I think I resolved the issue. Onset was with the new TOU controls in the app a few weeks back, and I had swithched over and expirimented a bit with TOU but then switched back to self-powered. Maybe it was just a software glitch becuase yesterday I cycled to TOU and then back self-powered and everything appears to be working as expected now - no low level grid use.

Spoke too soon...it's back. I sent a note into Tesla and I'll wait to hear what they have to say.

I cant speak for anyone else, but I am following this thread. Please let us know what you find out, if anything. I didnt post because I didnt have any suggestions to offer, but am posting now so that you dont feel like you are talking into a room full of people who are not listening.

I wish I had more help to offer, but as my system is not installed I cannot speak from experience.

Do you have a whole home backup? What is your main panel like as far as the breakers inside it?

 

[bwb1]

@Vines - Yes, whole home backup. No additional loads or changes that could explain the sudden change in drawing small amounts of power from the grid.

Hmm, just guessing here but it could be a CT meter is going bad. Wish I could be more help. Please let us know what it turns out to be, once you get Tesla to solve this for you.

Last 2 days I also am having this issue. My Powerwall's are fully charged by the end of the day and can supply the house all night. I have noticed that during the night when everyone is asleep, (house is pulling only .6-.7 Kw) that there are micro pulls from the grid (.1Kw), even though the Powerwall's are capable of providing sufficient power.

I'm confused. How are you exporting anything to the grid in Self-consumption mode?

Yes, all excess production beyond my self-consumption needs and 100% state of charge to my PWs.
