Power company not accepting production power

I didn’t see everything he did, but the tape is still/back on there. He put it up as a safety measure since those lines carry 120vAC.

I agree with another poster about shutting down your consumption so you can see what happens with the data.
Just pick a time during the day when you can be without power for an hour or two, and throw the breakers for the house.
Get the car out of the garage, close the garage door, throw all the breakers, go out for a drive / shopping / lunch / whatever, come back 2 hours later, turn everything back on, and see what the data looks like. (And fix all the clocks that need to be fixed.)

Oh - and make sure the freezer and fridge are closed tight before you flip the breaker.
You might even want to set them to their coldest settings ~2 hours beforehand.
Or even freeze some extra ice and leave it in the fridge if you're going to be more than 2 hours without power.

FWIW, I've done something similar when I've gone on vacation for periods of 10 days-2 weeks or so by opening all the circuits in the panel except the one controlling the fridge and unplugging/dewiring everything else on that circuit, and then putting a kill-a- watt meter on the fridge. After doing that 4 times I estimate that my system monitor reads somewhere between ~~ 0.0035 and 0.0055 higher than my POCO meter.

I'll try that if swapping the Consumption Meter doesn't help, but honestly with how closely the consumption figure tracks the production figure I don't have much hope for that showing me anything useful. I really don't think I have a phantom 10kW load that only appears when the panels are active.

For reference about 2 months after making this post the inverter died outright. My installer replaced the inverter and that solved the problem.

It looks to me that this is either a mistake in the CTs placement, or in the programming of which CTs report what.

If the grid was not accepting power, then the solar production would not happen (or be limited) as power has to go somewhere. The fact you have full solar production curves, mean the grid is taking your solar production surplus (your billing also appear to confirm that).

So it looks like your grid export may be interpreted as Self consumption.

What you need from the installer is an accurate wiring schematic showing the various circuits, the CTs placement, and where they are connected on the Monitoring modules.
And not the theoretical schematic, the actual one on your install, and you should follow it yourself to make sure it is accurate.

It may be a moot point now, but just for ref I'll note here a post I made in another discussion about what happens where the L1 and L2 CTs are simply swapped. Had I known I could have done this fix myself I would have -- but my installer did it for me.
