I don't understand some of the details, but this sounded right when Jack Rikard (RIP) published it in 2018.

To deal with the utility grid is very simple – simply cut the cord and go off-grid. But this has some problems of its own.
Everyone knows that the solar energy available varies with the season. But few realize how MUCH it varies. We can produce 3.5x MORE electricity here in Missouri in June than we can in December from the same installed hardware.
And smaller weather events also pose a variable. Four days of rain cuts our power to the bone. Four days of sun and we have more than we can store or use.
And so for the present, we advocate maintaining a link to the grid. But we advocate you remain under the utility grid radar by simply maintaining a basic 200A 240vac link to the grid and paying the monthly minimum connection fee. Do NOT seek a “net metering” agreement or do anything to alert them that you are anything but a very low usage residential or commercial customer.
As it is QUITE common to have empty houses or apartments or dark warehouses for months or years, they really don’t have much in the way of tools to DETECT that you don’t use much electricity – as long as you pay that $11.24 connection fee every month. And you quite likely need to have a grid connection just for local code compliance.
And so you should have one. And use it as little as possible as a backup to augment your power system.
So we’ve inverted the usual scenario. Instead of a battery back up system for grid power, we envision a grid backed up battery system.
And we advocate abandoning the kumbayah vision of everybody sharing and loving each other. Do NOT seek net metering or compensation from the grid operator.
We call this SELFISH SOLAR. And of course the end mission remains the same – total independence from the grid ultimately. And we further see it as based on repurposed EV batteries for solar energy storage.

Maybe hard to fly under the radar if you're already on it?
