Is there any benefit to running the Powerwall in self-powered mode if I have 1:1 net metering? I have no time of use rates.

That is a good reason to use self-powered mode. We essentially did that between inspection and PTO (three months) except that we generally operated off-grid during the day and turned the grid on either for the evening or overnight since our system does not cover our use. It was good to get a feel for what our usage is like and what we would need to do in an outage. (This can also be done as a paper exercise, but it doesn't have the same impact, and it also won't catch any problems with the system as a real test will.) To me it is worth occasionally testing with the grid off (truly self-powered) to make sure everything is working for if and when it is needed.I have 1:1 net metering here in Iowa. However, since this is my first year with one Powerwall and a tiny solar array, I want to know how I use energy and how the Tesla system works. Except for impending bad weather, I've stuck with self-powered mode. As a small example of the cost of doing this: From yesterday's energy usage, 12.2 kWh home, 9 kWh solar, 3.7 kWh from Powerwall, 4.4 kWh to Powerwall, 5.4 kWh from grid, 1.4 kWh to grid. Reserve set at 65%. (I've been moving the reserve around with the seasons.) The "to Powerwall" was all used up by 10:30 pm. If I lost 10% of my saved energy by diverting it from the grid, that's 0.44 kWh. At 9 cents per kWh, it cost 4 cents for the experience. So, maybe $9 for the year.
In a couple of months I'll switch to backup mode for all of the right reasons, including extending the battery life. For now, cheap and enlightening entertainment.
1:1 net metering. The dream.
I am here with 1:5 or 1:10 net metering. Makes it almost useless.
Are you on PG&E?
Solar NM1 folks, as I have a family member on, gets no TOU for 20 years with PGE
Yes. And I understand my original statement was incorrect much of the time.Are you on PG&E?
But that is even more advantageous to using Solar.
