Thanks
jjrandorin Great Info, much appreciated.
Sure, no problem at all.
If I was in your shoes, depending on my electricity plan, I would either setup time based controls (if on a TOU plan) or, consider setting a higher reserve. The reason I say that, is because (as alluded to by a couple others in this thread), your reserve is very low for someone with electricity usage you have.
If you were in an actual power outage, you could do things like turn off the pool pump, or run your AC only during the time the sun was shining (and obviously not charge your car), but with your reserve set so low, you wouldnt have too much time to react if you noticed there was an outage or something.
Self powered mode (which is what I also use) will prioritize using as little power from the grid as possible. Its a fairly simple mode. During the day, solar goes to power your home. Any left over after that goes to the powerwalls. Any left over after THAT goes back to the grid.
Still talking self powered mode here......
If an electrical load happens that can not be met by the solar being generated at the time that load starts, the excess will come from the powerwall. You can see this in your provided screenshots. If that load still can not be met between solar and powerwalls, then it will pull from the grid.
The advanced modes can be setup so that your system tries to get through that 4-9pm peak time on only powerwalls, but whether that is correct for you or not depends on your electrical plan, etc.
Anyway, since self powered mode will prioritize using as little from the grid as possible, even overnight, you will likely always draw down to your reserve. If you have your reserve set that low, and there is a power outage in the middle of the night, there is a real chance you might not have power in the powerwalls to cover it.
I personally use self powered mode because I am still on a tiered energy plan, where how much energy total matters, not when I use it. I am incentivized to keep my overall grid draw as low as possible, not just during peak time, but all the time.
The CA utilities dont allow solar users on these plans any longer, because you can basically keep yourself off grid most of the time from march to august or even longer, given an appropriate sized system, and use the grid as a big powerwall, effectively.
