I switched to EV-TOU2 plan in August where peak is now 4p-9p. I expected PW to charge from solar, then cover the peak period. Typically, we do not use a lot of power during peak. House consumes about 1 KW per hour, give or take. Average 5kwh. Some days we use the oven which will bump that, but 5 kwh is average. Obviously, 5kwh is nothing for 2 PW's. The system started getting "smart" and stopped topping off the PW choosing to export more solar to the grid. Whatever, it is doing its thing.
Then the heat wave came.
I adjusted the reserve when it started warming so the PW's would charge to 100% to cover the AC during peak. AC ran for maybe 10 days with PW charging to 100% and nearly down to 20% (Reserve) by 9pm. Then the heat wave passed, PW kept charging to 100% afterwards and I stopped paying attention daily.
It's warming up again. I expected to have to run AC next week, but it got to 90 today and I turned on the AC at 1p or so. Didn't even think to check the PW in the app. At 4:15, I saw PW was down to 79%. I look at the history and the PW did not top off last night, but it did the the previous 7 days. It only started charging at 3p today when I turned on the oven and didn't get far until peak hit.
Is there any tweaks to encourage the PW to top off daily? I'd prefer to have enough power to run the AC in the event we need to. Most of the year we do not run the AC, but the Aug/Sept and into Oct can be a bit warm or muggy historically.
thanks.
