Can’t get Powerwall 3 to do what i want.

Hey,

So I have a PW 3 and on E.on next drive V7 plan in the UK. I have been using Netzero app to manage my PW, but can’t justify the monthly fee. So now looking at how I can get the PW to charge the battery off peak 12AM-7AM, then between 7AM-12AM run the house on solar first, followed by battery.

I am using time based control. With all the figures as provided by my utility provider on rates. But the problem I have is the battery only charges to about 85% off peak from the grid, then during the day it exports all solar and uses the battery to run the house. By the time I get to the evening, I am close to my reserve and eventually using the grid at peak hours.

How can I set up my utility rate to do what i want as per above. My set up is as below:

Grid Charging ON PTO: ON Solar only

Super Off Peak - Buy: 0.06p - Sell: 0.17p Peak - Buy: 0.27p - Sell: 0.17p

Any help on this will be appreciated! TIA
