Technical Support

I need some timer advice for how to buy/sell from/to grid. I have just moved over to Octopus Flux in the UK which offers reduced rates and a good sales price during set hours.

We have 7kw solar & 10kwh battery. we use about 60% battery on a very cloudy day, with 30-35% battery during peak hours so ill need to reserve that so I dont spend extra money. to start with I would like to buy an extra ~30% (3kw) during cheap period and sell ~30% (3kw) at peak period if above 50% charge, the basic table shows my plan.

How should I set up the timer to allow this buy/sell pattern since ive never used the timer for buying/selling before? and If there is a more cost efficient way id also love to know.
