Eco Mode / Octopus Go and EV charging

Fresh install of Solar, Inverter, and 9.5kWh battery and need help setting up the right modes.

Normally, I schedule the EV charging for the cheap rates between 00:30 and 04:30
What I want to do is maintain ECO mode so the battery reduces the demand on the grid at all other times.
What I find is happening - ECO mode recognises the increased demand when I charge the EV and basically fully discharges into the car each time I charge it.
This leaves me with battery close to zero and then pulling from the grid the next morning depending on solar generation.

What I really want to do is have the battery charge between 00:30 and 04:30 (especially in winter) to make use of the cheap rate as much as possible.
Then outside these times run in normal ECO mode.
I do not want the battery discharging into the EV when it is charging.

I think I could do this IF ECO mode was able to have a time period set like the other modes, but I cannot see an option to set this.

I hope I am making sense, and someone can help me with a solution

Thanks

The same question comes up a few times per week. Have a look through the forum and you will find the answer.

markgw Hi

On the dashboard go to your inverter card, click Settings, then Timed Charge. Set your Go times and a minimum battery % you want for your house. This time of year I set it to 100%. You will then charge both the EV and your 9.5kw from the grid.

As the weather improves you can move the slider down and if you have over that % that bit will discharge into your car.
