Two Timed Discharge Periods

My fixed price deal with Octopus is shortly coming to an end and I am proposing to move onto the Octopus Flux plan:

Low rate import 02.00 - 05.00hrs
Peak rate import 16.00 - 19.00hrs

I have ASHP and Solar PV.

What I would like to do is set:

Timed Charge 02.00 - 05.00
Timed Discharge 07.00 - 10.00
Timed Discharge 16.00 - 19.00 (After the battery has topped up from PV)

Is that possible without me manually resetting timed discharge at the end of each period? If not what would be the best inverter settings to achieve my aims?

Davegreen1 you'd need to use something like GivTCP on Home Assistant or the Octopus Scheduler to do that.

But for the 0700-100 discharge, do you mean export to the grid or do you mean use by the home?

Davegreen1 Looking at this post, as @justpassing says, it looks like you need timed charge for 02:00 - 05:00 and Timed Discharge for 05:00-02:00 with a Timed Export 16:00-19:00. Not sure if you can overlay a timed export on top of a timed discharge and this may not work with your inverter. Also, I read somewhere (from @TheDragon (GivEnergy) I think) that there is a better scheduler with more timeslots available in the pipeline.

Home automation or Octopus can sort the issue, but if this does work with your inverter, or you can wait for the new Givenergy scheduler, it'd also be a solution.

Timed Charge 02.00 - 05.00
Timed Discharge 07.00 - 10.00
Timed Discharge 16.00 - 19.00 (After the battery has topped up from PV)

Why did you want the 7 to 10 discharge ?

On my system at least ( there seems to be some differences between experiences with this. so your milage may vary),
you could do:

Timed Charge 02.00 - 05.00

Timed Discharge 16.00 - 19.00 (After the battery has topped up from PV).

Would give you full battery at 5.00, run on battery till sunrise, then "eco behaviour" till 16:00, then start to attempt to max out the inverter AC from PV and battery till 19:00, or when your battery goes flat.

What I dont like about this for flux set and forget, is that if you cant set a battery minimum soc to preserve some of the battery during the 16-00 - 19:00 window, because it is a single value for both inside and outside that time. So if you did hit that limit, then the battery would retain charge, but not use it at any other time till the soc limit was manually reduced.

You can restrict the window to say 17:30 to 19:00, so that you "usually" have some charge left at 19:00, or try one of the automation options.

A fairly simple automation that only plays with that soc limit could be set up with HA or similar, leaving the inverter itself to do all the rest of the work, but once you need HA for part of the work, it might as well do all of it.

Tim, Cdent justpassing, Thanks for your help. Your advice did make me revisit my (perhaps naïve) logic for the 07.00 - 10.00 discharge (to the home) option, which was to use the low rated import energy to discharge the battery once the standard import rate became effective and then recharge the battery from solar for free. A re-look at the Flux tariff and the Day Rate export rate being higher than the Low Rate import rate would seem to make that discharge period unnecessary. Once the current deal expires experience will help me judge where to go next with the improved scheduler mentioned making the best options easier to implement as well. There probably needs to be differing strategies for summer and winter.
