Defo a narrowing of parameters for us. When i said to swmbo about the limits she immediately said plug the washing machine into the car this morning and run it down a bit. So I did!

I'm going to use this session for the hard part of a Blackcurrant Jam session. i.e. the sustained boil at temp >= 104 deg C.
I'll set the inverter to Charge the battery, which is already 100%-ish. This is intended to stop the battery discharging and ensure the full load is taken from GRID.
Hot jam burns are inevitable , but the results are far better than any shop product.

it has turned out to be ideal for me to charge my battery, as I did a full export 4 to 7 pm yesterday and today has been overcast so far, I'm only back up to 53% now! Should be able to export full bore again this evening after this...

I wonder if between 2-3pm all household electricity is charged at peak rate or the off peak rate it normally is when you charge the car and get a slot?
Would be quite sneaky of octopus and a revenge attack on the ones who game a slot.
Let you charge for free for the hour that usually costs 7p/kWh and use loads of electricity in that hour while it's charging cos all usage is then 7pkWh.
But... Then charge you for all other electricity you use at 30p/kWh in that hour and just get the car charging for free!
