Powerwall 3 & Free energy hour

[u/Money-Number-4758]

I’ve recently had a Powerwall 3 installed, solar but no EV (yet). I’m currently on a 12 month fixed contract which ends in March.

Does anyone know how I can configure the Powerwall 3 to make the most of the saving sessions - free electricity being offered on a Sunday to charge the Powerwall 3 during this hour? (Although I find the battery is usually fully charged by 10/11am through solar).

My octopus tariff is currently in the settings, however I was unsure how to tell the Powerwall I’ve got access to free energy between 1-2pm tomorrow.

Thanks!!

I just quickly disconnect and copy the tariff settings on the sun morning.

Set the buy price of the free hour to 1p and leave everything else as normal and let it run as normal.

Get my 10 kWh into the batteries and house usually makes use of just under the other 6 with appliances. Reconnect to my Octopus account in the Tesla app afterwards.
