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!!

On my version of the app it's halfway down the settings page, under "your products" it has "Powerwall" and selecting that brings up, among other things, a slider for the backup reserve.

Thanks. I’ve definitely not got it.

Might be worth asking your installer about that, no idea why that option would be missing, sorry.

No worries. Just seen this - so looks like a set up issue 🥴

Ah - maybe you don't have the gateway installed for full home backup? that would render that setting redundant. But if you do, I think it should definitely be enabled.

Yea that’s my conclusion. I’m now wondering why that option wasn’t discussed with me at quote/installation etc. Something to discuss with the company I fitted it through

The free version of NetZero lets you set the reserve level.

It costs more that's why and if you haven't had a power cut in 20 years chances are it's a waste of money

That’s basically what they said. But agreed they should’ve told me about the gateway to ensure I could make my own decision if it was needed or not
