The Octopus x Tesla Powerwall 3 Collaboration: A Game-Changer for UK homeowners?

Informative and interesting, but please please please drop the background music. Please.

Thanks, I am a big fan of Octopus and their smart tariffs. This Tesla powerwall will obviously suit some users, but not for me. It is too big for me in the UK, in Summer my battery fills before noon and then exports, which is not too bad, in Winter I am lucky to get 2-3Kwh from solar and the battery will never fill, but yes, charge it up overnight on cheap rate and use what you have during the day, but very hard to justify a big battery just to see you through 4 months of low generation on the basis of cheap overnight rate. Some users with heat pumps etc and high daily usage, then yes, but be careful buying a battery that is too big for your use case.

I’d want bigger inverter than 5kw.I do like my electric shower.and if I wish to go down the route of replacing gas for all electric I’d definitely want a lot more.

In your summary, you didn't call out the discharge rate difference. With the bigger appliances drawing 3kW each and used at the same time, I'm thinking oven and induction hob, this could keep more if not all of the load off grid using the PW3.

I am a little confused. I have a powerwall II for years and was on an Octopus Tariff in conjunction with Tesla a couple of years ago. This abruptly terminated when Tesla decided to start their on UK based Energy supply company?

Does that Octopus Tariff mean that between 4pm & 7pm I can’t use my own battery storage power? E.g. forced to pay the premium price?

Great effort, but, for God’s sake, get rid of the background music! It only serves to make it more difficult to understand you. The hard of hearing, of whom I am one, find it difficult to distinguish between two or more sound sources. You don’t need the background noise.

Save yourself a ton of of money and get a GivEnergy AIO it’s far cheaper and has the integration already there, just cos it has a Tesla badge doesn’t mean it’s the bet, do t believe the hype.

You can't trust octopus, they announced that they were going to offer feed in tariffs to people who had solar pv but were not mcs certified. Well that game changer promptly died a death, i am guessing due to pressure from the red tape bureau or the MCS, who were concerned their gravy train could end.

I just priced up a system and they told me it was a 13 year ROI which matches my own conclusion as on Octopus Intelligent I’m averaging about 18 pence per KwH for my electric. I use about 20 kWh a day without the car. Until ROI is down to about 5 years it makes no financial sense. I can put the £12k or so in investments and get around 10% in a decent fund. I’m hoping Labour see the benefit to this and allow you to write it off against your income tax. Your calculations are nothing like reality on the import tariffs. As I say I am currently averaging 18 pence and only usually charge the car once a week. So substantially increase that. Plus your calculations take no account of the time cost of money and investment returns. There’s no business case for buying these currently unfortunately.

VAT is only zero if installed with solar
