Thanks This is really helpful. I will play with my spreadsheet again!

I am on the Tesla Energy Plan, which works really well for me, and am starting to prepare for the Octopus Flux scheme, which also looks good. I have started to try to gain a better understanding of the data which I can download from the App to see what else I can learn about how the system...

Thanks Fred. We are net exporters, having 2 arrays - the first is 3.84 declared net capacity facing SE, the second is 4.8 declared net capacity facing SW. From Dec 20th to Mar 19th 2022 we imported 1,196 and exported 1,189 - a net of just 6 Kw - less than £1. During this period we generated...

I call this the "waste" and I picture it as power which goes into the battery and never comes out again. I calculate it as (generated+import)-(export+used). For me, it averages out at about 1.6Kw per day. It is slightly higher in colder months than warmer months, I have no idea why. 1.6KW...

Just getting to the end of my second quarter with TEP. It works well for us. We are net exporters, having 2 arrays - the first is 3.84 declared net capacity facing SE, the second is 4.8 declared net capacity facing SW. These were installed in first and second year of FITT, so they have...

Just checked this evening and it has got worse. Now it is showing zero for incoming and outgoing on the App and in the data download. Oddly, the graphs still look accurate, which makes no sense.

I have had a problem since Friday 2nd July, when the "From Grid" figure in the App seemed to match the Graph in the App. On the Saturday, the "From Grid" figure looked much lower than the Graph and since then, the "From Grid" figure has been zero, even though it is showing use on the Graph...

Hi Thanks fo this confirmation. The reason that I decided to go for TEP is that I have 2 arrays, so the difference between the income that I receive on the plan is much greater than I was getting through the deemed export amount. In reality, it looks like I am going to more than cover my gas...

Thanks John The pattern is really consistent now, virtually everyday. The battery is charged up every day by a mix of solar and grid, the mix does not really matter. The battery then sits full for a while and is then discharged to about 19%. I am still losing 1.6KWH everyday. One of my...

oops - that didn't work as planned! This is what I said on the other thread An update a few weeks in! I seem to be losing about 1.6Kw per day, consistently. Yesterday is a good example. I generated 27 and used 10.2 in the house leaving a net of 16.8. 23.8 went to the grid and 8.6 came back...

An update on various points. My electric smart meter now seems to be working in both directions. The readings in the Tesla App and the Octopus web reports match. However, Octopus have told me that the IHD will not be able to show export and import. They are still having a problem...

An update a few weeks in! I seem to be losing about 1.6Kw per day, consistently. Yesterday is a good example. I generated 27 and used 10.2 in the house leaving a net of 16.8. 23.8 went to the grid and 8.6 came back from the Grid a net of 15.2. So, my reckoning, 1.6 has got "lost" in the...

Still nothing to report. New meter still not visible for billing and IHD. With so little sun around, battery is sitting at 20% in reserve for most of the time.

New meter was installed on 3rd December, but the process of transferring to new meters and billing still open. Octopus told me it could take 2 months. Are others facing similar delays?

Got my refund from Octopus yesterday

Update is nothing to report really, My faulty meter was swapped out and now needs to be commissioned. I won't be able to see import and export until this is completed in the next week or so With so little sun is the last few days I have left the battery sitting with 5% in reserve and there is...

My meter was swapped out on Friday - Kaifa MA120 installed. Engineer reporting that he had been working away from home for a month just doing replacements. What an expensive fault this is proving to be for someone! Apparently, it will take a couple of weeks to be commissioned centrally and...

Will do! I am interested in how long you would define an extended period as being?

that is an interesting observation John. I think my value will be about £400 per year so thought it was worth a try. I will be looking to see how much they actually use the battery in the first year and then decide whether to continue.

Hi Mike No change at all in the App at the moment. I have turned off the Go time schedule and gone back to self powered mode with 0% reserve. There is no evidence of anything "new" happening to my import/export and the behaviour is unchanged. Hope that helps Cheers

Octopus updated my import and export end dates today at my request so that they co-terminate next year. They told me that the In House Display will catch up in the future to show the import and export separately. I am happy with the situation

Another update My Octopus page on the web allows me to see yesterday's imported units, button the exported ones

Hi John I suggest that you ask them specifically to start them together. Today, I have been a net exporter, but it is not showing on my internal monitor. I will look at the readings from the smart meter tomorrow. Good luck

An update - I am now live on both tariffs. The process has been straightforward, but confusing (for me) in two areas. I suspect Tesla see this as an "integrated" package, whereas, it seems to me, that Octopus have dealt with import and export as 2 separate things. So I moved onto the import...

That is very reassuring as I have had the same behaviour on my existing meter. My new meter is being installed later this month. I got the details of the compensation scheme yesterday and felt it was a very sensible and reasonable solution.. Again, well done Octopus

Had a "good news" message from Octopus today to tell me that my Import Tariff had been transfrerred and that my export tariff would follow when completed. However, there was no time line for this. I have replied that, unfortunately, as I am migrating from Go they have doubled the price of...

I can only compliment Octopus on their service. I sent them the mail from Tesla, they said that knew about it and have called me back today to set a swap over later this month.

Hi John I have also applied and just received the link to submit my details. Lets see how it unfolds! Cheers David

Thanks - yes I am on cost saving and StormWatch off, but I have the reserve set to zero. I have not experimented with changing the reserve figure. Cheers

Thanks Cuban Do you have your Advanced Setting on Balanced or Cost Saving? I only started using the TOU settings a couple of weeks ago, so maybe I have just not been patient enough. According to my App, in 2020 I have imported 420KW and exported 4,445KW, So a net export of over 4,000 Kw in...

I have been on the Octopus Go rate for a few months now and, like John, have become frustrated with the randomness of when it does and does not decide to charge overnight. This new Energy Plan looks like it will be beneficial as I can stop worrying about things like that. I am a net exporter...

I have had Powerwall for just over a month and can not see it in Tesla.com. Is the "Manage" functionality useful? Thanks

I have had a Gateway 2 for about a month. As Mike suggested, I was told by several installers in the UK that I could only have a 2. Even if I had been given the choice, I would have gone for a 2, not least because I hope it will give at least some level of future proofing for the many...

Tried an experiment yesterday evening with a reassuring outcome. When the SOC was around 75%, I set up the timing for 30 minutes of "off peak" to start 2 hours later with a reserve of 90% and in cost-saving mode. The battery started charging when the off peak period started, took the battery...

Thanks for all of the helpful replies. I have the new Gateway 2 and it does have the reserve level setting available in Advanced cost saving mode. It is much clearer to me now how the Cost Saving mode works, even if it is not optimised for UK weather. I suspect that I will need to see how it...

Hi all, a newbie here! I have been using solar since the first UK FIT scheme in 2011. I have 2 arrays and typically generate just over 8,000KWh per annum. My export tariff is based on 50% deemed export at 3.82p per KWh (ie about £150 per annum). I had a Powerwall with the new Gateway...
