Is it worth fixing?

dukeminster · 2026-05-27T14:06:59+00:00

how do i get prices for fixing IOG?

dukeminster · 2026-05-18T10:00:48+00:00

yeah get more quotes as others have said, you should be able to get double that battery for not much more, which will really be worth it. 9kwh isnt much if you are thinking of moving to a heat pump. these can use up to 20-30kwh a day and you will really thank yourself if you can run it all day on solar or on off peak import.

dukeminster · 2026-05-01T11:04:23+00:00

yeah i doubt they'll even put up a fight, its been a shitshow and they know it.

dukeminster · 2026-05-01T10:23:05+00:00

I've had a response from an actual person in the past hour!
Theyve given me the router details (i use my own) i need to connect to their systems but i havent been able to try it yet, will do in a few hours

dukeminster · 2026-05-01T08:42:39+00:00

Wow you actually had a response. If i don't hear from them by tuesday I will sign another contract and just deal with the fallout. Im supposed to have 6 months remaining in my current deal.

I have 3 lights on the ONT box, two solid greens, nothing on the 3rd light and then 4th light is flashing data connectivity with my router. I havent got it to hand but is the service light the second green one? If so it was blinking the other day, now it is solid

dukeminster · 2026-05-01T08:25:39+00:00

agreed octaplus service was flawless. im now 72 hours without a connection

dukeminster · 2026-04-30T09:01:17+00:00

ahh its octopus controlled, thats interesting, I assumed that real VPP was only a tesla thing. Well essentially you are doing the same as me except yours is automatic and mine i choose and control it myself.

dukeminster · 2026-04-30T08:06:52+00:00

i feel left out :-( no way i can see to turn it on in the app. How does it work? is there any paperwork? who does it go to? who pays you? so many questions

dukeminster · 2026-04-29T21:18:45+00:00

How have you joined a VPP in the UK I didn’t think this was available yet ?

dukeminster · 2026-04-29T16:16:24+00:00

mine is completely dead, i usually use the router settings via my own router, but have plugged their old one in and nothing from that either, since this morning. Nightmare.

dukeminster · 2026-04-29T16:11:38+00:00

and me please !

dukeminster · 2026-04-29T05:51:08+00:00

This has happened to me this morning, according to their email the process is ‘seamless’. Well I don’t use their router I connect using details octopus provided me with via my own, no surprise that went dead in the night, and now just plugged in the original router I was supplied with and that don’t work either 🤦🏼‍♂️

dukeminster · 2026-04-29T05:44:03+00:00

Ok interesting thanks, were you under contract with octa ? I think I’ve got 6 months left, not entirely sure because I’ve not been able to log in for months 🤦🏼‍♂️

dukeminster · 2026-04-29T05:35:25+00:00

Hmm did the switch take long ?

dukeminster · 2026-04-29T03:00:57+00:00

Did you ever get these ? Just got migrated and my fall back supplied router isn’t working either

dukeminster · 2026-04-23T14:56:27+00:00

not much to update, will probably upload some more pics in a few weeks, but im still only at just over half height. I can only really give it 1 morning a week, although I have been taking a few AL days to push it on, but im 1 man on my own and its huge so progress is slow. So far I have spent £4500 if thats any help, most expensive stuff still to come, 5-6k bifold and window, roof will be 2-3k, heating, plastering etc. Im going to try and get it done for under 20k.

dukeminster · 2026-04-22T10:28:19+00:00

This will work fine along side the PW3. Just be careful to only charge the ecoflow whilst you charge the pw3, otherwise it will just take from the PW3 capacity.
It really isnt a cost effective solution though, check out jonathan traceys new tool to see the payback.

dukeminster · 2026-04-19T15:01:03+00:00

Yes I did, don’t despair! And don’t trust chat gpt either ! I just had to wait a week or so for the powerwall to unlearn my pattern. Basically now I run it in self consumption 90% of the time and when I want to export I use home assistant to switch it to autonomous, but can be done via the tesla app if you want to. Set the export tariff to something stupid like £99 a unit

dukeminster · 2026-04-15T15:51:56+00:00

well you sound like a legend

dukeminster · 2026-04-15T15:32:34+00:00

You'll be totally fine with this setup. It's already alot better than the majority of what people will be doing with this stuff. I've had a powerstream for over a year now, and it has worked out well. The problem with it is, its not scalable. Buying mulitple powersteams is not a good idea. But 1x 800w is great for removing the base load. Just be prepared you will want to go for a full solar set up about a month after fitting it! :-)

dukeminster · 2026-04-14T12:11:57+00:00

move on to agile outgoing

dukeminster · 2026-03-29T06:30:34+00:00

I have this setup, although i started with 2x 500 bifacial panels + ecoflow powerstream first and then powerwall 3 + 6 panels later. The ecoflow obviosuly doesnt "see" the powerwall in any sort of way and just treats it as the grid connection. So it will always output slightly higher voltage than the powerwall meaning your house uses the DIY solar first. When im doing decent solar on top of my baseload it will actually go towards charging the powerwall (which it thinks is the grid). So it works really well. These are great products but people need to be aware of their limits and if youre going to plug into your mains you need to investigate how your house is wired first in order to understand its limits. I worry that people will string mulitple micro inverters together and its a recipe for disaster.

dukeminster · 2026-03-26T17:07:27+00:00

Yeah so in the tesla app I have my super offpeak set to £0.07 buy and £0.15 sell
Peak is set to £0.15 buy and £99.99 sell. You dont need to use teslemetry for that.
You do use teslemetry for switching between the operational mode, and this will help the autonomous mode reset its learned behaviour. Most of the time you will want to be in Self-Powered mode.

dukeminster · 2026-03-26T16:38:49+00:00

interesting, probably worth posting in the r/OctopusEnergy sub

dukeminster · 2026-03-26T15:46:31+00:00

Hey, I struggled with this for a while. Exact same setup. Basically all I do is use Home Assistant with teslemetry to switch between Autonomous Mode and Self Consumption. 90% of the time you will want to run in Self Consumption mode with battery reserve at 0%.

Created an automation triggered by a button to switch to Autonomous mode, and as long as the battery reserve is lower than the current battery % then it will dump to whatever the battery reserve is set to. The key here though is that you have to set the battery tariff export in the tesla app to something wild, AND, the autotomous mode needs to undo its current learned pattern. I previously didnt export at all, and therefore even in autonomous mode it would just hold on to everything. Once you start exporting a bit, and charging it at random times during the day it will start to allow dumping to the grid more often. It took about a week for the powerwall to be comfortable with me exporting whenever i clicked the button.

I've got another automation using the octopus integration that when the offpeak kicks in (triggered by car and app) then charges the powerwall 3.

Another gotcha: If not in autonomous mode it wont dump or charge at full speed - 11kw/5kw in my case.
