Hi. My system has been working perfectly since it was installed at the end of January this year. I am on Octopus Intelligent Flux. I did a battery software update last week and since then I have seen my battery dropping to as low as 5%. The settings in my portal are to not drop below 20%. I only have 80% useable capacity with a Gen 1 5.2 KWh battery. I’ve been in touch with Octopus and they say that their settings are inline with my 20% and when they have been exporting I can see that their settings state 20%. I now dont know what to do. Can anyone advise please?

IOF - you give control to octopus, octopus will do whatever they want.
They always used to take my battery down to circa 20% but in the last week or so have started to go down to circa 6%.

Thanks, Have you done the software update in the past week? Its only since the software update that this has happened.
No, I’ve not upgraded recently

Looking at this graph, it appears (to me) that your battery is being discharged beyond 20% and then being recharged back up to above 20% a short time later.
I wonder whether IOF is starting a discharge and waiting for it to reach 20%, but the polling is too slow, so it is reaching a much lower soc before the Octopus server spots it. It is then having to recharge you battery (at a time when the grid needs the energy) to correct it and avoid your battery running flat.
It’s difficult to see on that resolution, just looked at last week, it charges to 20% at 11pm each time. So it is well outside of the peak.
I think it’s a good idea to put a bit of charge in the battery, e.g. in case of a power cut, but perhaps charging it at say 8pm might be better - even if it did it slowly.
That’s even worse (for you) because it means that rather than discharging to 20%, leaving you enough energy to run your house on, it is running your battery flat, forcing you to run your house from grid at peak rate.
My baseload is low and I try to avoid using high power equipment during peak. E.g. I’ll cook whilst it’s discharging rather than when it’s empty.
Get more money that way too so it’s swings and roundabouts.
