New Octopus tariff for solar and battery users - Octopus Flux

It will be interesting to see how long the export takes to move from Outgoing Agile.

My Octopus account is now showing Flux export. So that is the next working day after I made my application. It suggests that a human is required to click something to switch the export, rather than the system automatically make the switch as it seemed to do for the import.

(Apologies for quoting myself, it seemed the easiest way to link my two statements)

Received my first Flux export payment on the 8th April.

12th March - 7th April average 239.4 kWh @ 24.55 = £58.78, on the old Go rate I used to receive a measly £9.81

Thank you. Now you've said it, I think I have seen that mentioned elsewhere in this forum - just not this conversation!

I have avoided Octopus watch for a while as I'd always thought it an app for a wearable product (a watch!). I am now realising I was wrong and "watch" is used as a verb! 

I also thought the same initially! The app is excellent. The developer is also very responsive and helpful. They have fixed issues live where I’ve had problems with try tariff on Octopus API.

My export is supposed to have gone live today, so now I wait in anticipation to see if I get paid for the 32kWh I exported.

Some indications of it being live are starting to show on the Octopus website, so hopefully tomorrow it will show my exports.

Loving this tariff and certainly looking forward to much longer sunnier days.

Where is this data display from? Is it the Octopus app?

It's an app called Octopus Watch. £1.99 on Android and iOS.

Sorry, this is probably the wrong place to say this, but I am loving the Octopus Watch app! I am having a bit of a geek out over my historical data and am particularly enjoying the before Flux and After Flux comparisons. (Not particularly fair as the sun has been doing the hokey cokey this week).

Really is a game changer that app. I always look forward to seeing what I did the day before! Also my averages over the past 7,14,28,and 120 days.

I think you are right about it being a game changer. It shows me data in a format that I think will make a huge difference to my ability to save money with Flux. (I think it would have with my previous rates as well)

Anyone care to go into detail what happens to their import/export/battery timeline?
I'm particularly interested what your battery does from sun up to sun down.

The settings I currently have are

So at 5AM the battery is 100% charged with the cheap rate Flux. It then slowly discharges until the sun comes out and PV output exceeds the load and any excess is exported. If we run a high load (e.g. kettle) then it will take some from the battery if needed. In the evening as PV drops, the battery starts discharging again. One thing that is useful with the Huawei inverter is that when PV output exceeds the inverter capacity (3.68kW in your setup) the excess is used to charge the battery (if not at 100%). Therefore you won't get clipping of generation. See below example for today:

Very briefly the output of the panels exceeded 5.5kW at around 11AM today, so the excess was fed to the batteries. Here's the PV and consumption from today as well:

I don't bother with exporting from the batteries at the higher evening rate; I'm not sure the difference is worth it when considering the impact it might have on battery life. I know others disagree, which is fine.

Hope this is of interest.

I also charge my battery between 2 and 5am, then run off battery until solar kicks in, which finishes charging the battery, and any excess is exported. I do force discharge some at peak time, but keep enough back to last until 2am.

I'm adding a second 14.5kW battery soon, so will export more at peak rate, I can charge at 8kW in the cheap period, currently only using 4kW for charging.
