Octopus Free Power Hours
Re: Octopus Free Power Hours
Even though I didn't charge the car during the second half of the last power hour (I pulled the plug after the first couple of minutes in the first half hour because I was unsure what we'd be billed) the Octopus bill shows we were still on 7p/kWh.

You're correct it's IOG and IOF for car charging only.

They're not helping by taking away free power from everyone on IOG!
12x 340W JA Solar panels (4.08kWp)
3x 380W JA Solar panels (1.14kWp)
6x 2.4kWh Pylontech batteries (14.4kWh)
LuxPower inverter/charger
(Artist formally known as ******, well it should be obvious enough to those for whom such things are important.)

Re: Octopus Free Power Hours
My timing is prefect as usual. We have a Free Hour this PM but my Wifi has crashed between the PC and the Luxpower. It went down last Monday and changing both ends of the link, 100mts, has made no difference. It won't let me in via the Wifi Dongle and it was set to charge to 40% overnight before it went Tits up, and still is as I can't change the B**y thing. I'm currently waiting for an expensive engineer to sort it.

Re: Octopus Free Power Hours
Blast! I forgot about it... but I shall get half some of the benefit...
It would have been useful too, as it's grey here and a top-up before 4pm will be needed.

Re: Octopus Free Power Hours
Sorry to hear that AE M, we managed to use around 3.5kWh more than usual here so not masses but helpful.

Re: Octopus Free Power Hours
Well, I got a useful boost, but I'm still kicking myself. At least the sun has come out for a bit just now, so some of my export is coming directly off the roof and saving a bit of battery.
Hope your skies cheer up, I guess the trouble is that May and June have spoiled us!

Re: Octopus Free Power Hours
So I charged the Tesla at 2.4 kWh on a schedule and paused the batteries. Small house load over the car charging rate when the solar improved slightly.
First half use was 0.72 kWh 2nd half was 1.72kwh.
Let’s see what happens on the credit.
