Solar with Battery - Winter alternatives to Octopus Flux ?

Comments

  • I'm going to give Flux a go over autum/winter and make use of the 18p rate which will mean I can use my battery for a while day quite easily.
    There's still a saving to be had for the 180 days(ish) I'll need it. 
    I absolutely can't be bothered to keep up with agile each day to schedule charging.
    If only there was an AI system that could do it all for you.......

  • First day of autumn today and Flux is still working for me with an export of £3.41 (1.7 kWhrs during peak), import: £2.35 elec / £1.01 gas and £0.75 standing charge. My September energy bill to date being £6.63
  • How big is your battery? Sorry if i have missed this detail... my battery is 11kw and last winter even on days when i had charged my battery overnight, if it was a very dull short winter day then my battery may have emptied by the afternoon and you could hit the afternoon peak rate! 
    I have changed to Go for now as I won't be exporting much now, but I'm supposed to be in outgoing lite which pays 8p/kw so that's better than the usual SEG rate...

    0 kWhrs! When bi-directional chargers start to hit the market next year I'll look into getting one with four wheels.

    My battery?
    It's only 10kw but my average daily usage in autumn- winter is <10kw so full battery plus some (even 2 or 3 kw) sunshine will be good to see me through.

  • Oct to Dec rates dropping by 8% which is very nice for topping up the battery.

  • Not according to the notification I’ve just received. The flux rate overnight that I can use to charge the battery/do washing etc. is higher than the day rate for normal use. It will be more expensive (only by 0.126p/KWh) than charging the battery during the day! The tarif I was on gave me 0.979p/KWh which helped with inverter losses.

    Well I did mean current Flux prices. 8% drop from the Jul-Sept prices.
    What tariff is it you're on?

  • Anyone have the E7 rates.. finding it difficult to find them on their webpage...( I know they differ by region but trying to decide if I should move from Flux)

    Flux import and flux export is how they are labelled in the app and on the notification. The export price during daytime off peak has gone from 18.948p to 16.185p. The import cost during the flux period overnight dropped from 17.969p to 16.311p making it more expensive to top up the battery overnight than during the day (not including inverter losses).
