    ..... not worth the paper it's written on ?


    True ;-)
    Its a pdf of a scan of a signed document ;-)


    One of the main conditions is that the battery has to be installed by a pylontech engineer. Thats me out unless I can find a way to become pylontech certified.
    Something I wouldnt mind looking at if there was an uptick in this sort of business.

    I was looking at 24kwh Leaf’s last night available under £6k with about 30k miles on them which would make a cheap home battery and no installation costs other than the the V2H charger. (I hope I understood that right). Presumably the charger would still attract a grant?

    If I was prepared to insure it I could have some free local motoring as well. That would probably work for you as well. I would still have to keep the diesel Golf for long runs though.

    Part 1 of the plan is in place; I‘ve bought a not so old Nissan Leaf. Collecting it Saturday. Now I can order a V2H charger.

    Would nearly be worth installing a 2nd connection and splitting the solar system if it affected fit etc. Would need to sit down and do the sums out, particularly as its only a trial in places.

    If you had the room or just broke the leaf that would nearly pay for it all.
    Interesting! Explains why some of the breaker prices for certain of the old batteries have increased.


    Last thing I need is another car but just about have the room (definitely room to break it - battery would go on an insulated wall in the garage), as you say just depends how cheap it would be to insure, limit mileage to about 2k a year....


    Going back to the pylontechs and nicks comment here or in the bev thread, bottled it nick! Came back last night and it was over 20% so set min soc back to 20%

    From what I've read on the speakev thread, you lose the deemed export part of the fit but not the generation.
    Think my main concern would be how much of a hammering the battery might take.

    I'm a bit puzzled, why would you lose the deemed export? V2H is no different to a domestic battery system.

    That was mentioned on the OVO V2G trial thread.
    I wasn't aware V2H was available yet ??

    Presumably because OVO pay you for the export instead.

    Is this scheme V2G as well as V2H? If so, I can understand the loss of deemed export.

    I use a different company for FIT payments to minimise the risk of moving to metered export. It'll still take another 5 years of batteries to get my overall export down to 50%.

    The 2 year trial is V2G with the possibility of allowing you to use the charger for V2H thereafter but nothing confirmed yet.
