    Just been entering my import/export readings for the last few weeks (I have been slacking off), and I haven't had anything for the last couple of weeks.

    Week 27/7 - 39kWh
    Week 3/8 - 9kWh
    Week 10/8 - 0kWh
    Week 17/8 - 0kWh
    Week 24/8 - 0kWh



    Generation meter light is solid on.

    Anything I can do before I call the letting agent to have it inspected?

    Our weekly import has spiked to over £10/ week when it is usually less than £4.

    That's a brand new inverter with all the cost associated - I don't know your install details so I don't know if that would be appropriate for your case as it supports upto 2650W.

    A UK seller is selling for £589 ex VAT plus delivery

    As it's doing nothing apart from sitting on the floor in the garage, I'm not after mega bucks for it £50 squid plus carriage, or collect.

    That's a very generous offer, I may speak to the letting agent about it. Thank you.

    theboylard, I am in BA6 postcode area may I ask if you are anywhere close to me?

    Ah, not sure if it's appropriate then - massively over specced for your requirements!!

    You're in Glasto country, I'm East Midlands. it's about 3hrs by car.
    From you - M5 north, M42 east, M6 south, A14 east.

    Offer still stands, but you may get more suitable equipment elsewhere?

    Yeah, I thought it was over specced. Wouldn't stop it working though I guess, and it's a very tempting price.

    Ok, so here is the latest skinny.

    The LA asked a solar man to come take a look at the inverter, and he confirmed that it has gone the way of the dodo.

    The LA has now had a quote for replacement, but they have asked me about the price. The man has quoted £600+ to fit either an Solax 1.5kW or Solis 1.5kW. The LA is concerned because they have looked up the cost of these inverters (I don't know where), and found them to be around the £300 mark. If that is correct then the LA believes that another £300 for fitting (which seems to be a simple task) is asking a bit much. I think I agree.

    The LA seems to like the SMA Sunnyboy 1.5kW unit I recommended, a lot more than the 'cheap' model offered by the solar man.

    I couldn't comment on the two inverters because I haven't heard of them.

    What are peoples thoughts?

    Also, they have an in-house electrician that they trust, and are thinking they would rather buy the inverter themselves and get him to fit. As another option.

    Interesting and I agree that if the inverter is really so cheap that £300 to fit is a bit steep. Only took my sparks half a day to dismantle my SMA 3000 inverter set-up and remount, then add the 1500 next to it, remake all circuits and test. My kit is in a fully floored attic.

    Therefore swapping out a dodo inverter should a couple of hours only...

    I have just randomly googled the SMA 1500 Sunny Boy and it shows £550 ex VAT (or 575€ inc VAT in Germany - don't you just love rip-off Britain?)

    That sounds about right for a couple of hours' work

    That's about what I thought as well. I think maybe the guy doesn't want the job, so just stuck in a high quote to cover the 'bother' of doing it.

    I think I may advise they just buy whatever inverter they like and get their in house guy to fit it.
