    Sticking with the topic of drink (nobody was talking about drink, but keep going Mart, just play it casual) I probably owe the Kernel a pint or two for starting this thread. An oasis of calm, to distract me from the panel thread, and give me an opportunity to re-arm my pram with more toys. :whistle:

    Today looked really good on the forecast, massive great big sun shining away at me - sadly though it was only from the hourly table on the weather report. Outside looked suspiciously different.

    Got 12.5, but thought I'd be over the daily target of 15 not under. Oh well, behind already, so yet another month of playing catchup!

    At first glance I missed the decimal point on Oscar's post, for a moment there I thought he'd given up on PV and gone nuclear instead. ;)

    I knew I should have put a comma in there instead of the full stop. :rotfl:

    Back in the game:j 13.0000 kWh today, bring it on :D:rotfl:
    Hope that rubs off on your system Shafeeq:beer:

    Oscar, all joking aside, how do you get readings to 4 decimal places. My new TGM has one decimal place, and my older TGM is extremely accurate to exactly no decimal places.

    My inverters are all over the place. The SB2500HF is 1% under, the SB1200 is 3% under, and the SE2200 is (approx as early days) about 1% over.

    Maybe the old TGM is over reading, and the new one is under reading and the PV is right? Maybe .... I'll shut up now!

    There may be a clue in that conclusion Kev. :rotfl:

    All joking aside Mart, which is rare in my case.......:rotfl:

    From what I gather, all GM are pre tested for accuracy, hence the reason they never have exactly 0 on the meter when they are new. It's a fact that inverter counters are not accurate in any consistant shape or form. This is why we must have a GM installed from the onset. As KevinG pointed out, the clue is in the conversion; seriously though the reading was 13.0 or 13.0000000000. :D

    See what that 'panel thread' can do in distracting your sense of humour......;) :) Did you get your e-mail ? :rotfl:

    Hiya Oscar, got the e-mail, but I don't think I should go for any more extensions, especially that kind.

    Oops, did you mean the other e-mail, must have had my Stella goggles on. :o

    I'd never thought about why both TGM's had a bit on them, just over 1 I think. Well you learn something new everything day. I've said it before and I'll say it again, in 10 years time we'll all know what we're doing with this PV stuff.

    Forecast looking good for the next 5 days, I keep saying it, but it keeps moving away one day every 24hrs, a bit like a carrot in front of a donkey.

    I'm leaving the panel thread to Blossom for a while. She seems to love taunting Cardew, very much tongue in cheek. It makes him play all innocent every time 'they don't like it up em'. Eventually he'll work it out!

    Maybe Kevin he stood next to the inverter, then flicked the isolator dead on 13. A modern day version of the stopwatch game from school!

    No. Nobody. Just me then. Well, when old(er) people like me went to school, we didn't have computer games, and smart phones to play with, so we'd all huddle around the 'rich' kid with a decimal watch and take turns trying to stop it as close to 10.00 sec each time. Was it fun, well probably equates to playing FIFA on the games console, or ball in a cup.

    What, nobody knows ball in a cup either, where you have a ball tied to a cup and you try to get the, oh hang on, it's time for my medicine

    Not too bad for 16:42 from a 2.5 kW system....:rotfl:

    Now that is the difference between a SSW facing system and an SSE facing system! I'm lucky to get more than a couple of hundred at that time.

    Edit: Mind you, having said that, I'm still getting about 200W now, which is pretty unusual.
