[An Inspector Calls]

Also, as far as I know, there isn't a cancer cluster 'round my PV and nobody is trying to steal it to bomb someone, or break it up in situ to disrupt someone's livelihood.

You're implying, I assume, that there is around a nuclear power station. I suggest you debate that in the nuclear thread, it's irrelevant here.

the Owl meter in front of me is reading 2.55kW generation. Now the Owl is only a clip-on device

It's also a VI meter, not a true power meter; the V is also an assumed value.

Like I said, though it's accurate to better than 5%. The other meters are much more accurate but don't sit on the table in front of me. Now here's your last chance, acknowledge that you made an error or forever be designated troll status.

You've actually no idea what the error on an Owl meter is because you have no measure of phase angle - if you were an engineer you might be able to make a shrewd estimate but then . . .

Now here's your last chance, acknowledge that you made an error or forever be designated troll status.

Gosh, fear and trembling.


I presume you're referring to this post of yours

I'm sitting next to a meter which says we're generating 2.1kW just now. It's kinda like having a kettle on for hours but in reverse.

Really? It's a nice sunny day over there, but given that the average insolation for January/February is about 45 Wm^-2 (McKay, Sustainable Energy, page 38) then you must have either an installed area of 46 m^2 or a duff energy meter (it's not a VI meter, rather that an VIcosØ meter is it?)

Inspector, you have not corrected the errors in your post yet.

and before that

[Ah, now I know for certain you are talking absolute crap.

I haven't a clue what you're talking about. I doubt anyone else does either, since what I've posed is two questions which after some comprehension difficulty you managed to answer. It's difficult to see how a question can contain an error. So what error are you on about? All I can see is that the reference should be to page thirty eight and appears as 3 with a smiley but that seems to be a quirk of the editor.

I really think it's you that's talking crap, and this is becoming very tiresome - I think it's you that's the time-wasting troll.

That isn't a question, though there is a question within parenthesis. The sentence has no concluding punctuation mark but contains two alternative statements of fact that are both wrong:

you must have either an installed area of 46 m^2
or
a duff energy meter

I only have about 20 square metres and the meters are not duff.

How precious! Chop the question mark off the preceeding "Really?" to sustain your argument.

My area calculation encapsulates my surprise that your output (and thus area) was so large, which after reams and reams of drivel from you, turns out to be the case - thank you for finally answering that part of the question.

As for your Owl beind duff or not, well, it's got some numbers on it which are fun, perhaps useful for chasing down bits of stray consumption, but as I accurately surmised it is a VI meter. Very dubious for accurate power readings. Duff in my book. Oh, whoops, before I make another mistake for you to prat on about, it's actually a 240*I meter - it doesn't measure voltage.

Otherwise, what a waste of time and effort. All that effort just so that you can make these irrelevant points. What utter priffle! Grow up!

[Bandidoz]

I wouldn't expect there to be a really significant amount of reactive power in Biff's circuit there - bit of a moot point, really.

Now put your handbags away you two!

Back on topic - remember this guy?

Interesting first paragraph.
