Renewables: "talking 'bout my generation"

I am wondering if it happened at the same time as the switch over from economy 7 to day rate electricity.

No logical reason why it should (but possibly lots of illogical ones !).

The changeover shouldn't interrupt electricity supply to property; it just alters which register of your meter is recording usage.

Sounds like a fault with the optiplug. Since you seem to have more than one, swapping them over sounds a good plan and if the symptoms go with the plug to another circuit you should ask for a replacement.

Seems unlikely - but not impossible ! - that some fault in your inverter is drawing a huge spike which the Wattson sensor interprets as generation hence switching immersion on.

Hi all. I'm back;)
Checked output on Sunny explorer 8th to 20th June.. it has "lumped" total together, 50 O's or 200kWh for 13 days????
21st = 1.33 O's
22nd = 4.15 O's:D

June so far = 383kWh. Just up on same date in June 2012:rotfl:

Thanks for the responses, useful suggestions and guidance with Holmes. Off on holiday tomorrow so must concentrate on that now. I will swop the plugs when I return..... and run the transmitter off the mains instead of batteries.

Running on batteries may be your problem; they only last about a month on high transmission rate; chances are they are close to depletion, if not depleted, change before you go on Hols. :rotfl:

Hiya Eric, tricky for me to do direct comparisons (till Aug) due to extension, but 82% last year equates to another 20kWh's against this years target, so hopefully safe after today/tomorrow.

Oh dear. Only got 7.3kWh's today, so yet to pass last years figure (proportionately). Fingers crossed for tomorrow. Month end estimate now down to 102%.

Forecast is really good, in fact the 9 day forecast is also great, with a solid sun, or a sun and white cloud for every single day. I've taken a screen image, so I can compare it to the longterm forecast tomorrow morning, when I expect it to be 9 days of grey and black clouds with lots of rain.

Not that I could do any better, with or without any lucky seaweed.

Edit: Still trying to work out 5 sec usage of 2kWh. Assuming 12p per kWh, must have a cost of £0.002p. So not too expensive. :rotfl:

That seemed hideously expensive at first glance and I presumed it was ten times out. A fifth of a penny every 5 seconds is 2.4p per minute, so the kWh you would consume after 30 minutes would cost 72p. Not sure how you managed to over estimate it sixfold

Hi

Re: "Still trying to work out 5 sec usage of 2kWh. Assuming 12p per kWh, must have a cost of £0.002p." related to the above .... the answer is actually impossible from the data given because it already relates to energy, not power, therefore time has already been applied and cannot logically be applied again.

You could calculate the cost of 5 seconds of usage of something consuming 2kW, but without knowing the timescale over which 2kWh is consumed you have no idea of the power being drawn, it could be 1 hour, in which case the answer would be 0.03p ((24p/3600)x5) -or- it could be 5 seconds in which case it would be 24p ! ....

Applying correct logic using time, power and cost to an appliance running for 5 seconds at an average power of 2000W, it would consume 2.78Wh ((5/3600)*2000) of energy which, at 12p/kWh, would cost 0.03p((2.78/1000)x12p).

S**t, why did I not think of it that way.. I assumed 1kWh was 12p/60minutes/60seconds * 5 seconds. We are being conned again! :rotfl:

2.4 O's today......

Thrashed you Eric by 0.1 O's.......

Expect K9 has gone on Hols.......oops K66 sorry.............

Yes, you should've used 24p, but your answer using 12p was still nowhere near half the correct answer.

£0.12p per kWh...5 seconds ?......

That's right. What's the big joke?

What a nice start to the day - I was completely wrong! The 8 day long term forecast this morning (length varies occasionally) is almost an exact match from last night. Sat onwards remains 4 days of solid sun (symbol), and the only change to tues - fri which were 4 days of sun with a white cloud, is that tues has changed to a solid sun.

Even if that weather doesn't arrive, still nice to have 2 forecasts in a row that are vaguely similar!

Come on last week of June, give me a '+' month! :cool2:
