Renewables: "talking 'bout my generation"

Happy Birthday to my panels :T:j

Scores on the Board :

My first Hawaii of the year today 20.5 kWh = 5.1 O's.

Total production for the year = 4019.3kWh.

Total elec used = 2933kWh (down from 5517 prev yr)
Total gas used = 5456 kWh ( down from 11232 prev yr).

Gas usage has reduced mainly due to being more mindful of when and how high I put the heating on for. Also I purchased a dehumidifier to use in my utility room, rather than dry the washing on the radiators. This has also meant not having to put heating on so much in winter.

all in all I'm chuffed with my first year:D

First Hawaii of the year! Best day since 04 Aug 2014

Ended the day with 5.62 O's (22.32 kWh)

Wow! looking at all these high numbers I'm spooning at the mo:eek:

3.75 O's here on the E. Coast:)

Best day for almost 6 months (12th Sept):T

3.88 O's today

Dishwasher then washing machine on, 2.4kw Leccy chainsaw on the go to cut up a load of waste wood for the wood burning stove and 7kwh dumped to hot water by I-boost.

15,500 Wh / 3,780 Wh = 4 Os


First day of Wattson records 16,210 Wh so there is a discrepancy.

3.62 Os here in east Scotland.

There always will be with any clamp on power meter. It can't allow for variations in the mains voltage. Yours is 5% out, which isn't too bad.

Looking at the forecast, my first Hawaii of 2015 is a while off yet! Lousy day tomorrow, no good days in the foreseeable forecast down here.

Better split mine down a bit
SSW 5 O's(didn't get one last March)
ESE 4.3 O's
WNW 2 O's
Total 23.4kWh or combined 3.6 O's

Quotations from: Diydykoto web site:

Check the firmware version of the Monitor; Wattson is generally within 5% accuracy that is assuming the voltage is 230V and the power factor is 1. Generally ones household in the U.K. has a supply voltage of 230V but varies up to 240V. So if your electrical voltage supply varies, the readings on your wattson will be less accurate.

Also wattson is based on a power factor = 1, (http://en.wikipedia.org/wiki/Power_factor) this means that appliances and devices such as fluorescent lights, switch mode power supplies; induction motors etc. which do not have a power factor of 1 will also cause the readings of wattson to be less accurate.

Note: Due to the way wattson measures power (Hall effect) any power readings below 40W will be inaccurate as their is not sufficient current flowing through the cable to generate a large enough magnetic field.

We have had some users report similar incidents and some have managed to find that their meters are inaccurate, however due to the nature of the wattson measurement methods, it cannot be used to prove your electrical meter is inaccurate.

In saying that, (as you have already done) testing your wattson by switching off all your appliances and switching on one appliance such as an electric heater or a halogen floodlight which have a power rating greater than 100W should yield a wattson reading that is within 5% of the power rating of the appliance. This should give you a good indication whether your electrical meter is inaccurate .

You can check what version of the firmware is on your Wattson. If the programming was successful, you should be able to read 'VERSION 10 - 4 - xxx' where xxx is the number of the latest version.

For now the latest available version is 10-4-420

To check the version:
1- Press and hold the button on Wattson for 5 seconds. It will say "Good Bye" then it will switch off, but keep o pressing till you get "Settings" on the screen.
2- On Setting the first category you will get is "Lang" (Languages). Tilt the Wattson to the back twice till you get "About"
3- When you get "About" click the button to view.

Tough, very tough...A/an Hawaii + 0.04 O's for me....
