[No longer] Going for a Givenergy 8.2 kWh AC Coupled battery

mickyduck55

I agree with @JKenH I don't expect my batteries to pay for themselves but as I have stated before I like the idea and certainly like the fact that I buy very little from the grid from March to October.  

I too am on FIT so the money spent on my batteries has been from my FIT payments.

We differ in one respect .. I did change my 500 W Plasma TV.. but I wanted a bigger one and it did irritate me that it consumed more electricity a day then any other device.

The 500w is not completely wasted in the winter ,

Maybe not, but unless mickyduck55 has found a gas-powered telly it will still cost more than a 100W TV plus 400W of GCH!

unless of course he binge watches in the early hours on Octopus Go

I have been looking at swapping my Panasonic plasma TV for LCD/OLED for the last 4 years when my new solar panels got me into watching consumption but it is still such a good TV I can’t bear to scrap it and at 50” is too big to go anywhere else. Part of my man maths case for buying the PPP was that it would cover the TV’s electricity usage. (The PPP isn’t wired in to the consumer unit so can only be used with devices that have a 3 pin plug.)

In an ideal world I would have a proper home storage battery (my DNO is the obstacle to that). Since I did my home energy audit my background consumption has dropped from around 7 kWh last year to 4.6 kWh this year and my import from 3kwh to 2 kWh this time of year. (Figures taken from myEnergi data both years while away on holiday). If the cost of a home storage battery was linear a small battery would provide the best return on investment as it could be cycled every day but of course it isn’t linear as there is the cost of the charge controller and inverter to be factored in so finding the sweet spot is a little more difficult but for some of us the optimum ROI (although perhaps still negative) would perhaps be a battery around 5kWh as for 6 months of the year we probably wouldn’t be able to use more than this.

Although 1080p/4K is a nice upgrade ,  the difference blew my mind when I first got my cheapish LCD tv(my pany was only HD ready). I wasn't even thinking about energy at the time , my Panasonic is connected to the birdbox now as I can't bring myself to chuck it.

True, you do notice the heat coming off the TV when you walk over to switch it off.

You are correct, I did often joke it was like having an electric fire mounted on the wall....
@JKenH mine is a 50" Panasonic, as you say a great TV...
My son says it has some residual value as it has plenty of old style connections e.g. SCART

I decided to get a battery to reduce my stress levels when my wife does the cooking and washing when the sun isn't shining. I also have the fun of working out how to maximise income from the agile Octopus.

How quickly does the battery respond on days when clouds are scudding across the sky and the sun is popping in and out? I ask because my iBoost lags a few seconds behind real time changes so for short periods and with a noticeable ramp up/down often ends up heating water after the sun disappears. Is it a similar problem with a battery?
