Home Battery Storage

[Saleen836]

As I have eco7 here at home the thought of battery storage has been in my thoughts for a while, of course googling the subject means I get targeted adverts, some of which have prices which look pretty good, one (GroWatt) is advertising a fully installed 6.5kwh storage system for £2975, yes, a look deeper and the small print says only something like 10 of these available at this price but being such a low user (average 2-3kwh a day) I am wondering if it is even worth it due to the payback period.
Current rates are Day rate 28.52p per kWh Night rate 11.87p per kWh

Anyone gone this route?

I thought this thread was going to be about safe places to store the battery unit, ie, not in the house itself.

If you are genuinely only using 3 units a day you might save 50p. That’s £180 a year, so about 16 years to break even.
If prices rise (duh!) then you’ll get there quicker, but even so I wouldn’t bother.

Not bothering is the way I am leaning as the 3 units includes the cheap overnight rate (dishwasher & washing machine), the following is from a bill from Octopus.....

Estimated Annual
Usage (Day) 859.1 kWh
Estimated Annual
Usage (Night) 353.5 kWh

Did you see the word estimated in the bill?

I would have a check of what you are really using, before deciding.

Are you stuck with your current supplier? Much better night rates available (I'm on E7 with Utility Warehouse @ 5p overnight). That would reduce any payback period. Although with so little usage i doubt i'd bother in your situation.

I've got givEnergy batteries doing load shifting in this way (no solar), but I'm a much heavier user. I calculated my payback period at 6 years.

If you are only using 2-3kwh per day, and aren't trying to be off-grid, then I don't think it has any chance of being a worthwhile "investment"...

I have checked and as posted already I am using 2-3units a day

Agreed, the payback period for me as a very low user makes it not financially viable in the slightest, especially as I had an electrician I use to give me a quote, that came back at just over £4k making the payback period around 20years or more, as I expect in that time the battery will need replacing
