Was told about these the other day. Plug in to any household socket, charges at night on cheaper rate, then use during the day when rate is higher.

Octopus do a cube summot or other. Anyone with more info. ??

The Tesla Powerwall is quite popular.

Some EVs do it too, you can charge them up at night, then let them power the house during the day.

Where's Dazzler when you need him, his rents do it, in fact i think they even sold some of the power back to the grid.

and you csn add batteries to some, stack em up. But you do need the right tariff, mines currently a flat rate. I've just swapped to Fuse energy so not sure what they do tbh.

Most energy suppliers off EV charging tariffs with a cheap overnight rate, you don't have to prove you've got an EV.

Some (like octopus) offer that and intelligent charging where you pay the cheaper rate when they feel like charging the EV (you give them control of the EV or the charger) which is obviously not suitable for the house battery.

But beware, cheap overnight rates often come with a slightly higher day rate.

I've looked at this and it's not cheap, it would take a long time to break even IF energy providers keep giving the discounts.
They would make more sense with a solar array but at the same time it makes a solar array less attractive.

Every option I look at fails to pass scrutiny, the only way I see me investing in green energy is when it's part of something else. If my roof needs replacing I'd get solar at the same time, if I got an electric car then an extra battery may help if I'm able to charge both on the cheap rate.
I want an air to air heat pump but the government only want us to have the inferior air to water (radiators) version. That might make a battery worthwhile but only if the attractive discounts last.

I'll probably just get plug in solar when it's available, it will have a much better ROI than bigger projects.
