Targeting EV but also home storage.

That website is VERY short on details, and no prices.

Yet another on the bandwagon. Yet more early adopter gambling!

My biggest issue is "will the one you choose still be there to honor any warranty?".

Shades of solar power companies.

 

Go local. Go with solid people. Get an insurance based warranty if available. Don't go for the absolute cheapest.

You only have to run the numbers to realise there is no merit in having a battery power pack at home yet.  Maybe one day it will be viable.

Just remember that you can, if you shop around, buy a unit of power for about 13p, and if you are storing power, then on E7 it is less than 9p.

 

So take my house that uses 4000 kWh, with 80% on E7, that is £288/year.

If these power packs really can last 10 years, that is £2880 installed to break even.

And that is assuming they can survive 3650 charge/discharge cycles and deliver a decent amount of power (say enough to boil a kettle).

 

At the moment my storage is a 29 year old, 200 lt water cylinder on the original element and thermostat.  It can hold about 10 kWh of energy, deliver power at 60 kW, has an efficiency of about 75% and would cost less that £300 to replace.
