4.2kWh turnkey for £3,200. I'm sure how I feel about such a low capacity
4.2kWh currently costs less than 60p to buy at peak, so may save 30p a day unless you're topping up from solar. And is it really enough to power your house after dark.
Interesting all the same so thanks for sharing. A good to see companies moving into this space.

It's an interesting proposition, but unless you have a whopping great solar array, doesn't make a great deal of sense at the price.
For £200 or so, you can get a box that dumps all the excess power from your solar array into the immersion heater. For 6 months of the year it provides a bit of a kick to the water temperature, and in the 6 brighter months, it runs the hot water pretty easily. Right now, ours is just about heating a tank of water, assuming a bright sunny day and nothing else drawing power in the house. In high summer it will easily heat the hot water and have power to spare.
So for about 3 months of the year, this battery will give you enough power to run the lights, telly and playstation for most of the evening. Maybe saving you 30p a day, or about £90 a year. Not a great rate of return.
Assuming it lasts for longer than its 2 year warranty, the immersion heater thingy will be a good investment at £200. £3,600 of secondhand batteries and an inverter will need to last 20 years....

RRP is £300, new ones appear on eBay for less.
It does what it says on the tin. I put ours in a month ago, it has saved a whopping £2 so far, but I am expecting zero hot water bills in April - September.
That battery thing may make more sense in Arizona where you get proper sunlight all year - probably only a 10 year payback. But to start going "off grid" in the U.K you'd need a 30 kW solar installation to get through the winter...

Unfortunately we need a complete reversal of the current system, where people charge at home from the grid overnight (pretty much meaning it's mostly fossil fuel based generation), then drive to work and leave their car parked all day in the sun, not charging!
If the government gave companies tax incentives to install solar arrays, we could charge our cars whilst they stood idle all day, then take the excess power home, plug into our house, and run our house over night from the car!
