Probably yes. Actually no
The cost far outweighs the benefit for me
Also I can’t run an electric shower off a battery

You could probably run it from the combined output of your car at 7kw and a fixed static storage battery at 3.6kw unless it’s a very powerful one.
You probably wouldn’t install a static storage battery without solar anyway and the additional cost of installing 5kwh battery to a solar not significant these days.
A hybrid inverter is lightly more expensive than a standard one and the cost of the battery itself. 99% of the work is already done as part of the solar install.
Obvious small EV ones are the Up/mii/citygo variants, I have an Up (petrol GTi) surprisingly practical car, if you carry more than 2 in the car more so than a Mini or 500 despite being tiny. Things like the Zoe and Leaf are a fair bit larger.
Hard thing to answer small petrol or EV, I would imagine EV should be the better prospect for low mileage and probably cheaper to maintain both will be supremely cheap to run on that mileage, check the insurance side of things on a few first. The quotes I have done EVs cost a fair bit more, enough to make up the difference of using petrol on that mileage, though I was looking at far more performance orientated cars where the powers of EV and ICE don't align ~400hp ICE vs ~600hp EV , maybe similarly powered city cars are different.

Yes you can, just need the right setup, new powerwall etc will dump out 11kw continuous as will a couple of others now, though perhaps you have even more powerful show, mine is not too hard core at 9.5.

Yep exactly my point.
Car great, apart from when its not there.
So like for many people when they are at work, or doing the clubs/afterschool stuff etc
So what happens is the house battery can provide x kw. Where x is a combination of what the batteries can deliver and what the inverter can deliver. Obviously its the lower of the two.
My batteries can in theory deliver 12kw, but my inverter is limited to 5.5kw so I can get upto 5.5kw from the inverter only.
If I tried to pull 10kw then the batteries would be delivering 5.5kw and the grid 4.5kw
Plus many people think off grid storage for water is going to return. IE a hot water tank, or a hot sand box (or maybe other techs such as the chemical ones which also exist) to deliver hot water when needed, thats heated when off peak is cheap/negative, or export is very low priced. Etc.
I have used hardly any gas to heat my water for weeks. Between free hours and power ups on Octopus they happen regularly enough that the tank is always at least hot. When one of those sessions happens its VERY hot.

When you are not there the house draw is minimal, so do you really care the battery has gone for a jolly with you? Perhaps different if you have heat pump and want to use cheaper off peak electric but you will likely have a house battery in this case.

It’ll no doubt be expensive as myEnergi products usually are. The Zappi looking like a toilet seat put me off buying it.And most people have to have a car. Why not buy a V2G car, use that and when you move house, your battery moves with you. It seems so much more useful that a static battery system. Also, every time you change cars, you get an updated battery and V2G system. Roll on myenergis' new V2G EVSE:
Power to the people: myenergi starts work on new V2G EV charger | myenergi GB
British smart home energy technology manufacturer, myenergi has started development on what it believes is likely to be the UK’s first mass-marketwww.myenergi.com
I like how they use a Tesla as the stock image which does’t support V2G and who’s CEO explicitly talked down V2G on many occasions.
They only added it to the Cybertruck because of the success of Ford’s Super Bowl advert when people went nuts over it.

Imagine you live in a house when not everyone goes out together at exactly the same time, or on the same days...
Imagine when I drive to the allotment for a couple of hours and the other half decides to do some baking, or start the sunday dinner.
I suppose its easy for singletons

No one is talking about living in the Rockies are they? They are still on grid. Decent cooking session exceeding 3.6kW soon gets frustrating at the scoping phase of inverter sizing etc when trying to do a budget build in my view.
Exactly, I often think I'm living in a parallel universe when it comes to electricity usage. My efforts to reduce our consumption began and ended at swapping the light bulbs for LEDs. Our house is occupied 90% of the time Mon - Friday and yet our electricity bill is about £55 a month, £12 of which is the standing charge!
The idea of bolting a five figure sum of kit to my house with a pay off of the best part of a decade seems crazy to me but maybe that is in part because I don't see myself, at this point in my life at least, deciding that there is no chance I wouldn't move at the drop of a hat if my circumstances changed.
In comparison, if we are talking battery storage in a car I'd own anyway and all I had to do was pick a suitable tariff and configure a few things... absolutely I'd be on it.

You have got 3x V2G/H enabled cars sitting at home right now actually powering your home?
You what? The size of the inverter makes little difference to the cost in domestic installs now.
Most people in the rockies probably wont be going V2G/H any time soon.

This whole forum is people who overclock, tweak computers and spend thousands for marginally gains. Hardly a reflection of the normal use and certainly seems to carry over to OTT solar/battery builds that are being discussed here as a way to ‘save money’?
Why. Electricity is peanuts.

I've only been able to use my V2H solution for a week when I borrowed an Ioniq 5, but hopefully we'll have a 6 on the drive before the year is out and we'll have V2H and house battery. My setup is somewhat specialist as it uses the second AC input on my Victron Quattro to put the loads on to the car, and required setting up a special earthing arrangement. I don't expect it to be a permanent solution, it was just something I wanted to try as I was swapping out my inverter etc. any how. It will need a bit tweaking once we have the 6, as it will need to auto detect and fail over to AC2 input rather than the current manual switch over, and isolator.
Once that is complete I doubt I'll ever use a non-off-peak or solar generation unit of electricity, and fully expect to take advantage of export windows where possible as well.

Your a pretty low user then considering that. The average bill is £600 excluding SC.
For a five figure sum at todays pricing your talking a significant system. Put this way, my system which is that sort of amount generated me negative electricity bills from April-Aug.
Plenty of others are the same, and I am a very high user of electricity, 20kwh a day on average.
Most of the expensive parts of a solar system if you go for a solar and battery installation are easy to take anyway.
Most you can simply flip the breaker, and remove the inverter and batteries etc. You wouldn't bother with the panels as they are better every 12 months than before.
Mine would be fractionally harder as my incoming tails are diverted in order to provide whole house EPS in case of a power cut. So I would need a spark to take the old tails back out of my solar system and connect them back to the main house.
We had a power cut a few weeks ago, you would have thought the world had come to an end on the local facebook group complaining.
We were happily carrying on as normal, lights on, I was on the PC on the internet, she was watching TV, no drama.
For me it wasn't simply about the financials but also doing my bit to reduce my carbon footprint a bit. Everyone will be different.
V2H/G is great, I don't think you will find anyone who "gets" solar/home batteries who disagrees. In fact I would bet you would find a significant chunk who would be first to sign up for it if there was a different tariff etc would be both.

Go on then, whats the price between 3.6 and >5kw and AC or DC looped? 5kWh batteries discharge around 3.2kW too.
Then you have conditioners for the shaded nature of an install, etc etc.
so u wot m8 back

Can you write that in understandable English please.
Have you been assimilated by jpaul this morning or something.
The bit about battery size and discharge at least makes some sense. Well no, but its clear you aren't up to speed.
I have 3.2kwh batteries, EACH can discharge at 3kw.
You can get a 9kwh battery that can only discharge at 3.6kw as well.
So you buy the combination that suits the usage case. If you have a large inverter you want batterie(s) that give you the output to use that capacity.
If you have say a small 3.68kw inverter then you may as well go for one that has lower discharge as they will tend to be cheaper.
Soldato
Indeed, so not as simple as just the inverter sizing i think you have just agreed. The DC or AC determines if you can operate in a power cut...
Pretty straightforward terms.
Price for 3.6kW and price for 5kW was the original question if that helps?
