V2L function to power the house?

[johnb80]

Definitely not bi-directional at that price

You mention it is being installed next week - assume you have a sparky to do that for you as you've bought it via Amazon. Assume also you are aware of the DNO requirements for either approval vs. install and notify depending on supply adequacy / MD of 60A or less etc.

Yes, good point, well raised.

I've just installed one of the new Zappi Glo's for my son and his newly aquired Tesla Model 3. The installation was a breeze, the forms from the DNO not too onerous and as we knew the main fuse size, earthing arrangement and the Zappi was approved we only had to inform them not get permission.

If you have the option, cancel / return that wallbox. Units like this and many others are not recognised by the top EV tariff providers and therefore you wouldn't be able to use them. Intelligent Octopus GO is currently one of the cheapest at 3.49p off peak for 6 hours as well as other charging sessions during peak hours under their control. You can make good use of this by charging house batteries at the same time if IOG has given you extra sessions. You do need to use one of these:-
Ohme (ePod & Home Pro)
MyEnergi Zappi
Wallbox (Pulsar Max/Plus)
Hypervolt Home 3 Pro
Easee One

My favoured one is the Zappi, it's the most widely accepted wallbox amongst energy suppliers. It also integrates really well with Solar and energy diverters etc.

I m already on dumb octopus go which is only a penny more expensive (after vat).

Looked at it and I would only gain in winter and 800 quid more til payback at that rate. Only 5 hours on the dumb version but it will fill car and battery in that time and expansion of the battery to 20 kWh makes better economic sense to us. (Which would still fill in that time gap)

Current bill (pre electric car bought last week) is about £1.30 a day (including standing charge) as an average. (Ok it got loads of sun in that time) (5 bed bungalow)

I couldn't get my head round the intelligent go where they decide when you charge the car (during the day) and that was generally mornings, whereas if I need leccy it's late evening. Looked at the new solar plug in as well but it's hardly worth it to us as already have 4.2 kW on the FIT (2011) payments.

We are also out of the country for 2 lots of 3 months per year in motorhome (with solar and lithium) charging e bikes daily and never pay to top up electricity (or water, or campsites).

Thanks for the interest.

A fellow Motorhomer, with solar and lithium batteries, clearly set up to free camp as we are .... congratulations on the forward thinking .... now to convert the motorhome to EV so you can afford to travel
That is our next step, eventually having enough solar to recharge the EV battery as well, but that one is much further down the track, so it will be range extended type hybrid first off

I ve been putting some thought into ev motorhomes, as planning to keep this one for 5-6 years then blow the budget on ev motorhome, but only having bought this mg4 on Sunday it looks limiting for ev motorhome.

I can leave house with full (say 100 KW of battery) travel 200 miles (say) then fill up (presume 100 KW) in 2 hours for 60 quid. Pre Iran war that's slightly more expensive to my diesel in cost. (Especially Spanish prices)

Currently have 500 watts of solar and 300 ah lithium (LPG gas low) which (if I use the battery enough) will give me 1.5 KW on a good day or 4-5 miles of motorhome travel.

So I think the ICE motorhomes are around for a while as little saving in cost per mile for the way we travel. Using motorhome locally would be more beneficial, and I m assuming the cost of an EV motorhome would be higher than ICE.
If I downsize to a pvc in older age, I can see it occurring though, but not for a while, here's hoping and happy travelling

Our 30ft Winnie, towing the MG4 on a trailer, comes in at 12.5 tonne. The V10 6.8ltr 20 valve Ford engine goes great, but it is a tad thirsty, 2km/ltr thirsty.
200ltr petrol is good for between 400kms and 500kms, depends on hills, wind direction and the weight of my right foot ..... there is a certain amount of enjoyment pulling up past a B double in the short overtaking lanes they have around here. The price for that much fun was $400 for 200ltrs of petrol (the cheap stuff) that went up to $600, starts to hurt when the trip is 1600kms each way as the crow flies, so it wouldn't take all that long to recover the cost of 700kwh of battery storage.
Already have the hybrid set up, a Lexus GS 450h, a petrol V6 that develops around 300hp and the L112 2sp 2 motor transmission can develop over 270hp and incredible torque using the inverter board developed by Damien Maguire .... all fed into the near unbreakable Ford 4 sp heavy vehicle auto, I'm hoping this will be the motorhome till the end of my days travelling ....
Solar is good and cheap over this side, so fuel sort of comes down from the sky ....

700kwh of battery storage.

Jeez. That's a farm !

 

[T1 Terry]

Jeez. That's a farm !

That is the battery capacity of the Windrose EV prime mover that is claimed to be able to travel 680kms with 60 49 tonne total vehicle weight ....
So, using MG's method of distance capabilities on a single charge to real world possible achievement ratio of 75% on a good day and 50% on a not so good day, I might be able to get 1,000kms on a charge, 3 days good solar with all 5kw of solar deployed, and we should be good for another 1,000kms.
Cut it back to 350kwh, 500kms and 1 1/2 days recovery, more than suitable for a Grey Nomad ...., It would be 2 days anyway, getting all that solar deployed, only to pack it up a day later ..... yeah nah ....

Those giant battery trucks make financial sense if you are saving a huge amount of diesel.

If you've got an expensive truck you need to use it heavily to make the economics work.

For a leisure vehicle it is hard to imagine intensive working.

Perhaps the best scenario would be to have leisure vehicles available for hire so they could be used more intensively. But then probably everyone would want them at the same time! Perhaps families could use them in the school holidays and retired people and those without kids could use them the rest of the time. Is there a business case here?

In this case, it is our home at the moment and probably for the next 2 yrs until a replacement house is built. We will still want to travel, it wouldn't be to make money, it would be so we could still afford to travel ....

Just trying to imagine future business models etc.

For now we've got these motors - might as well make use of them if there is no obvious alternative. Better to electrify the priority areas first, like cars and heating and do other things as and when it makes sense.

Interesting with electric motorhomes that the high-voltage battery would be used to power the lower-voltage equipment. I guess it would effectively do so indirectly through a 12v or 48v system, just as happens with cars.
