Solar pV, Tesla Powerbank and Kia e-Niro integration ??

[ChrisW.]

I'm aware that a Tesla car can be integrated as a potential Powerbank extension.

However, our car charger is a Siemens charger from an earlier BMW i3 purchase in 2014 now working perfectly with our e-Niro ... can this and the e-Niro be integrated into our Solar pV and Tesla Powerbank system ?

I think that Myenergy Eddi is possibly something that could help.

Does Tesla do V2G now?

I believe Cybertruck may do something. Might be V2L though, and needs Powerwall (3?) integration.

Why not simply add a solar battery?

The simple answer here is of course you would have to buy that additional battery whereas using the one in the vehicle has no additional cost (nor the environmental issues of creating a new battery when you already have a 'spare' sitting there)

It is alleged that some Tesla vehicles have an inverter/charger so could theoretically push AC back to the house/grid.
In my view, that is an odd way to do it... you don't really want the inverter part built in to all vehicles, it would seem better to connect via DC and have both the charger and inverter fixed at home (though that is a technical point).

But, to answer the OP, I don't think there is a sensible, off the shelf way of doing what he wants at the moment.

Most vehicle batteries are Li-ion chemsitries which have a finite cycle life.
Most home batteries are LifePO4 which have a much greater cycle life.
Some Tesla cars are LiFePO4. Not all, not many?
Off grid LifePO4 batteries can be quite cheap to buy.

When you include capital cost and the cost of messing about, the savings to be had from using your car to power your home look very slim to non-existant.

There are many variations on integrating solar, batteries and EVs, easy to talk at cross purposes.
One interesting one is fast charging an EV from a home battery which can be charged by solar or cheap grid electricity.

The big picture is that the market has changed quickly in a few years and will keep changing IMHO.
So any cunning wheeze to save money needs to pay back very fast.
