With an off peak tariff the battery makes sense. Our 3kwp PV system makes 2600kwh/year of which 1000 was exported, domestic use is 3800kwh/year. In winter there is virtually zero solar power, charging the battery off peak makes 90% of our usage off peak.
Off peak with Octopus Go price matches...
Octopus Go does not split domestic and EV use, it is worth installing a domestic battery, charge it off peak and pay most of your usage at the current price of 12p.
When charging the car the battery will output through max inverter capacity and the rest will come from the grid (3.6kw from inverter and 3.4kw from grid I think).
Make sure your battery is not feeding the EV during off peak hours when it should be charging.
To power the house during a powercut you need to cut off the grid before connecting V2L, either manually or through an automated circuit breaker.
If you don't and the power comes back while V2L is powering the house the random phase off sync will smoke your things.
My previous car was a 59 reg A3, I have bought a brand new MG5 and not even considered a brand new A3.

With a 10miles commute company car I would had been happy with as brand new A3.
Say you ditch the ZS because electricity is too dear, how do you feel about domestic use?
Install a domestic battery to cover your daily use and switch to Octopus Go, pay 7 times less. And buy the ZS, and charge it at the cheap off peak rate.
If Octopus goes bust the only way to protect your...
