Running your house from your Electrical Vehicle Battery

Most EV's nowadays have got a direct high voltage DC connect for use with the fast chargers. 

What I find particularly interesting is that he is using the Inverters MPPT controller to convert the 330V DC into AC power for use in his house. 

I was thinking that I could use the Aux input on my Sunsynk and connect a grid-tie 3kw inverter to the DC Port on an EV and use that to supplement my Inverters battery.

mmmm..... now how does the cost of such an EV compare with the cost of getting some more Lithium batteries for the Home Solar?
When and how is the EV charged if the EV is used as battery storage?
I suppose if you have the money to spend on an EV then you probably have enough to invest in a self sufficient Home Solar system

This is definitely a future benefit of EV.

The above average Off-Grid users probably have 20-30 kWh in battery storage.

These above average EV's have at least double that:

  • Model 3 LR: 70 kWh
  • Model S Plaid: 90 kWh
  • Rivian R1S: 120 kWh
  • F1 Lightning ER: 155 kWh

I can definitely see a future where the vehicle is charged with Solar and the vehicles battery is used as a backup storage for those snowy days.
Probably not in South Africa, but the technology is there and shouldn't be too complicated to get going.
