Here is a sharing of information about charging my used Smart Electric Drive.

The car charger regulates an average of 1.9kW on my home 16A outlet.
As a result, not producing enough to cover my needs at home + the car, total of about 2.3kW, the inverter would dip into the battery pack to make up the difference. The last thing I needed to recharge a battery was to dip into another battery pack :!:

So, on the inverter I have switched the parameter 01 to SOL during the charge (in an automated way).
As a result, the batteries of the inverter are not solicited anymore, the PV generates what it can, today about 2 kW.

This made a difference of 300 W on average to be taken from EDF.

On the load which lasted from 12h00 to 15h10, the car in load consumed 6.6 kWh to pass from 65 % to 100 %. Estimate to go from 65 km estimated to 143 km meter.
Knowing that 87 % were produced by my solar panels, the load cost me 6.6 kWh * 0.16 cts/kWh * 13 %, that is to say 14 cents for approximately 78 km potential.

If we transfer these values to the 100 km, it makes 18 cents. Or less than 1€ for 500 km
If I’m not mistaken in my figures, it’s really impressive.:sun:

And when the sun is higher in the sky again, the panels can provide 3.5 kW, so recharging will be totally free.
This is clearly a good thing.

Below the graph of the charge and the observed consumption:

and the energy consumed
