Wallbox inside or outside ?

[ftonellotto]

EVCC is good in the summer when you have a surplus of production beyond the consumption of the house.

In winter, however, it is convenient to keep the wallbox outside the house (connected directly to the grid but not to the photovoltaic) so as not to discharge the home battery storage.

I made a double relay that electrically moves the wallbox from inside the house to outside the house with a button.

Is it possible to have an option that allows EVCC to change the calculation of home consumption if the wallbox is outside or inside the house?

Is it possible to have an option to indicate the maximum power that can be delivered by the operator before being disconnected from the line due to overpower?

Many home batteries can be locked by evcc to prevent discharge when a fast charge is running or when a charge plan is active in PV mode.

ok for the maximum limit of my grid. Now it's ok.
For the battery lock however I am NOT in agreement.
In winter and at night I want to charge the car (in fast or in minpv) but NOT affecting the house battery which must however continue to be used only for the house's night-time consumption.
FROM what I understand, when the battery is locked it does not supply power to the wallbox or to the house??

that´s right.

as I unterstand, your grid meter knows the charge power during summer and does not during winter?
Then, you should define a custom grid meter, that adds (during winter) the charge power to the grid measurement.
Using a trigger for the status of the double relay, it will work automatically.

A question out of curiosity. What difference does it make to you? Power is power, it doesn't really matter... If you charge your car from the battery it's your PV energy, after the battery is empty you need to pay for grid for house consumption and remaining car charging.
But it's also the same the other way around, if you charge your car fully from the grid and use battery only for house consumption.

In the end you spent the same amount of money, as you imorotet/imported same amount from grid.

The house is private.
The car is owned by the company where I work and they reimburse me for the cost of charging the car.
I want the photovoltaic and home battery to be independent from the energy management of my home.
