ᐅ Switchable high-voltage power outlet

Hello

We will soon get an e-Golf that we want to charge using our two photovoltaic systems. One has been installed since 2011 and the other one this year. Since one is on the east side and the other on the west side, we want to make full use of the morning sun and the midday/afternoon sun.

For this, we have installed two high-voltage power connections. However, we currently have to manually switch around 12 noon to use the corresponding photovoltaic system.

Is there a solution for this? A manual transfer switch where both power connections are routed and that can be switched by hand? Or perhaps even a solution that can be controlled via LAN cable or Wi-Fi? Ideally, a socket outlet with an integrated timer that automatically switches at a set time to the "other" photovoltaic system...

What is this called? Does anyone know of anything similar?

Two contactors and a current sensor with hysteresis. It automatically switches back and forth depending on which system is currently supplying power.

So, the photovoltaic electricity is not available for use within the household? That would be the most obvious option. Does it feed in 100% or how do you operate the systems?

But both systems supply power all day long. Even when the sun isn’t shining directly on the system, it still provides some (albeit much smaller) amount of electricity. So that’s probably not an option?!

Actually, it does. The electricity is consumed, and what’s left over is fed into the grid. But that’s not really the point in the end. I just need to somehow get most of the electricity currently generated by the photovoltaic systems into the car. And that is in the morning from the east and in the afternoon from the west.

Sorry, but I don’t understand this.
Both photovoltaic systems are available to the household.
This means that if you plug your car into a socket, it will be charged with the photovoltaic electricity instead of power from the grid, as long as the photovoltaic system is supplying electricity.
I also don’t understand what you want to do with two sockets, especially since I understand that one socket would be for photovoltaic system 1 and the other for photovoltaic system 2. But that doesn’t make sense if both systems are connected to the house network.

Or is your aim to keep the car permanently plugged into the socket and only start the charging process when the photovoltaic system (whichever one) is generating electricity?

Please arrange for a trusted electrician to come to your house. From your description, it is not entirely clear what the current situation is and what changes need to be made.
