Hello

we will soon receive an e-Golf that we want to charge with our two photovoltaic systems. One is from 2011 and the other from this year. Since one is on the east side and the other on the west side, we want to fully utilize the morning sun and the midday/afternoon sun.

For this, we have now installed 2 high-current power connections. However, we would have to manually switch around 12 noon in order to use the corresponding photovoltaic system.

Is there not a solution for this? A start current switch into which both power connections lead and which can be easily switched by hand? Or maybe even a solution that could be controlled via LAN cable/Wi-Fi? Ideally, a socket with an integrated timer switch that automatically switches to the "other" photovoltaic system at XX:XX o'clock...

What is this called? Does anyone know of something comparable?

Two circuit breakers and a current detection with hysteresis. It then switches automatically back and forth depending on which system is currently supplying the current.

That means the photovoltaic power is not available in the household now? That would be the most obvious. Does it feed in 100% or how do you operate the systems?

But both systems supply power - all day long. Even if the sun does not shine directly on the system, it still supplies (albeit a significantly smaller) amount of power. So that's probably not an option?!



Yes, it is. The power is consumed and whatever is left is fed in. But that's not really the point in the end. I just somehow have to get the majority of the power currently generated by photovoltaic into the car. And that is in the morning east and in the afternoon west.

Sorry, but I don't understand that. The two photovoltaic systems are available to the household. That means if you plug your car into a socket, it will be charged with photovoltaic power instead of power from the grid, provided that the photovoltaic system is generating power. I also don't know what you want with two sockets, especially since I understand it as one socket being for photovoltaic system 1 and the other for photovoltaic system 2. But that's nonsense if both systems are connected to the house network.

Or is it about leaving the car plugged into the socket all the time and only starting the charging process when the photovoltaic (whichever one) is generating power?

Please order a friendly electrician to your house. From your explanations, it is not really clear what the current situation is and what is to be changed now.
