Connect hot water heat pump with photovoltaic system

Hello everyone,

I am considering connecting our future photovoltaic system with a hot water heat pump in the basement and also operating it with photovoltaic electricity. Both are to be used in a new building.
Now the question: what interfaces must the heat pump have and what else do I need in terms of additional devices?

Thanks in advance.

Do not understand the question. All power lines meet at the fuse box or meter cabinet. When the photovoltaic system produces electricity, it is used in the household. So the heat pump is also operated with it.

Basically, your heat pump draws electricity from the photovoltaic system when it generates electricity. Therefore, the heat pump must not be connected to a separate meter but included in the household electricity. Optionally, the photovoltaic system with its components and the heat pump can be coupled together with an appropriate module.

I don’t understand the question. All power lines meet at the fuse box or meter cabinet. When the photovoltaic system produces electricity, it is used in the household. So the heat pump is also powered by it.

That is clear. It’s more about the control of the heat pump. I would like to prioritize the heat pump ahead of all other consumers. If the heat pump is "Smart Grid" capable, I have the following three control options:

1. Connect directly to the inverter
2. A smart meter
3. Control via an energy management system

I will clarify the question a bit: what do I need to consider with the three solutions and how do they differ in terms of the level of control? Also feel free to provide a link if this has already been answered somewhere.

I would like to prioritize the heat pump over all other consumers.

I still don't understand. Should the heat pump get the "own" electricity, the refrigerator, etc. the purchased one? What's the difference? Or do you mean that the heat pump should run when electricity is being produced?

Yes, exactly. Own electricity before all other consumers. There is a reason why I have to do it this way, but that is not important for the task at hand.
