 The coupling of a photovoltaic system with a storage unit, a heat pump and a wall box for electric vehicles may require a so-called "Energy Management System" (EMS) solution.

With an EMS, these different components can be efficiently connected and controlled to optimize the self-consumption of the generated solar power and to control the energy flows in the household.

Here is a basic description of how these components might be coupled:

  1. Photovoltaic system: The photovoltaic system converts sunlight into electricity. It is installed on the roof or in a suitable place to capture as much solar energy as possible.
  2. Storage: Storage is used to store excess solar power that is not immediately consumed in the home. The stored electricity can be used at a later time when the sun is not shining or the electricity demand is higher.
  3. Heat Pump: A heat pump uses electricity to harness environmental heat to heat or cool the home. By connecting to the EMS, the heat pump can be controlled in such a way that it runs preferentially when there is sufficient solar power and the heat pump can therefore be operated in an energy-efficient manner.
  4. Wallbox: The wallbox is a charging station for electric vehicles. The Wallbox can be controlled via the EMS in such a way that it is charged preferentially when sufficient solar power is available.
  5. Energy Management System (EMS): The EMS takes over the intelligent control and coordination of these components. It monitors the power consumption in the household, the solar power yield, and the state of charge of the storage tank. Based on this data, the EMS makes decisions about when and how much energy is stored in the storage system, delivered to the heat pump, or used to charge the electric vehicle.

The goal is to maximize self-consumption of solar power and minimize the use of expensive grid power. The exact implementation may vary depending on the manufacturer and model of the components. In some cases, manufacturers offer integrated solutions that seamlessly connect all components and can be operated from a central control device.
