Smart interaction between photovoltaic system, battery storage and electric vehicle is playing an increasingly important role in optimising a building's own regenerative solar energy demand to counteract limited energy supply. A smart wallbox is used to charge the electric car from the building's own photovoltaic system or inexpensively from the energy grid via the smart, digital bi-directional meter. A grid isolation device enables the use of hybrid photovoltaic inverters and battery storage to continue supplying electricity during an energy grid outage. The training system makes it possible to set up and configure a practice-oriented residentiual hybrid photovoltaic system with battery storage and grid isolation device. It can be expanded to include a wallbox, digital bi-directional meter and smart home control system.
