When the home battery is full and there is no immediate energy demand in the house, the electricity can be used or stored in several ways.

Firstly, the electricity can be used to power household appliances. For example, if you turn on your washing machine, dishwasher, or other devices at that moment, the electricity will be directly used to operate these appliances.

If there is no immediate energy demand in the house at that moment, the electricity can be redirected to the home battery. The home battery acts as a storage medium where excess energy can be stored for later use. The energy is stored as chemical energy in the battery cells and can be discharged later when there is an energy demand and the solar panels do not provide sufficient energy.

Additionally, it is also possible to supply excess energy back to the electricity grid. If you have a feed-in agreement with your energy provider, the energy you do not use yourself can be injected into the electricity grid. In this way, you contribute to the overall energy supply and the energy can be used by others.

The specific behavior of the home battery can vary depending on the brand, model, and configuration of the battery. It is advisable to consult the manufacturer's instructions for your home battery to gain a better understanding of how the power is managed when the battery is full.
