What is the function of a home battery?
Over the past ten years, many families have installed solar
panels. Until now everyone could use the reverse counters. If the production of the solar energy exceeds the consumption, this energy is put back into the grid and the counter turns back. If you do need the energy in the evening, you can get it back from the grid and the counter will turn forwards. However, the imbalance between the consumption and the production causes a considerable headache to the network operator/administrator because they have to take care of a constantly increasing heavier network. That is why the digital meter has been introduced. The backward rotating counters (and their advantages) will disappear: new installations can no longer benefit, and old installations will be granted a period of 15 years from the installation of the solar panels.Afterwards, the energy you put into the grid will be less profitable. It will then be important to make your own consumption (% ratio of the solar energy that you can immediately use yourself) as high as possible: by using smart consumers (smart washing machines, boilers,…) and/or by using home batteries.
An installation home batteries always measures the energy that goes to or from the grid. As soon as it notices that there is solar energy left, it will charge the battery. In the evening, when the sun no longer supplies that much energy, the battery will initially be discharged before it is switched to the more expensive grid power.
