3.1 Mode of Operation
The battery system optimises internal consumption, thus reducing the amount of electrical energy needed
from the public grid. Energy from a photovoltaic system that is not required in the home at that time is stored in a
battery and supplied to the consumer as necessary.
Consumers are supplied with their own energy by the device in a manner which is flexible and optimised to their
personal habits.
