Several ways to move towards energy autonomy
Self-consumption is the principle according to which the user consumes all or part of the energy they produce. The objective is to move towards energy autonomy and a 100% self-production rate. Renewable energy sources (most often photovoltaic panels) are key when it comes to achieving this objective.
- On the fly: electricity is consumed directly at the time of production.
- With control: electricity is consumed according to photovoltaic production.
- With storage: the surplus of renewable energy produced is stored in batteries and consumed later.
Note: the self-consumption of a building can be individual or collective.
Combining the demand side of management and energy storage allows users to:
- guarantee a greater independence of energy from the grid
- reduce and control costs, in terms of the installation and energy consumption
- limit photovoltaic injection into the grid and conserve the existing infrastructure
- generate new sources of income by deriving value from the energy produced and stored

The SUNSYS HES storage system
The SUNSYS HES L storage system combines a bi-directional power converter and batteries to provide self-consumption with storage. SUNSYS HES L integrates a control system which manages self-consumption in order to maximise savings:
- by setting a consumption threshold from which it is preferable to use the energy from the batteries
- by making sure that the battery is available for charge (is sufficiently discharged) when the photovoltaic production is higher than the consumption
