Your solar energy — available 24/7
Paired with your photovoltaic system, a battery allows you to store surplus solar energy and use it in the evening, at night or on cloudy days — for maximum energy independence.
Three reasons to go battery
Greater autonomy
Use up to 80% of your solar production, even without sunlight. Drastically reduce your grid dependency.
Power outage protection
In case of grid failure, your installation stays operational. Lights, fridge and chargers keep running.
Smart management
Dedicated app to monitor production, consumption and charge level in real time. Automatic energy flow optimisation.
A project with no surprises
Consumption audit
Analysis of your consumption data to precisely size the required storage capacity.
