Introduction
Today, a domestic battery can do much more than store solar energy. Coupled with an intelligent system (EMS), it optimizes your consumption and can even generate income by helping to stabilize the Belgian grid.
01Why install a battery in 2025?
- Increase your self-consumption rate to 85%.
- Reduce your dependence on the public grid.
- Participate in the balancing market (remunerated) with Elia.
02.intelligent storage with EMS: how it works
- The EMS automatically decides when to store, consume or inject.
- It adapts to network signals to maximize your savings.
- It makes your battery more profitable, by putting it to work for the grid.
03.return on investment and case studies
- Battery life: 10 to 15 years.
- Average ROI: between 7 and 10 years, depending on battery size and region.
- For example, your battery recharges when the grid has a surplus, and injects when it needs to.
