Despite its liberalization in 2014, the Belgian electricity market still has some peculiarities. High market dominance of a few large energy companies, especially in the Brussels metropolitan area, comparatively low self-generated electricity, a high import rate especially in winter and regular blackouts do not make it easy for consumers to get fair energy prices. This makes the use of self-generated electricity in the kingdom very attractive not only for commercial actors, but also for private users.

The family from Brussels sought appropriate advice and installed a solar system with a peak output of 14 kWp in the garden. The plant generates electricity mainly during the day, i.e. at times when the family is usually not at home, but at work or at school. In order to use the electricity produced during the day, the family still needed an electricity storage system.

In addition, the family wanted to be protected in the event of a power outage and not only being able to continue using consumers in the house without restriction, but also to be able to continue operating sensi- tive computer applications. In addition, the family plans to acquire an electric vehicle that can be charged at night via the battery storage system when solar power can no longer be produced.

Requirements for a storage solution:

• Backup function in the case of a blackout 
• Expandable and powerful storage system that enables ev-charging
• Sustainable and long-lasting investment
