A home battery stores electricity for use after sunset, during expensive tariff periods or when backup power is needed.
When a battery can make sense
- You export significant unused solar energy
- Your evening electricity use is high
- Time-of-use tariffs reward load shifting
- Backup power is important to your household
Size the system around real usage
The best capacity depends on consumption patterns, solar production, backup priorities and budget. An energy assessment is more reliable than choosing the largest available battery.
