sonnenBatterie 10 vs sonnenBatterie 10 hybrid
Technical comparison · All-in-one
Same 5 kWh of usable capacity, same declared cycles and the same 10-year warranty: on paper, the whole difference sits on the electrical side. The sonnenBatterie 10 is single-phase with no emergency power; the hybrid is three-phase and supplies the house in a blackout after a brief pause. All figures are manufacturer-declared.

The differences that matter
- Backup power, none vs three-phase EPS → in a blackout only the hybrid supplies the house.
- Phases, single-phase vs three-phase → the sonnenBatterie 10 works on one phase, the hybrid on all three.
- Continuous output, 3400 W vs 2500 W → the sonnenBatterie 10 carries more loads together; maximum charge follows the same ratio (3.4 kW vs 2.5 kW).
- Maximum expanded capacity, 20 kWh vs 25 kWh → the hybrid has more room to grow.
Which one to choose
Choose sonnenBatterie 10 if…
the house is single-phase and a blackout is not the priority: the aim is using in the evening what was stored during the day. It is 27 cm deep against 36. The trade-off is that during a grid outage the battery does not supply the house.
Choose sonnenBatterie 10 hybrid if…
the house is three-phase and you want it to stay supplied in a blackout: the switch happens after a brief pause (EPS) and covers all three phases. The trade-off is less discharge and charge power, and a 36 cm depth.
