sonnenBatterie 10 vs sonnenBatterie 10 performance
Technical comparison · All-in-one
sonnenBatterie 10 and sonnenBatterie 10 performance share LFP cells and a 10-year warranty; what changes is size and grid connection. The first is single-phase with 5 kWh usable, the second three-phase with 10 kWh usable and about twice the output (manufacturer-declared values).

The differences that matter
- Single-phase vs three-phase → the first check: it follows from how the house is connected, not from preference.
- 5 kWh vs 10 kWh usable, expandable to 20 vs 50 kWh → how much of the day's energy can be moved to the evening.
- 3400 W vs 7000 W continuous, charging at 3.4 kW vs 7 kW → how many loads run together and how quickly the battery fills.
- 98 kg and 27 cm deep vs 165 kg and 36 cm → the weight to handle and the wall or floor space needed.
Which one to choose
Choose sonnenBatterie 10 if…
your home is on a single phase and 5 kWh usable is enough, with room to grow to 20 kWh through additional modules. You accept 3400 W continuous and charge power, and a single phase. It is also the only one of the two that declares the CEI 0-21 standard.
Choose sonnenBatterie 10 performance if…
your home is three-phase or your consumption is high: 10 kWh usable, 7000 W continuous, 7 kW charging, growth up to 50 kWh and access to the sonnenVPP virtual power plant. You accept 165 kg against 98 and a depth of 36 cm instead of 27, which asks for more room in the utility space.
