Anker SOLIX Solarbank Max AC vs sonnenBatterie 10 performance
Technical comparison · All-in-one
Two home batteries for different houses: the Anker sits on a single-phase installation and keeps the house running in a blackout; the sonnenBatterie works on three-phase at twice the power but has no backup function. That is the choice to make before looking at anything else. Figures are manufacturer-declared.

The differences that matter
- Continuous output, 3500 W vs 7000 W → the sonnenBatterie feeds more appliances at once; the Anker hits its ceiling sooner in a house with many loads running.
- Backup: UPS in 10 ms vs none → only the Anker keeps the house on during a blackout.
- Single-phase vs three-phase → decided by the connection you already have at home.
- IP66 and -20 to 55 °C vs IP30 and -5 to 45 °C → the Anker can go in a garage or outdoors; the sonnenBatterie wants an indoor room.
Which one to choose
Choose Anker SOLIX Solarbank Max AC if…
you have a single-phase installation and want the house to stay powered when the grid drops: the Anker switches over in 10 ms, like a UPS. You accept 3500 W continuous, half of the other unit, and no three-phase connection. With IP66 and an operating range of -20 to 55 °C it can also stand outdoors, on the floor.
Choose sonnenBatterie 10 performance if…
your house is three-phase and you want a battery that carries several loads at once: 7000 W continuous, 7 kW charging, 10 kWh usable and up to 50 kWh with expansions. It talks to the wallbox and joins the sonnenVPP virtual power plant. You give up backup power: with the grid down, the house stays dark. With IP30 and -5 to 45 °C it belongs in an indoor room; it is 172 cm tall and weighs 165 kg.
