In a nutshell: Anker Solix offers two very different league products with the Solarbank 3 Pro (mid-range balcony/home battery) and the Solix X1 (three-phase home battery system). We show prices, technical data, and who they are suitable for – and where the SunEnergyXT 500 PRO is the more affordable, independently tested alternative.
Key points at a glance
- Solarbank 3 Pro (E2700): approx. 2.7 kWh, modular – mid-range (from approx. €845).
- Solix X1: three-phase home battery system from 5 kW/5 kWh – premium (from approx. €3,349).
- Alternative: SunEnergyXT 500 PRO (5 kWh, €1,349, "VERY GOOD" according to ComputerBild) – expandable to ~270 kWh with three-phase power, immediately available.

View SunEnergyXT 500 PRO →Important: Operation with more than 800 W
5 kWh systems deliver more than 800 W and do not fall under the simplified 800 W balcony power plant rule. Export can be limited by zero export; otherwise, the obligations of a larger PV system apply – see MaStR instructions.
