In short: Zendure SolarFlow and Anker Solix are two of the most popular modular balcony power station storage systems. Both are AC/DC-coupled, app-controlled, and suitable for zero export via smart meter. The choice depends on details, price, and ecosystem – and with the SunEnergyXT BK215 PLUS or 500 PRO, there's a third, often more affordable option you should know about.
Key points at a glance
- Zendure SolarFlow: very modular, compact, good charge/discharge management.
- Anker Solix: large ecosystem, modern app, many model sizes.
- SunEnergyXT Alternative: BK215 PLUS (2.15 kWh, modular up to 8.6 kWh, from €698) for beginners; 500 PRO (5 kWh) for more power – both immediately available.
Zendure SolarFlow or Anker Solix – what matters?
Anyone looking for a balcony power station storage system in 2026 will almost inevitably compare Zendure and Anker. Both pursue the same approach: storing existing solar power, increasing self-consumption, and achieving zero export as closely as possible via a smart meter. Four points are crucial in everyday use: capacity & expandability, regulation quality of zero export, app/software, and price per kWh.

If Zendure and Anker are too expensive for you or too tied to their respective ecosystems, it's worth taking a look at SunEnergyXT:
- BK215 PLUS (2.15 kWh, from €698): modularly expandable up to 8.6 kWh – the direct competitor to Anker Solarbank 2/3 Pro and Zendure SolarFlow, immediately available.
- 500 PRO (5 kWh, €1,349): if you want to start bigger right away – rated "VERY GOOD" in the ComputerBild test and in the BILD practical test with calmer zero export.
- Open & independent: Zero export e.g. with the Shelly Pro 3EM – you are not tied to a single manufacturer's ecosystem.

View BK215 PLUS →Important for more than 800 W
Larger expansion stages deliver more than 800 W feed-in power and therefore no longer fall under the simplified 800 W balcony power station regulation. The feed-in can be limited via zero export; otherwise, the obligations of a larger PV system apply. Our MaStR guide explains registration.
