Solakon or Anker? Balcony Power Plant Battery Storage Comparison + Alternative 2026

In a nutshell: Solakon and Anker Solix are two popular providers of balcony power plants and storage systems. Both rely on modular systems, app control, and zero-export. Which one is a better fit depends on price, size, and ecosystem – and with the SunEnergyXT 500 PRO or BK215 PLUS, there's a third, often cheaper and independent option.

Solakon or Anker – what matters?

Both providers pursue the same approach: store solar surplus, increase self-consumption, and achieve close to zero-export using a smart meter. In everyday use, four points are crucial: capacity & expandability, control quality, app/service, and price per kWh.

Where Solakon scores

• German provider with complete kits and local service.
• Storage solutions like the Solakon ONE, designed for easy commissioning.
• Good advice for beginners.

Where Anker Solix scores

• Large ecosystem (Smart Meter Gen 2, Smart Plugs) and modern app.
• Wide range of models from the Solarbank 2 Pro to the 5 kWh Solarbank 4 Pro.
• High brand awareness and availability.

The SunEnergyXT alternative

If Solakon and Anker are too expensive or too tied to their respective ecosystems for you, it's worth looking at SunEnergyXT:

• 500 PRO (5 kWh, €1,349): "VERY GOOD" in the ComputerBild test, in the BILD practical test with quieter zero-export and earlier PV start.
• BK215 PLUS (starting from €698): modular up to 8.6 kWh – the affordable entry.
• Open: Zero-export with Shelly Pro 3EM, local Home Assistant API – no ecosystem lock-in.
• Immediately available.
