Anker's SOLIX Solarbank 3 Pro Launches, Redefining Germany's Balcony Solar Market

The advanced storage system offers 2.68 kWh capacity, AI optimization, and emergency power, but state subsidies for mini-PV batteries remain absent.

Viele fragen sich, ob sie ihr Balkonkraftwerk mit oder ohne Batteriespeicher betreiben sollten.

Overview

  • The Anker SOLIX Solarbank 3 Pro, launched in Germany, features 2.68 kWh storage capacity, expandability up to 16 kWh, and AI-driven energy management.
  • Priced at €1,299 with additional modules costing €700 each, the system includes a built-in 800 W inverter and emergency power functionality.
  • Analyses show that adding a battery to 600–800 W balcony PV systems can yield over €100 annually in self-consumption savings, far exceeding the €30 typical feed-in revenue.
  • Experts recommend storage capacities of 1.6–2.0 kWh for 800 W systems, with battery lifespans estimated at 5,000–7,000 cycles or 15–16 years.
  • Despite the rapid adoption of decentralized solar solutions, no dedicated state funding exists for battery storage in balcony PV setups, unlike larger solar installations.
