Overview
- In mid‑June 2026 Anker began selling the SOLIX Solarbank 4 Pro, a 5.0 kWh usable LiFePO4 home battery that is modular up to about 30 kWh and is being offered in retailer Quattro/Quattro XL bundles with four 500 W bifacial TOPCon modules for roughly €1,793–€1,999.
- Anker’s product specs include four independent MPPT inputs with up to 5,000 W PV input, a 2,500 W continuous off‑grid/notstrom output, automatic switch to backup in under 20 milliseconds, a claimed 10,000 charge cycles and a 10‑year warranty.
- Retailers are sweetening launch packs by including Smart Meter Gen 2 hardware for real‑time three‑phase measurement plus cables and free shipping, and they advertise AI energy‑management that optimizes charging, discharging and dynamic tariff use.
- Early user reports and tests of SOLIX 3 systems show meaningful first‑month generation and modest monthly savings but real household benefit will depend on location, consumption profile, module orientation, Germany’s 800 W feed‑in limit and whether buyers attach loads to the dedicated backup output.
- Analysts say the current low bundle prices follow a familiar pattern of new storage launches being pushed with promotions and that long‑term durability and real‑world ROI remain to be validated beyond early tests and manufacturer claims.
