Overview
- Retailers and specialist vendors launched steep mid‑June sales that bundle 1–5 kWh Anker SOLIX storage units with 1–4 kWp module packs, cutting prices on complete Balkonkraftwerk+battery kits to roughly €1,300–€1,800 in several advertised deals.
- Anker’s SOLIX family now features integrated inverters, smart‑meter compatibility, modular add‑on batteries and a Notstrom (islanding) function that lets a storage‑equipped system supply limited emergency power when configured for island operation.
- Basic plug‑in mini‑PV without storage still shuts off in a blackout because safety inverters legally use grid voltage as a reference and include anti‑islanding protections that prevent backfeed to the grid.
- Notstrom performance and savings remain constrained by device output ratings and German operating rules: feed‑in limits (commonly ~800 W) and many storage units’ modest emergency outputs mean households can typically run routers, lights and small loads but not large appliances for long.
- For consumers the shift matters practically: modular storage raises evening self‑consumption and outage resilience, but real ROI and blackout benefits depend on system sizing, Notstrom output, smart‑meter setup and household use patterns.
