Overview
- Late August coverage shows many German sellers marketing complete 2,000 Wp balcony PV bundles that include four ~500 W bifacial modules, an inverter or integrated inverter, cabling and a storage unit.
- Prices vary sharply across outlets with common deals around €1,200–€1,900 and a notable low‑price offer of €899.99 reported for Solakon’s onPower 2 kWp kit by PC‑WELT.
- Anker’s SOLIX family (SOLIX 3 ≈2.7 kWh, SOLIX 4 ≈5 kWh / Solarbank 4 Pro ≈5.0 kWh) appears in many bundles, making SOLIX the de facto storage choice in current comparator articles.
- German rules that limit AC feed‑in to about 800 W mean vendors oversize module capacity to raise daytime yield and rely on batteries to store excess energy or on the inverter to curtail output.
- Reviewers advise buyers to match PV and battery size—SOLIX 4 often performs best with roughly 4 kWp of panels—register systems in the Marktstammdatenregister and ensure required residual‑current and overcurrent protection for safe, compliant use.
