Overview
- Retailers ran heavy summer promotions that pair 2,000 W module kits with the Anker SOLIX 3 E2700 Pro at prices around €1,200–€1,307, effectively making the panels a low‑cost add‑on to the tested storage unit.
- The SOLIX 3 remains a category leader with 2.7 kWh base capacity, AC bidirectional charging, Anker Intelligence AI for tariff and weather optimization, and backward compatibility with SOLIX 2 battery packs.
- Manufacturers and specialist sellers are also pushing larger mid‑size offers using Anker Solarbank 4 Pro or SOLIX 4 with about 5 kWh storage and higher PV input to serve households with greater daily loads.
- Regulatory changes to VDE-AR-N 4105 introduced simplified procedures for certain systems up to 7,000 W in March 2026, which has enabled vendors to market mid‑size complete sets that sit between plug‑in balkonkraftwerke and full rooftop PV.
- Adding battery storage sharply raises self‑consumption (typical shares cited rise from about 50% to 80%+), which vendors say shortens payback to roughly 2–9 years depending on location, household use and system size.
