Overview
- Retailers in early June 2026 are selling 2,000 W balkonkraftwerk bundles that include four high‑power bifacial panels plus the Anker SOLIX Solarbank 3 Pro for roughly €1,200–€1,400.
- The SOLIX Solarbank 3 E2700 Pro in these deals is a ~2.68 kWh LiFePO4 all‑in‑one unit with an integrated inverter, four MPPT trackers and plug‑in expandability to about 16 kWh.
- Sellers stress included Smart Meters and AI energy management to obey German rules that limit direct feed‑in to roughly 800 W and to shift excess generation into the battery for evening use.
- Independent user tests show short‑term, real‑world savings vary a lot: a CHIP.de May 2026 household trial of a similar 2,000 W setup with ~2 kWh storage saved about €46 in one month and reached 43% self‑consumption, which is well below some headline annual estimates.
- The deals reflect faster panel tech and Asia supply pressure that drive prices down, but outcomes will depend on available mounting space, household use patterns, seasonality and proper registration with the Marketstammdatenregister.
