Overview
- Over the late‑September weekend major German retailers advertised deep discounts on complete balkonkraftwerk kits that include 500 W bifacial panels, an Anker SOLIX storage unit and a smart meter.
- Examples cited by publishers include Yuma’s 2,000 W set with four 500 W modules and an Anker SOLIX 3 Pro for about €1,269, Yuma’s 1,000 W set for about €1,229, and Solago’s 4,000 W bundle with SOLIX 3 for about €1,829.
- Anker’s product line supports a clear upgrade path: SOLIX 3 offers ~2.7 kWh nominal capacity and 1,200 W AC output with expansion to roughly 16 kWh, SOLIX 4 starts at ~5 kWh and can scale much higher, and the Power Dock links multiple units for 1‑ or 3‑phase house connection and EV charging.
- Publishers’ calculations show storage greatly raises self‑consumption and shortens payback—typical 2 kW + SOLIX 3 setups are estimated to save €300–€500 per year while 4 kW systems yield larger annual savings and faster amortisation.
- Buyers must weigh technical and regulatory limits that distinguish plug‑in kits from full PV installations—common practice limits inverter feed‑in to ~800 W and module totals around 2,000 Wp—and note that offers are time‑limited and stock can change quickly.
