Overview
- Anker launched the SOLIX 4 with about 5.0 kWh of LiFePO4 storage, a 2.5 kW inverter and support for up to roughly 5,000 W of solar input, shifting mini‑PV gear closer to the capacity of small rooftop systems.
- Multiple German retailers are selling steeply discounted 2 kW plug‑and‑play bundles that pair the SOLIX 3 or SOLIX 4 with four 500 W modules, making entry-level systems available for around €900–€1,800.
- Analysts and tests show the SOLIX 4's capacity is best exploited with larger PV arrays—home&smart’s analysis finds a 4 kW array roughly doubles annual yield and shortens payback versus a 2 kW setup.
- The SOLIX 4 adds new capabilities—an internal 2,500 W socket that can run heavy appliances or an EV charger and a 'Plugin Power' house‑coupled mode—but using full inverter output requires electrician installation and official registration.
- Beyond product specs, buyers should note regulatory and cost trade‑offs: Germany limits simple plug‑in feed‑in to ~800 W, module prices may rise after China’s April 2026 export changes, and realistic payback depends on sizing, installation and local solar yield.
