Overview
- Multiple retailers are listing 2,000 W (4×500 W) module bundles with the Anker SOLIX 4 Pro (≈5 kWh) at about €1,759–€1,779, and SolarMars is offering a short‑term coupon (HSMD2000) that cuts the advertised price to €1,779.
- The SOLIX 4 Pro is reported to provide roughly 5 kWh usable LiFePO4 capacity, up to 5,000 W PV input, a 2,500 W emergency output, expandable to about 30 kWh, and an advertised 10,000 charge cycles.
- Retailer math for a 2,000 Wp + SOLIX 4 set estimates around 2,000 kWh of annual generation and implies a roughly three‑ to four‑year payback in many cases, though actual savings depend on household use and electricity prices.
- Cheaper alternatives aimed at typical balcony users include the SOLIX 3 Pro (≈2.7 kWh) at about €899 and discounter 2,000 W + smaller storage bundles priced near €1,289–€1,299, which analysts say suit most small households better than the larger SOLIX 4.
- Buyers are being reminded that German rules limit grid feed from plug‑in systems to about 800 W AC, and larger multi‑module sets (for example ~6,000 Wp) are treated as full PV installations that require registration and network notification though systems under 7 kWp can use a simplified VDE‑AR‑N 4105 procedure.
