Overview
- Retailers started heavy summer promotions in mid‑August 2026 offering 2,000 Wp plug‑in PV kits bundled with Anker SOLIX storage at about €1,300 to €1,829.
- Typical bundles pair four 500 Wp bifacial modules (2,000 Wp) with Anker SOLIX units: SOLIX 3 starts at roughly 2.7 kWh expandable toward ~16 kWh and SOLIX 4 starts near 5 kWh expandable toward ~30 kWh.
- Technical limits remain important because standard plug‑in inverters are set to feed about 800 W into the grid even if modules total 2,000 Wp, while professional installation can allow higher operating modes.
- Adding SOLIX batteries increases self‑consumption by storing midday surplus for evening use and offers backup sockets, but advertised yearly savings depend heavily on household usage, location, and tariff structure.
- Practical barriers persist: systems must be registered in the Marktstammdatenregister, some landlords or local offices can delay or block installs as shown by a Berlin tenant’s roughly year‑long dispute that only ended after intervention.
