Overview
- Multiple vendors and discounters are offering standardized Quattro packages made of four 500 Wp bifacial TopCon modules, an Anker SOLIX storage unit and a Smart Meter at steep, time‑limited prices around €1,200–€1,900.
- Offers commonly pair the well‑rated SOLIX 3 Pro (≈2.7 kWh base) or the newer SOLIX 4 (≈5 kWh start capacity) with modular expansion options that let households grow battery capacity over time.
- Under Germany’s Solarpaket 1 and updated VDE guidance these plug‑and‑play mini‑PV arrays use up to 2,000 Wp of modules while inverters typically limit grid feed to about 800 W, so sellers design kits to meet those rules.
- Retailers differ mainly on included extras and service such as the exact panel brand, mounting systems, shipping costs and whether premium halterungen or an expanded warranty are bundled.
- Adding a SOLIX battery captures midday surplus that would otherwise be lost, raises self‑consumption into evening hours and can cut household bills by a few hundred euros a year depending on location, usage and assumptions about yields.
