Overview

• A broad discount wave spans Powerness, Kleines Kraftwerk, Solago, AC TEC and Solakon, with multiple storage-equipped 1–2 kWp kits priced under €1,000, including €849 for an Anker Solarbank 2 Pro Quattro set and €989.99 for a 2,000 W Solakon package with a 2.11 kWh battery.
• Powerness lists an EcoFlow Stream Ultra X bundle at €1,259 with 3.84 kWh storage, four 450 Wp bifacial panels, a free smart meter, 800 W grid feed and 1,200 W backup output, with free pickup options across seven German locations.
• Competing Anker SOLIX 3 packages include Solago’s four-by-500 W set for €1,379 and AC TEC’s 2,020 W option for €1,375, with an extra €100 discount via code ANKER100 and an included smart meter; mounts typically cost extra.
• Current offers emphasize all-in-one designs with integrated inverters, multiple MPPT inputs, LiFePO4 batteries, modular expansion up to roughly 12–16 kWh and zero-export control via bundled smart meters, plus 1,000–1,200 W emergency power functions.
• Vendors promote short payback claims of about three to four years, while independent checks cite eight to twelve years depending on usage, as simplified registration and the 800 W feed-in limit help push Germany past one million registered mini-PV systems.
