Overview
- A user test of Kleines Kraftwerk’s 2000 W Quattro set with the Anker Solarbank 3 reported about 280 kWh generated in the first month and estimated savings of €30–€60 per month, with simple self-installation aside from the smart meter.
- The Anker Solarbank 3 E2700 Pro offers 2.68 kWh usable capacity, up to 3,600 W input across four MPPTs, IP65 weatherproofing, LiFePO4 cells rated for about 6,000 cycles, and expansion up to 16.12 kWh.
- Market comparison shows 1,000 W duo sets priced roughly €249–€339 without storage, while bundles with batteries typically range from about €799 to €1,169, with solago praised for value and Solakon leading on entry price.
- Black Month promotions include Kleines Kraftwerk’s 2000 W bundle at €1,235 in one review and a separate 1,800 W package at €1,199, both pairing modules with the Anker Solarbank 3 and app-based control.
- Energy-storage expert Janik Nolden says batteries significantly raise autonomy and self-consumption, and the reports note the battery itself is not registered, though the balkonkraftwerk must be entered in the Marktstammdatenregister and a certified electrician should fit the smart meter.
