Overview
- New bundle offers include a 2,000 W set with Anker Solarbank 3 for €1,299 at Kleines Kraftwerk and a PiE POWER 2,000 W + SOLIX 3 package for €1,439 at PluginEnergy, while Solakon’s 2,000 W XXL set with a 2.11 kWh battery is €989.99 and its onLite kit starts at €209 without storage or €839.99 with storage.
- Deal roundups report effective storage pricing down to about €205 per kWh for systems such as Growatt’s NOAH 2000, underscoring sharp declines in battery costs.
- Anker’s Solarbank 3 E2700 Pro features a 2.68 kWh base capacity expandable to 16.12 kWh, four MPPT inputs up to 3,600 W, a 1,200 W backup outlet and LiFePO4 cells rated for about 6,000 cycles, earning strong test scores and positive user feedback.
- A one‑year user review of the Solarbank 2 Pro logged a 39% self‑sufficiency rate and roughly €215 in annual savings from the battery component, with measured losses of about 16% PV‑to‑house and 25–30% round‑trip through storage.
- Another test of a 1.96 kWp setup with a 3.2 kWh battery produced 1,156.77 kWh in a year and €267.87 in direct savings, with estimated payback at about 3.5 years without storage and a little over eight years with storage.
