Overview

  • Retailers roll out aggressive deals on storage sets, including Powerness’ Anker Solix Solarbank 2 Pro package with four 440‑watt modules from 879 euros on pickup (1,059 euros delivered with code “Anker250off”), featuring a 1.6 kWh unit expandable to 9.6 kWh with backup capability.
  • Anker’s newer Solarbank 3 E2700 Pro is marketed by Solarmars at 1,319 euros for a 2,000‑watt set with code “FKSM50” and 1,599 euros for the 5.4 kWh bank‑plus‑expansion, with reported payback estimates of roughly 2.9 to 3.6 years based on retailer calculations.
  • Solakon opens preorders for the ONE all‑in‑one storage ahead of a September 7 sale, offering 2.11 kWh per unit stackable to six, IP65 weather protection and a 1,200‑watt backup outlet, priced at 749 euros for the master and 599 euros per expansion battery.
  • APSystems’ EZHI system paired with Hailei storage is promoted by Talent International with claims of up to 12 kWh daily generation from four 440‑watt panels, off‑grid output up to 1,200 watts and expandable storage to at least 40 kWh, with a 1,520‑euro set and a 1,199‑euro storage‑only option; these are vendor‑stated figures.
  • Market reporting highlights battery costs near 300 euros per kWh and modular or virtual coupling beyond 30 kWh, while Maxxisun’s Maxxicharge V2 appears with 3.072 kWh at 1,449 euros or 5.222 kWh at 1,949 euros, UPS and LAN additions, and scalability the company says can extend to multiple units.
