Overview
- Retailers list record‑low Quattro bundles with storage, including Growatt NEXA 2000 sets from €889 at Powerness, €925 at ACTEC and €999 at Tepto, with local pickup options to avoid shipping fees.
- Powerness promotes additional markdowns on Growatt NOAH 2000, pricing the 2.048 kWh unit at €469 with code NOAH180off and offering complete sets from €699.
- Anker’s Power Dock, priced from €329 via Powerness, links up to four Solarbank 3 units and manages energy flows with wallbox support, enabling combined storage up to 64.5 kWh.
- Quattro and Duo sets spotlight backup power, app control and smart‑meter‑enabled zero feed‑in, with systems marketed for plug‑and‑play installation and expandability to 8 kWh or more.
- Anker Solarbank 2 and 3 deals coexist, with under‑€900 Anker Quattro sets via pickup and payback claims of roughly 2.5–4.5 years depending on price, yield and usage assumptions; Anker says a forthcoming update will add Power Dock compatibility for some older models.
