Overview
- Retailer Kleines Kraftwerk is promoting Anker’s SOLIX Solarbank 3 E2700 Pro for €999 with a free Smart Meter and free shipping, undercutting the listed price by €200.
- Anker’s unit offers 2.688 kWh base capacity with LFP cells, up to 3,600 W DC PV input for as many as eight modules, an integrated inverter set to 800 W and adjustable to 1,200 W, off‑grid output up to 1,200 W, and expansion to 16 kWh.
- EcoFlow’s new Stream Ultra X launches with 3.84 kWh capacity, accepts up to 2,000 W of PV across four inputs, provides two outlets up to 2,300 W, and is modular up to 23 kWh, with a launch price of €1,299 and a stated list price of €1,499 after September 16, 2025.
- Because balcony PV feed‑in to the home network is capped at 800 W in Germany, surplus generation is increasingly stored for evening and night use rather than curtailed or exported without compensation.
- Home&smart’s analysis notes typical additional savings of about €100–€120 per year from adding a battery with many systems paying back in roughly five years, while highlighting modular options such as Solakon ONE (2.11 kWh per master unit, expandable to 12.66 kWh, IP65/IP68) and growing smart‑meter and AI optimization features.
