Overview
- A six‑month practical test of EcoFlow balcony storage found typical coverage closer to about 42% for a 2 kWp setup, undercutting the company’s advertised “over 70%” figure.
- Measured efficiencies were strongly load‑dependent, at roughly 69–75% around 150–250 W and stabilizing near 80–83% from about 500–800 W, indicating sizable losses at low partial loads.
- The tested devices require cloud connectivity for full functionality and a subscription for dynamic tariffs (about €3.90 per month), and researchers flagged serial‑number‑based vulnerabilities that EcoFlow said it would fix.
- Retailers are pushing deep discounts on Anker’s SOLIX/Solarbank 3 Pro in 2,000 Wp bundles, with prices reported around €1,189 at Yuma, €1,197 at Solarway (with code), €1,199–€1,299 at solago, and €1,289 at Kleines Kraftwerk, often including a Smart Meter.
- Anker’s Solarbank 3 Pro lists about 2.688 kWh base capacity expandable to roughly 16 kWh, an integrated inverter with up to 1,200 W emergency output, IP65 weather protection, multiple MPPT inputs, and app‑based control, with promotional payback estimates varying by usage and tariffs.
