Balkonkraftwerk mit Speicher: Lohnt sich das wirklich? - Ecoflow Stream Ultra Test!

Is a balcony solar power system with storage still worthwhile in 2026? ☀️🔋 The truth is: Many people feed their valuable solar power unused into the grid, essentially giving the energy provider free money. That ends now! In this video, I put the Ecoflow Stream Ultra Basic Set (1800Wp / 3.84 kWh storage) through its paces in a real-world test. I'll show you transparently why the combination of an east-west orientation and storage massively accelerates your return on investment – ​​and why 1800 watts of module output is a game-changer, especially in winter. In this video, you'll learn: ✅ Technical check: How smart meters (Shelly) and emergency power (1200W) work together. ✅ Profitability: My honest calculations – when will you recoup your costs? ✅ Installation: Pitfalls regarding cable lengths, IP protection, and heat (derating). ✅ App control: Prioritize charging vs. grid feed-in for maximum profit. 👉 Plug-in solar simulator HTW Berlin: 🔗 https://solar.htw-berlin.de/rechner/s... 👉 Video links: 📼 PV storage system design:    • PV-Speicher gekauft? Diesen fatalen Fehler...   👉 Product links: 🔗 Official website link: https://de.ecoflow.com/pages/stream-p...
