Overview
- Home&Smart highlights a Yuma offer pairing four bifacial panels (about 2,340 W DC) with an EcoFlow STREAM Ultra storage unit (3.84 kWh) for €949, including a smart meter and €450 off the usual price.
- InFranken details additional EcoFlow Stream Ultra X bundles via Powerness from €1,199 for pickup, with modular options, IP65 weatherproofing, four MPPT inputs and 10‑year warranties.
- Current guidance reiterates compliance: simplified procedures apply only up to 800 W feed‑in per end circuit, one generation device per end circuit under VDE V 0100‑551‑1:2018‑05, registration in the Marktstammdatenregister is required and storage use should be notified to the grid operator.
- Multiple setups are possible across different household phases, and East‑West configurations can smooth output; some guides describe linking micro‑inverters via a Betteri AC connector as a legal and safety gray area that warrants caution.
- Analyses show mini‑PV can materially cut bills with typical yields around 700–1,200 kWh per year, while expert data cited by Chip.de indicates payback of roughly 3.5 years without storage versus just over eight years with a battery, and retailers tend to offer the deepest price cuts in November and early winter.
