Notes from our research: Variants: concrete / lattice / glass balcony; 2 x 400 W (800 Wp), 2 x 450 W (900 Wp), 2 x 520 W (1040 Wp) or 4 x 250 W (1000 Wp, lightweight bracket). No ENA register reference linked. Microinverter specs (all EcoFlow UK STREAM pages identical): 2 MPPT, 600 W max per channel, 65 V max input, 20 V start-up, 16-60 V MPPT range, 16 A max/short-circuit current per MPPT, 800 VA rated output, 3.48 A, 230 V (183-276 V), IP67, -40 to 65 °C, 3.2 kg, 252 x 180 x 35 mm, 10-year warranty, 2.4 GHz Wi-Fi only. Product code EFSTREAMMI800W per Eco Wizard listing. No EcoFlow datasheet PDF found; peak/EU efficiency not published on the UK pages. Panels are EcoFlow 'Rigid Solar Panel' of 400 W, 450 W, 520 W (2 panels) or 250 W (4 panels) depending on variant; panel model, maker and electrical data not given on the UK product pages, so all panel fields are null. Important for UK: the EcoFlow UK FAQ states the BKW DIY cable must be connected to the distribution board by an electrician, i.e. not a plug-in-to-socket install as sold on uk.ecoflow.com.

Good for: Balconies (based on the mounting included)
