Quick answer: For UK buyers in 2026, EcoFlow STREAM has the best UK Amazon availability and the most polished all-in-one ecosystem (base from ~£479, ~£949 with storage). The Anker SOLIX Solarbank 2 (~£899) gives you modular battery storage you can stack to 9.6 kWh, but UK stock is intermittent. Buy STREAM for availability and simplicity; Solarbank if you want expandable storage and can wait for stock. Both respect the UK 800W AC cap.

Buy the EcoFlow STREAM if…
…you want the easiest, best-supported UK purchase. EcoFlow has the deepest UK distribution among balcony brands, so you get fast Amazon UK delivery, UK support, and a mature app. The base kit is cheaper than the Solarbank; add the STREAM Ultra battery later if you want evening storage.
Buy the Anker SOLIX Solarbank if…
…storage is your priority and you want to stack capacity over time (up to 9.6 kWh). The Solarbank 2 is an excellent modular AC-coupled battery with strong time-of-use scheduling. The catch is UK Amazon stock has been intermittent — check availability (Amazon DE with EU shipping is a fine fallback for a UK buyer).
Either way: both need a free G98 notification and (today) a CPS-registered electrician hardwire — see the UK legal status. Model your savings in the calculator.
