EcoFlow PowerStream
Worth considering if you already own an EcoFlow Delta/River power station — PowerStream turns it into balcony-solar storage. Otherwise the newer STREAM line is the better buy.

The standout balcony system in 2026: a legal 800W output, generous 2,000W of PV input across four trackers, and a built-in battery so evening usage is covered. Expandable if you want more storage later.
