EcoFlow STREAM Ultra All-in-One Plug-In Solar Battery (1.92kWh)This article does a good job of explaining the differences between ecoflow products.
The EcoFlow STREAM Ultra is a plug-in solar battery system designed for UK balcony, garage, and small home solar setups. It combines a lithium LFP battery, hybrid microinverter, and smart MPPT solar charging into a single unit, allowing solar generation, storage, and usage without a traditional full PV installation.
Key features:
1.92kWh LiFePO4 battery (long-life, 6000 cycles)
Up to 2000W solar input via 4 MPPT trackers
Up to 1200W AC output per unit (higher when paired in parallel)
Smart app control with AI-driven load shifting (time-of-use optimisation)
Expandable system (multi-unit scaling up to 11kWh)
IP65 weather resistance and outdoor-ready design
Designed for plug-in solar and self-consumption setups in the UK
2 year warranty
Stores excess daytime solar and shifts it into evening usage, reducing grid reliance and improving self-consumption efficiency. Particularly effective for east/west roof splits and partially shaded installs.
