EcoFlow STREAM AC Pro

The natural upgrade path if you started with a STREAM microinverter: stack it under the inverter and your clipped surplus goes into storage instead of nowhere. AC-coupled mode means it also earns its keep on a time-of-use tariff before you buy a single panel. The only genuinely UK-stocked battery of the three, though it sells out fast.

Zendure SolarFlow 800 Pro

DC-coupled, so the panels feed the battery directly and surplus is caught before the 800W bottleneck — the right architecture if you're running big arrays. Strong value per stored kWh, but UK buyers currently have to import via specialist retailers rather than a Zendure UK store, so factor in shipping and thinner local support.
