EcoFlow STREAM Ultra
A capable all-in-one system, with 2,000W of PV input across four trackers and a built-in battery, and one of Europe's best-sellers. But in Great Britain the built-in battery rules it out of the plug-in route: it can't be self-installed under the current rules. Worth watching if plug-in batteries are allowed after DESNZ's safety study.

Zendure's strength is modular storage: begin with a 0.96kWh module and stack more later. That built-in storage is exactly what the UK plug-in rules exclude, so it can't be self-installed in Great Britain for now.
