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. It's the most readily available of these batteries in the UK, but plug-in batteries can't currently be self-installed in Great Britain, so for now it needs an electrician-installed connection.

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. Like all plug-in batteries, it can't currently be self-installed in Great Britain.
