Anker SOLIX Solarbank 4 E5000 Pro
The most complete balcony battery Anker sells: enough PV input to run seriously oversized panels without clipping losses, off-peak grid charging, and modular expansion to 30kWh. Anker's GB filing for this system was assessed non-compliant for the plug-in route, so it needs a hardwired installation by a qualified electrician. (GBP price representative until Anker publishes the UK RRP.)

Different from the rest: the Venus E has no solar input; it's a plug-in battery for off-peak tariff arbitrage, popular in Germany. In Great Britain plug-in batteries can't be self-installed under the current rules, so it would need a hardwired installation by an electrician.
