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. Priced as a premium anchor rather than a starter — and one you won't outgrow. (GBP price representative until Anker publishes the UK RRP.)

Marstek Venus E

Different from the rest: the Venus E has no solar input — it's a plug-in battery for off-peak tariff arbitrage. On a tariff like Octopus Agile it can pay back through cheap-rate charging even without panels.
