Anker SOLIX F3000

Anker's UK home-backup pick: 3,600W covers most household loads, and it scales from 3kWh to 12kWh as your needs grow. A 4,000-cycle LFP pack and 2,400W solar input make it a credible standing-backup unit, though it trails the DELTA Pro 3 on single-unit output.

EcoFlow DELTA Pro Ultra

The ceiling of what a non-installed, plug-and-play system can do: enough continuous output for a whole home and expansion headroom to 90kWh with extra inverters and batteries. Heavy and expensive — really a whole-home-backup project rather than an impulse buy.
