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 3

If you want true home-backup capacity without a fixed installation, the DELTA Pro 3 is the benchmark — huge output, massive expansion and strong solar input. Heavy and pricey, as expected.
