Best Solar Batteries for Evening Use in the UK

The Evening Problem

Plug-in solar generates electricity during daylight hours, but most UK households use the bulk of their electricity between 5pm and 10pm — cooking, heating, lighting, screens. Without storage, your free solar energy feeds the grid while you pay full price for evening electricity.

A portable power station solves this neatly. Charge it from solar during the day, draw from it during peak evening hours. The maths is straightforward: shift 3–5kWh of daily demand from grid to stored solar, and you're saving £1–2 per day at current rates.

What to Look For

Three things matter for evening use specifically. First, capacity: you want at least 1kWh (1,000Wh) to cover a meaningful evening. A typical UK evening uses 2–3kWh, so 2–3kWh of storage covers most households. Second, LiFePO4 chemistry: you're cycling this battery daily, so you need 6,000+ cycle life, not the 1,000 cycles you get from older NMC batteries. Third, AC output: you need standard UK plug sockets to run normal appliances.

EcoFlow DELTA 2 (~£600–800)

The DELTA 2 is the most popular entry point. 1,024Wh capacity with a 1,600W inverter — enough to run a TV, lighting, laptop, and phone charging simultaneously. The app is excellent for tracking charge/discharge cycles, and you can expand capacity later with add-on batteries.

For evening use specifically, the DELTA 2's scheduling feature is genuinely useful: set it to charge only during solar peak hours and discharge from 5pm onwards.

Anker SOLIX C1000 (~£800–1,000)

The C1000 Gen 2 offers 1,024Wh with a 2,000W inverter — more headroom for high-draw appliances. Anker's 10-year warranty is industry-leading, and the build quality reflects years of battery manufacturing experience.

It's lighter than the DELTA 2 at equivalent capacity, which matters if you're moving it between rooms or taking it camping on weekends. The app is functional rather than flashy, but it tracks everything you need.

Jackery Explorer 1000 v2 (~£500–700)

Jackery's refreshed 1000 v2 packs 1,070Wh of LiFePO4 with a 1,500W inverter. It's the no-nonsense option: solid build, reliable performance, and a straightforward interface. The v2 charges faster than its predecessor — 0 to 80% in under an hour from AC.

If you want something that just works without fuss, Jackery is hard to fault. Less smart-home integration than EcoFlow, but fewer software headaches too.

How Much Can You Actually Save?

At 27p/kWh (current UK average), shifting 2kWh of evening demand to stored solar saves roughly 54p per day — about £197 per year. A £700 battery pays for itself in under 4 years, then generates pure savings for the remaining 10–15 years of its lifespan.

The real savings come from combining storage with a time-of-use tariff (like Octopus Agile), where evening rates can hit 40p/kWh or more. In that scenario, payback drops to under 3 years.

Which One?

EcoFlow DELTA 2 if you want the best app and smart scheduling. Anker SOLIX C1000 if you want the longest warranty and lightest weight. Jackery Explorer 1000 v2 if you want simplicity and value.

All three are LiFePO4, all three have UK plug sockets, and all three will comfortably cover your evening electricity for years. Start with 1kWh and expand if you find you want more.
