Best Portable Power Stations for Plug-in Solar UK 2026
Three batteries, three price points, three use cases. Here's which portable power station pairs best with your plug-in solar setup.
Adding battery storage to a plug-in solar system is the single most impactful upgrade you can make after the panels themselves. A battery captures surplus daytime generation that would otherwise be exported unpaid, and shifts it to evening use when you'd be paying grid rates.
The UK portable power station market has settled around three serious contenders for plug-in solar pairing. Here's how they compare.
The Three Contenders
EcoFlow DELTA 2 — Best All-Rounder
Price: ~£599 | Capacity: 1,024Wh | Weight: 12kg
The EcoFlow DELTA 2 is the default recommendation for a reason. It hits the sweet spot between capacity, price, and ecosystem integration. LFP (lithium iron phosphate) chemistry gives 3,000+ cycles to 80% capacity — over 8 years of daily use. The EcoFlow app is the most polished of the three, with charge scheduling, output limits, and clear real-time monitoring.
Solar input maxes at 500W via MC4, meaning your 800W system can charge it directly (the DELTA 2's MPPT controller handles the conversion). Alternatively, charge via AC from your ring main during cheap overnight hours if you're on a time-of-use tariff.
Best for: most plug-in solar owners wanting a reliable, well-supported battery at a sensible price. Particularly strong if you're already in the EcoFlow ecosystem with the STREAM kit or 400W panel.
Anker SOLIX C1000 Gen 2 — Best Specs
Price: ~£799 | Capacity: 1,056Wh | Weight: 12.9kg
The Anker SOLIX C1000 Gen 2 is the newest of the three, with marginally more capacity and a more modern design. LFP chemistry with 3,000+ cycle rating. The SurgePad technology allows 2,400W surge output — higher than the DELTA 2 — which matters if you plan to run high-draw appliances briefly (kettles, microwaves).
Anker's app is competent though slightly less refined than EcoFlow's. Solar input maxes at 600W — more headroom than the DELTA 2 if you're running larger panel arrays or planning expansion.
Best for: households wanting the highest capacity and surge power. Worth the premium if you plan to use the battery for occasional off-grid appliance use (power cuts, garden office, workshop) alongside the solar storage role.
Jackery Explorer 1000 v2 — Best Portability
Price: ~£499 | Capacity: 1,070Wh | Weight: 10.8kg
The Jackery Explorer 1000 v2 offers similar capacity to the other two at a lower price and lighter weight. It uses a slightly older NMC lithium-ion chemistry rather than LFP, which means a lower cycle rating (around 1,000 cycles to 80% — roughly 3 years of daily use). Charge rate via solar is limited to 200W, which is slower than the competition.
Best for: owners who want dual-use — a home solar battery that also goes camping, to the allotment, or in the caravan. The lighter weight and carry handle make it genuinely portable. If your primary use is home storage and you won't move it often, the DELTA 2 or C1000 are better value due to their superior cycle life.

- Store daytime solar for evening use
- Full home backup mode
- Smart scheduling via EcoFlow app
The Financial Case for Each
The core calculation is the same for all three: how much surplus solar are you currently exporting unpaid, and how much can the battery capture?
For a household exporting 1-2 kWh per day (typical for an 800W system when residents are out during the day), the annual value of captured electricity is roughly £88-175 at 24p/kWh.
DELTA 2 payback: £599 ÷ £88-175/year = 3.4-6.8 years SOLIX C1000 payback: £799 ÷ £88-175/year = 4.6-9.1 years Jackery 1000 v2 payback: £499 ÷ £88-175/year = 2.9-5.7 years (but NMC degradation means less capacity retained over time)
On a time-of-use tariff, the overnight/daytime price spread adds another £50-80/year, reducing payback across the board.
The Jackery has the shortest pure financial payback but the shortest useful life (NMC chemistry degrades faster). Over a 10-year horizon, the LFP batteries (DELTA 2 and C1000) retain more capacity and deliver more total value.
Can You Expand?
EcoFlow — the DELTA 2 accepts add-on batteries (DELTA 2 Extra Battery) to double capacity. This is useful if your first year of monitoring shows you're exporting more than 1 kWh per day. The expansion battery connects directly to the DELTA 2 without additional inverter hardware.
Anker — the C1000 supports expansion via the SOLIX BP1000 add-on battery, similarly doubling capacity.
Jackery — no direct battery expansion option for the Explorer 1000 v2. To increase capacity, you'd need to buy a second unit (which can't be linked to the first).
Which to Buy
If budget is the primary concern and you want dual-use (home + camping/caravan): Jackery Explorer 1000 v2. Accept the lower cycle life and plan to replace or upgrade in 3-4 years.
If you want the best balance of price, performance, and longevity: EcoFlow DELTA 2. The LFP chemistry, expansion option, and excellent app make it the default recommendation.
If you want the highest capacity and surge power, and budget allows: Anker SOLIX C1000 Gen 2. The better surge rating and newer design justify the premium for power-hungry households.
Before You Buy
Don't buy a battery before you have data. Install your plug-in solar system, fit a Tapo P110 to the inverter output, and monitor for at least one month — ideally a full season. This tells you:
- How much you generate daily
- How much you self-consume vs export
- Whether your consumption pattern makes battery storage financially worthwhile
