EcoFlow has grown from a camping gadget brand into one of the most visible names in UK home energy storage. Their products now span plug-in home batteries, portable power stations, solar panels, and a standalone microinverter. The range is wide enough to be genuinely confusing — this guide maps out every current UK product and who each one suits.

The EcoFlow STREAM series: plug-in home batteries

The STREAM series is EcoFlow's answer to a specific problem: how do you add battery storage to a home without scaffolding, planning permission, or a G98/G99 network operator application? The answer is a wall-mounted unit that charges from the grid or from solar panels, then feeds 800W back into your home's AC circuits through a standard 13A plug socket on the battery's output side.

Every STREAM unit shares the same core specifications:

  • Battery: 1.92 kWh LFP (LiFePO₄), 6,000 cycles to 70% capacity
  • Warranty: 10 years
  • Grid output: 800W rated (230V~, 50Hz)
  • Max device load: 2,300W (battery output + simultaneous grid draw)
  • IP rating: IP65
  • App control: EcoFlow App (Wi-Fi + Bluetooth)
  • G99 grid connection approval (UK)
  • Self-heating at ≤5°C for cold-climate operation

Where they differ is the number of direct solar (MPPT) inputs. The table below covers the full UK lineup:

ModelApprox. priceMPPT channelsMax solar inputBest for
STREAM AC£6890None (AC only)Grid arbitrage, no solar
STREAM AC Pro£69921,200W1–2 panels, entry solar
STREAM Max£87921,000W2 panels, mid-range
STREAM Pro£82331,500W3 panel strings / mixed orientations
STREAM Ultra£94942,000WUp to 4 panel strings, maximum solar
STREAM Ultra X~£1,400 est.42,000WDouble battery (3.84 kWh), 4 strings

Prices EcoFlow UK direct, inc. VAT. Retailer prices vary — verify before purchasing.

All models except the Ultra X stack up to six units for a maximum of 11.52 kWh. The Ultra X, with its doubled 3.84 kWh cell, can reach approximately 23 kWh across six units.

Optional accessory: EcoFlow × Shelly Smart Meter

EcoFlow and Shelly have an official co-branded smart meter — the EcoFlow × Shelly Smart Meter (Shelly Pro 3EM) — that upgrades the STREAM from a tariff-arbitrage device into a solar self-consumption optimiser. It mounts inside your consumer unit (professional installation required — Part P notifiable work) and monitors your real-time grid import and export. The EcoFlow app uses this data to divert surplus solar into the STREAM battery rather than letting it export to the grid at low SEG rates. Compatible with STREAM AC Pro, Pro, and Ultra. Price: £149 (EcoFlow UK direct).

For the full explanation of how zero-export diversion works and what it adds to the system, see the STREAM series guide.

STREAM Microinverter: the solar input component

The STREAM Microinverter is the component that converts DC electricity from solar panels into AC electricity that can feed your home's circuits or charge a STREAM battery. It is sold separately and is worth understanding on its own terms.

Grid approvalG99 (UK)

The microinverter works with any STREAM battery unit and also with third-party batteries that accept AC input. If you already own a balcony solar panel and want to add the inverter component, the STREAM Microinverter is worth considering.

G99 hardwired installation required in the UK

Despite EcoFlow's "plug-in solar" marketing language, the STREAM Microinverter cannot be connected via a 3-pin plug socket in the UK. UK regulations require permanent electrical installation by a qualified electrician and G99 notification to your Distribution Network Operator. The EU 600W variant can use a Schuko plug in some countries — the UK 800W model cannot. Budget for an electrician visit before purchasing.

EcoFlow Delta Pro 3: flagship portable power station

The Delta Pro 3 sits in an entirely different category from the STREAM series. It is a portable power station — a large, self-contained unit with a built-in inverter, wheels, and a handle. Think serious off-grid capability, camping with high-draw appliances, or whole-home emergency backup — not day-to-day grid arbitrage.

SpecValue

Charge speed0–80% in ~50 min (EV charger / X-Stream)

Warranty5 years

The 6,000W X-Boost output is notable: it lets you run appliances rated above the unit's continuous 4,000W using a form of intelligent load management. The Delta Pro 3 will power a kettle, electric oven, or workshop equipment that smaller power stations cannot handle.

The Delta Pro 3 is stocked by EcoFlow UK direct and Costco UK. It is primarily sold through specialist retailers rather than Amazon.

The entry in data/products.json for ecoflow-delta-pro covers the older Delta Pro (3.6 kWh, £1,198 on Amazon). The Delta Pro 3 is a newer, larger generation — if you see the older product listed at a lower price, confirm the generation before purchasing.

Delta Pro 3 vs STREAM: which is for you?

If you want to reduce your electricity bill day-to-day by storing cheap-rate grid power or solar energy, the STREAM series is the better fit — it is designed for fixed installation and continuous cycling. The Delta Pro 3 excels for high-power portable use: motorhome trips, off-grid cabins, building sites, or as a large backup unit for power cuts.

EcoFlow RIVER 2 series: compact portable power

The RIVER 2 family is EcoFlow's lighter, more affordable portable power range. All three models use LFP chemistry (~3,000 cycle life) and charge to 100% in around an hour from a wall socket. They are designed for camping, festivals, garden power, and light emergency use.

RIVER 2 Pro768 Wh800W (1,600W X-Boost)~7.8 kg£499

RIVER 2 Pro solar input spec not confirmed from available sources — check EcoFlow UK direct.

The RIVER 2 is genuinely pocketable for its capacity: 3.5 kg and 256 Wh covers phone charging, a CPAP machine overnight, or a full day of laptop use. The RIVER 2 Pro at 768 Wh is the most practical choice for a long weekend off-grid — its 800W continuous output handles a small induction hob at reduced settings.

Pair any RIVER 2 with EcoFlow's portable solar panels (see below) via MC4 connectors for a self-sufficient off-grid setup.

Both the RIVER 2 and RIVER 2 Pro are available on Amazon UK as well as EcoFlow UK direct.

EcoFlow portable solar panels

EcoFlow's portable panel range covers 110W to 400W and is compatible with every STREAM, Delta Pro, and RIVER product via standard MC4 connectors. All models fold flat for transport and storage.

ModelWattageEfficiencyWeightUK price
110W Panel110W~22%~4.1 kg£199
NextGen 160W160W25% (TOPCon N-type)5.6 kgCheck EcoFlow UK
220W Lightweight220W25% (TOPCon N-type)4.4 kg£349
220W Bifacial220W~23%9.5 kg~£359
400W Panel400W22.4%16 kg£649

A few standout points from the range:

220W Lightweight vs 220W Bifacial: The Lightweight panel uses TOPCon cells and weighs 4.4 kg — less than half the Bifacial's 9.5 kg. For van life or camping where you're carrying the panel, the Lightweight is the practical choice. The Bifacial model captures light from both faces, making it more interesting for ground-mounted use where reflected light from paving or grass hits the rear — a modest but real gain in low-angle or diffuse UK light conditions.

400W Panel: This is a substantial piece of kit — think semi-permanent garden deployment rather than carried camping use. It is IP68 rated and chainable (two panels can be connected in series or parallel to maximise input to a Delta Pro 3 or STREAM Ultra).

NextGen 160W: Uses the same TOPCon Type-N cell technology as the 220W Lightweight, achieving 25% efficiency in a smaller folded footprint. Worth considering if you need more wattage than the 110W but want a compact package.

All portable panels work with the STREAM Microinverter via MC4 — you can use them in a balcony solar setup if you have the required hardwired inverter installation.

Which EcoFlow product is right for you?

The EcoFlow range spans very different use cases. Here is a decision guide:

"I rent a flat with a south-facing balcony" Consider the STREAM Ultra paired with balcony-mount solar panels. The Ultra's four MPPT channels handle multiple small panels across a balcony railing. You will still need a hardwired installation for the STREAM Microinverter — budget for an electrician — but the battery itself plugs in via a standard 13A socket.

"I want to cut my electricity bill using cheap overnight rates but I don't have solar" The STREAM AC at £689 is the entry point. It has no solar inputs — it charges purely from the grid overnight (for example on a cheap overnight tariff) and discharges during the day, offsetting the higher peak rate. No solar required, no panels, no roof work.

"I go camping or motorhoming regularly" The RIVER 2 Pro (£499, 768 Wh) paired with a 220W Lightweight panel (£349) gives you a capable off-grid setup under 13 kg combined. The RIVER 2 Pro's 800W continuous output handles most camping appliances including small induction hobs.

"I need serious portable power — off-grid cabin, building site, long-term van life" The Delta Pro 3 (£2,799, 4,096 Wh, 4,000W AC) is in a different league from the RIVER 2 series. Its 6,000W X-Boost mode handles high-draw power tools and cooking appliances. Expand to 12.3 kWh with two extra batteries.

"I already have balcony solar panels connected to a microinverter — I want storage" The STREAM AC (£689) accepts AC from any microinverter, so you can pair it with your existing setup without replacing the inverter. If your current inverter is not outputting to a battery, you may need to check compatibility with your installer.

"I want to add a standalone microinverter to my existing panels" The STREAM Microinverter at £129–£179 is worth exploring. It connects to any pair of standard solar panels via MC4 and outputs 800W AC. But note — in the UK this must be hardwired by a qualified electrician under G99. There is no 3-pin plug option in the UK.

STREAM is not a whole-home battery system

The STREAM series outputs 800W maximum to your home circuits — enough to cover background loads (fridge, lights, router, TV) but not your kettle, oven, or immersion heater simultaneously. If you want a system that covers your whole home including high-draw appliances, look at professional installations such as the GivEnergy All-in-One or Tesla Powerwall 3, which output 3–11 kW. The STREAM is best understood as a bill-reduction tool rather than full home backup.
