Zendure SolarFlow 2400 AC
£1281.64 £1025.15
(6)
AC-coupled storage rated 2400 watts both ways and expandable past seventeen kilowatt-hours, on a battery platform Zendure has since replaced.
- Power: 2400 W charging as well as discharging
- Storage: 2880 Wh LiFePO4 per module, up to 17.28 kWh
- Backup: Off-grid socket, 2400 W continuous, 3600 W peak
- Batteries: AB3000X only, not the AB3000L of the 2400 AC+
- 2400 W bidirectional and 6000 cycles
The SolarFlow 2400 AC is not a microinverter but an AC-coupled home battery: it sits between the meter and the home, absorbs up to 2400 watts to charge and gives back as much when electricity is expensive. The base configuration pairs the unit with an AB3000X battery of 2880 watt-hours in lithium iron phosphate, expandable to 17.28 kWh with six modules, and an off-grid socket takes over during a power cut. One thing to know before ordering: Zendure has since launched the SolarFlow 2400 AC+ and the SolarFlow 2400 Pro, which run on AB3000L batteries, and the two generations share no modules at all.
The SolarFlow 2400 AC marks a change of nature in Zendure's range, and that is worth understanding before buying. The SolarFlow 800 and its derivatives are microinverters: you plug solar panels into them. This one has no photovoltaic input, it is AC-coupled. It sits between your installation and the home, and stores electricity indifferently from your existing panels or from the grid when it is cheap. That is home-battery logic, not balcony-kit logic, and it opens a use case microinverters do not cover: pure tariff arbitrage, profitable without a single panel. The figures follow that ambition. The 2400 watt rating in both directions absorbs a production peak or covers a household's real evening consumption, where the regulatory 800 watts of a balcony kit only erase the standby baseline. Zendure ships the unit set to 800 watts of output by default and allows it to be raised to 2400 watts once an electrician has given it a dedicated circuit, which is a step worth budgeting for rather than discovering afterwards. The 2880 watt-hours of the supplied AB3000X battery represent a full evening for an average household, and stacking to 17.28 kWh puts the system on a par with conventional residential storage. The quoted 6000 cycles on LiFePO4 cells sit within today's serious standards, and the off-grid socket is more generous than the category norm at 2400 watts continuous with a 3600 watt peak. The point that has changed since launch, and the one that should be settled first, is that this unit is no longer the current generation. Zendure has released the SolarFlow 2400 AC+ and the SolarFlow 2400 Pro, both built around a new battery module, the AB3000L, and the brand states that the AB3000L is compatible with those two hubs only and not with the AB3000X or the SolarFlow 2400 AC. Nothing carries across. A 2400 AC already on the wall can only ever be extended with AB3000X modules, which Zendure still sells; a system started today with a 2400 AC is locked to that module for its whole life. That is not a reason to rule it out, since the older platform is discounted and its power rating is higher per module, but it is a decision to take deliberately rather than by accident. Two further points deserve attention before ordering. A compatible smart meter is required for the unit to read household consumption and decide when to charge or discharge, so it is part of the real cost. And the IP65 rating lapses as soon as the off-grid socket is in use or the cover is not properly closed, which Zendure states honestly. The buyer this suits is one who has already worked out the gap between off-peak and peak prices: that is where the payback lies, more than in solar self-consumption.
EcoFlow Stream Ultra X
£1499.00 £1299.00
(13)
3.84 kWh of LiFePO4, a built-in hybrid inverter and up to 2300 W: the EcoFlow Stream Ultra X is the flagship of balcony solar storage.
- Capacity: 3.84 kWh (LiFePO4)
- Output: 2300 W (2 AC outlets) + 800 W grid
- Solar: 4 MPPT, up to 2000 W
- All weather: IP65, self-heating to -20 C
- Battery + built-in inverter, microinverter included
The EcoFlow Stream Ultra X is an all-in-one balcony solar storage system built to maximise self-consumption. It combines a 3.84 kWh LiFePO4 battery, a built-in hybrid inverter and four MPPT solar inputs (up to 2000 W of panels). It stores energy generated during the day to release it in the evening: up to 800 W fed back into the home grid, and up to 2300 W through its two AC outlets. IP65 rated with self-heating down to -20 °C C, it installs outdoors and is controlled by app. The microinverter is included.
The Stream Ultra X is the most accomplished balcony storage system to date. Where most systems settle for a battery module wired to a hub, EcoFlow packs everything into one box: 3.84 kWh of LiFePO4 cells, a hybrid inverter, four MPPT controllers and even two AC outlets. In practice, you plug in your panels (up to 2000 W), store the day's surplus and release it in the evening, either fed back into the grid (800 W, within balcony limits) or straight to its outlets at up to 2300 W during an outage. The IP65 housing and self-heating down to -20 °C C allow year-round outdoor installation, and the app control is thorough. Two reservations: at 39 kg, plan a solid mount and a two-person install, and its price places it firmly at the premium end of balcony solar. But for anyone who wants to maximise self-consumption without stacking boxes, it is a very convincing proposition.
Anker Solix Solarbank 2 E1600 AC
£512.15 (7)
1.6 kWh of AC-coupled solar storage for your balcony: built-in 800W microinverter, dual MPPT, IP65 rating and a capacity expandable up to 9.6 kWh.

- Solar: Dual MPPT, up to 1200W PV input
- AC coupling: Grid charging up to 800W
- Durability: IP65, 6000 cycles, BT/Wi-Fi
- 1.6 kWh AC storage, off-peak, expandable
The Anker Solix Solarbank 2 E1600 AC is an all-in-one balcony solar storage battery with a built-in microinverter and AC coupling. Its distinctive feature: beyond storing your panels' energy (dual MPPT, up to 1200W solar input), it can recharge from the grid (up to 800W) to store electricity during off-peak hours and release it at peak times. With 1600 Wh of LiFePO4 chemistry (6000 cycles, 10-year warranty), IP65 rating and a capacity expandable to 9.6 kWh via BP1600 add-on batteries, it is controlled over Bluetooth and Wi-Fi from the Anker app.
Anker Solix Solarbank 3 E2700 Pro
£1538.99 £896.90
(7)
2688Wh of plug-and-play solar storage: 4 MPPT, a bidirectional 1200W microinverter and an AI that optimises your self-consumption on its own. Balcony solar finally pays off.
- Capacity: 2688 Wh (LiFePO4, expandable 16 kWh)
- Solar: 4 MPPT, up to 3600W PV input
- Inverter: Bidirectional 1200W (800W grid injection by default), plug&play
- Intelligence: Anker Intelligence (AI), meter
- 2688Wh, 4 MPPT, optimising AI
The Anker Solix Solarbank 3 E2700 Pro is a balcony solar storage battery, plug-and-play, that makes home solar genuinely worthwhile. Its 2688 Wh (2.7 kWh) of LiFePO4 store your panels' energy to release it in the evening or at peak hours, instead of losing it. It packs 4 MPPT controllers (up to 3600 W solar input), a bidirectional 1200 W microinverter, and above all Anker Intelligence, an AI that manages the flows on its own to maximise your savings. Its capacity expands to 16 kWh, and a smart meter avoids any waste.
The Solarbank 3 E2700 Pro reconciled us with balcony solar: without it, the energy produced during the day is fed to the grid and lost if no one consumes it; here, you store it to bring it back in the evening, when the home actually needs it. Installation is simple, genuinely plug-and-play, you connect the panels and the microinverter, and the app does the rest. The 4 MPPT let you connect several panels facing different directions with no loss, a real plus on a balcony or facade. What impressed us most is the Anker Intelligence AI: it learns our habits and decides on its own when to store, when to release and how much to feed in, without us having to think about it, which genuinely optimises the savings. The 2688 Wh capacity covers a good part of the evening consumption, and the expansion to 16 kWh lets you go bigger. Two honest caveats: the price remains an investment, to be paid back over several years, and the payback depends on your consumption profile and sunlight. But to make a balcony solar kit finally smart and worthwhile, it is a success.
Zendure AB3000X
£1025.15 £614.75
(6)
The 2880 Wh LiFePO4 module of the SolarFlow 2400 AC generation: 17.28 kWh once stacked, IP65 with aerosol fire suppression, and tied to that one hub.
- Capacity: 2880 Wh (60 Ah, 48 V LiFePO4)
- Expandable: Up to 17.28 kWh with 6 modules
- Power: 2880 W on its own, 3840 W from two modules
- Cold weather: Self-heating from -20 °C to 0 °C
- Safety: IP65, aerosol fire extinguishing system
- SolarFlow 2400 AC only, not the 2400 AC+ or 2400 Pro
The Zendure AB3000X is a 2880 Wh LiFePO4 storage module built for a single hub, the SolarFlow 2400 AC. Zendure's newer SolarFlow 2400 AC+ and SolarFlow 2400 Pro run on a different module, the AB3000L, and the brand states that the two families are not compatible with each other. The AB3000X is therefore the right reference for anyone who already owns a SolarFlow 2400 AC, and the wrong one for anyone buying into the current range. Within its own system it stacks up to six modules for 17.28 kWh, is rated for 6000 cycles, delivers 2880 W on its own and 3840 W from two modules, and comes in an IP65 enclosure with an aerosol fire extinguishing system and a 10-year warranty.
The AB3000X has to be read differently now that Zendure has moved its range on. It is the storage module of the SolarFlow 2400 AC generation, and of that generation alone. The newer SolarFlow 2400 AC+ and SolarFlow 2400 Pro are built around a different module, the AB3000L, which Zendure describes on its own product pages as compatible with those two hubs only and not compatible with the AB3000X or the SolarFlow 2400 AC. The statement runs both ways: an AB3000X will not extend an AC+, and an AB3000L will not extend a 2400 AC. Nothing in the model names makes that obvious, which is precisely why it belongs at the top of the page rather than in a footnote. What makes the split awkward is how close the two modules are on paper. Both hold 2880 Wh, that is 60 Ah at 48 volts of lithium iron phosphate, both are rated for 6000 cycles, both are IP65 and both carry an aerosol fire extinguishing system. The divide is architectural and commercial, not electrical. The one real difference favours the older module: the AB3000X is rated 2880 W on its own and 3840 W from two modules, against 1680 W and 1920 W for the AB3000L. Judged on its own terms the AB3000X is a serious block. Six modules bring the system to 17.28 kWh, the 48 volt architecture keeps conversion losses lower than the low-voltage packs of the previous range, and the self-heating function keeps the module working between -20 °C and 0 °C, which matters for an enclosure that stays outdoors all year. At 26.1 kg it is not something to move about, so its position should be settled before the first bolt goes in, and the 10-year warranty sits at the top of what this category offers. So the advice splits cleanly. If a SolarFlow 2400 AC is already installed, the AB3000X is the only module that will extend it, and Zendure still sells it for exactly that reason. If nothing is installed yet, the choice is between a discounted platform that has stopped evolving and the current one, and it has to be made before the first battery is ordered, because the batteries do not carry across.
Zendure AB2000L
£614.75 £512.15
(6)
The 1920 Wh LiFePO4 storage module of the SolarFlow ecosystem, with aerosol fire suppression: 6000 cycles, expandable to 7.68 kWh, IP65 and a 10-year warranty.
- Capacity: 1920 Wh (LiFePO4, 40 Ah, 48 V)
- Expandable: Up to 7.68 kWh (4 batteries)
- Safety: Aerosol suppression, self-heating -20 C, IP65
- Lifespan: 6000 cycles, 10-year warranty
- Fireproof 1920 Wh stackable battery, affordable
The Zendure AB2000L is a 1920 Wh LiFePO4 storage module for SolarFlow balcony solar systems (Hub 2000, Hyper 2000). It stacks up to four units for 7.68 kWh. It includes an aerosol fire suppression system that smothers any fire without toxic gas, anti-thermal-runaway protection and self-heating down to -20 C. Long-life cells (6000 cycles), an IP65 enclosure and a 10-year warranty make it a reliable, affordable extension for storing your solar energy.
The AB2000L is the new generation of extension battery for SolarFlow hubs (Hub 2000, Hyper 2000): with 1920 Wh per module, it already covers a good part of an evening, at a noticeably gentler price than the previous generation. It keeps the safety pitch that reassures on this kind of permanently installed product: an aerosol fire suppression system that can smother a fire without toxic gas, anti-thermal-runaway protection and an IP65 enclosure for the outdoors. The self-heating, which keeps it charging down to -20 C, makes it a genuine outdoor battery, usable year-round. Stacking remains the ecosystem's great strength: you start with one battery, then add up to four (7.68 kWh). The LiFePO4 cells rated for 6000 cycles and the 10-year warranty reassure over the long run. The only real downside is its weight, which makes it worth choosing its spot carefully at install time. To extend an existing SolarFlow system without breaking the bank, it is now the most logical choice.
Zendure AB1000
£769.50 £426.65
(5)
The 960 Wh LiFePO4 storage module of the SolarFlow ecosystem: compact (11.5 kg), expandable to 3.84 kWh, self-heating -20 C, IP65 and a 10-year warranty.
- Capacity: 960 Wh (LiFePO4, 20 Ah, 48 V)
- Expandable: Up to 3.84 kWh (4 batteries)
- All weather: Self-heating -20 C, IP65
- Weight: 11.5 kg, 10-year warranty
- Compact 960 Wh battery, the most affordable
The Zendure AB1000 is a 960 Wh LiFePO4 storage module for SolarFlow balcony solar systems (Hub 2000, Hyper 2000). Compact (11.5 kg) and compatible with the other AB batteries, it stacks up to four units for 3.84 kWh. Self-heating keeps it charging down to -20 C and the IP65 enclosure allows outdoor installation. With its 10-year warranty, it is the ideal entry-level extension to get into solar storage on a budget.
The AB1000 is the gateway to storage in the SolarFlow ecosystem: at 960 Wh and 11.5 kg, it is the lightest and most affordable of Zendure's extension batteries, ideal for a first step or a small balcony. It carries the essentials: an IP65 enclosure for the outdoors, self-heating that keeps it charging down to -20 C, and the range's stacking logic (up to four units, or 3.84 kWh, and compatible with the other AB batteries to size your capacity). The 10-year warranty covers the whole thing. Two things to keep in mind: its capacity stays modest, so for genuine evening autonomy you are better off with the AB2000L or stacking several modules; and, unlike the newer versions, it does not have the aerosol fire suppression system reserved for the higher-end models. But to start out without investing too much and discover balcony storage, the AB1000 remains an excellent entry point.
Zendure AiO 2400
£1538.14 £1025.15
(2)
The all-in-one solar storage that combines a hub and a 2400 Wh battery in a sleek metal case: 2 MPPT, self-heating to -20 C, IP65 and easy install.
- Capacity: 2400 Wh built-in (LiFePO4, 48 V)
- Solar input: 1560 W, 2 MPPT controllers
- Design: All-in-one hub + battery, pairs with a microinverter
- All weather: Self-heating -20 C, IP65
- All-in-one 2400 Wh balcony storage with design
The Zendure AiO 2400 is an all-in-one solar storage unit for balcony solar that combines the management hub (PV-Hub) and a 2400 Wh LiFePO4 battery in a single case. With two MPPT controllers (up to 1560 W of panels, 1200 W for charging), it connects to a microinverter to feed the stored energy in. Its slim metal design, self-heating down to -20 C and IP65 rating make it a polished, easy-to-install way to store your solar energy all year round.
The AiO 2400 takes the opposite approach to modular SolarFlow systems: instead of stacking a hub and batteries, everything sits in a single metal case, slim and genuinely elegant, one of the best-looking in the category. In use, its simplicity is what wins you over: you connect the panels to its two MPPT inputs, link a microinverter (often the bundled EZ1-M), and the built-in 2400 Wh battery does the rest, storing daytime energy to release it in the evening. The self-heating that keeps it charging down to -20 C and the IP65 rating make it a true outdoor product, usable year-round. The LiFePO4 cells last up to 4000 cycles at 80% (8000 at 70%), a sign of longevity, and the 10-year warranty reassures. Two caveats: its capacity is fixed (2400 Wh), so you need to size it right at purchase, with no stacking like on an AB system; and you have to add a microinverter for feed-in. But for a clean, good-looking, fuss-free balcony install, the AiO 2400 is one of the best options around.
Zendure SolarFlow 4000 Mix AC+
2599.00€ 2399.00€
(2)
The retrofit that changes scale: 8 kWh expandable to 50 kWh, 4 kW bidirectional power, and a dedicated input for your existing solar inverter.
- Capacity: 8000 Wh LiFePO4, expandable to 50 kWh
- Power: 4000 W bidirectional, 5000 W in PV bypass
- Backup: Off-grid output 3680 W, 7200 W peak
- Resistance: IP65, -20 to +55 °C, 80 kg
- 5 kW input for your existing PV inverter
The Zendure SolarFlow 4000 Mix AC+ is an AC-coupled home battery designed for households that already have solar panels and an inverter in place. A dedicated 5000-watt input plugs straight into third-party inverters (Huawei, SMA, Fronius, Enphase, SolarEdge, Sungrow...) without touching the existing installation. Capacity starts at 8000 watt-hours and expands to 50 kWh, bidirectional power reaches 4000 watts, and a 3680-watt backup output (7200 watts peak) takes over during a power cut.
The SolarFlow 4000 Mix AC+ has only just gone up for pre-order, and the handful of early customer reviews already set the tone: one buyer describes wiring it straight into a 20A breaker rather than a wall socket, a cleaner install in his view, and says he already raised output to 3000 watts without a hitch. The ZenKi mode, meant to learn the household's consumption habits, currently favours solar during the day and charges during off-peak hours, matching Zendure's stated promise. On paper, the 10-millisecond switchover to the off-grid output and the 7200-watt peak leave headroom for appliances with a high starting current, such as a heat pump. The real caveat at this stage is the lack of hindsight: the product has only just launched, reviews are still countable on one hand, and the pre-order shipping window (20 to 30 days) is worth watching before ordering. Once the rumoured 7 kWh expansion module ships, as one of the first buyers already hopes, the system should gain even more flexibility.
Bluetti Balco 260
1399.00€ (1)
The Bluetti Balco 260 stores your balcony solar power in 2560Wh of LiFePO4, expandable up to 15.36kWh, with no electrician required.
- Capacity: 2560Wh (LiFePO4, expandable to 15,360Wh)
- Solar: 4 MPPT trackers, up to 2400W PV input
- Power: 1200W bidirectional, up to 2300W peak
- Resistance: IP65, -20 to 50 °C, 10-year warranty
- Expandable to 15.36kWh, 4 MPPT, no electrician needed
The Bluetti Balco 260 is a plug-and-play balcony solar storage battery: 2560Wh of LiFePO4, four MPPT inputs accepting up to 2400W of solar panels, and a 1200W bidirectional inverter (2300W peak) that feeds power straight into your home, no electrician required. Capacity scales up to 15,360Wh with additional BC260 batteries, and up to 92kWh when networking several units through the BLUETTI Space app.
The Balco 260 is a genuine step forward for anyone living in a flat: plugging a 2560Wh battery capable of soaking up 2400W of solar panels through its four MPPT trackers straight into a wall socket, with zero electrician required, is a promise it actually keeps. Setup is genuinely quick, and the app handles charging and discharging around electricity tariffs thanks to its built-in AI (AI-EMS). Its real strength is scalability: up to five extra BC260 batteries push capacity to 15,360Wh, and up to six units can coordinate wirelessly to cover an entire home. A few caveats are worth flagging: early independent tests measure round-trip efficiency around 79%, behind the best competitors, and standby draw a touch higher than Bluetti's own figures. The automatic charging mode has also shown a few questionable calls in early testing. Nothing dealbreaking for a first-generation product, but worth watching through future updates. As an uncomplicated way to start balcony solar storage, the Balco 260 remains a solid, scalable choice.
Allpowers BS2500 Pro
£1709.14 £1025.15
2600Wh of plug & play solar storage: the hybrid balcony battery that stores your production to release it in the evening and finally make self-consumption pay off.
- Capacity: 2600 Wh (LiFePO4)
- Power: 2400 W, hybrid grid/off-grid
- Solar: Dual MPPT, anti-backflow
- Protection: IP65, plug & play
- 2600Wh, hybrid, dual MPPT, IP65
The Allpowers BS2500 Pro is a plug & play home solar storage system designed for balconies and facades. With 2600 Wh of capacity and 2400 W of power, it stores your panels' energy to release it in the evening or at peak hours, instead of losing it. Hybrid (grid and off-grid), it packs a dual MPPT to connect several panels, an anti-backflow protection, a durable LiFePO4 battery and an IP65 rating for the outdoors. The simple way to make solar self-consumption genuinely worthwhile, with no heavy work.
The BS2500 Pro reconciled us with balcony solar. The principle is clear: without storage, the energy produced during the day goes to the grid and is lost if no one consumes it; here, you keep it to release it in the evening, when the home actually needs it. Installation lives up to its plug & play promise, you connect the panels and the inverter, and the system handles the rest. The dual MPPT lets you connect several panels, even facing different directions, with no loss, a real plus on a balcony. The anti-backflow protection avoids sending unwanted current back to the grid, and the IP65 rating is reassuring for an outdoor install. Its 2600 Wh capacity covers a good part of the evening consumption. Two honest caveats: the price remains an investment to be paid back over several years, and the payback depends on your consumption profile and sunlight. But to make a balcony solar kit finally smart and worthwhile, the BS2500 Pro is a success.

Rated IP65 and for use from -20 to 55 degrees C, it can be expanded to 15 kWh per tower with EB5000 battery packs, and up to 90 kWh by combining several towers. Announced on 20 August 2026, it remains on pre-order in most markets.
Related questions
It's a storage battery that already has everything it needs to run on its own: a bidirectional inverter, a charge controller, and often a control app. It plugs straight into a wall socket or into your existing panels, with no complex wiring and no need for a professional.
No, that's the whole point of this format: plugging into a standard mains socket, or into an existing solar inverter, is enough. A professional is only needed for a direct connection to the fuse board, which stays optional depending on the model.
Work out the evening and overnight consumption you want to cover: a household using 1 to 2 kWh in the evening is already well served by an entry-level model around 1 to 2.5 kWh, while a whole house will more likely need 5 kWh or more, with the option to expand capacity with extra modules on most ranges.
It depends on the model: some offer a backup output that switches over within milliseconds to power priority devices, others don't. Check this spec on each product page before buying if that use case matters to you.
Yes, that's actually one of the main uses: AC-coupled models sit downstream of an existing solar inverter, without touching the installation already in place, to add storage to a system that didn't have any.
