Zendure SolarFlow 800 Pro 2
£837.04 £666.05
Four MPPT trackers, 2640 W of panels accepted and an energy manager that learns your habits: Zendure's top of the range for balcony solar.
- Solar: 2640 W (4 x 660 W), four MPPT trackers
- Power: 1000 W bidirectional AC
- Storage: 1920 Wh built in, 3840 Wh with an AB2000L
- Intelligence: HEMS management and dynamic hourly tariffs
- Four MPPT, the answer to awkward balconies
The SolarFlow 800 Pro 2 is the most complete version of Zendure's balcony power unit. It takes 2640 W of panels across four independent 660 W MPPT trackers, which allows very different orientations without one module penalising the others. Its built-in 1920 Wh battery pairs with an AB2000L extension to reach 3840 Wh, and its 1000 W bidirectional AC output exceeds the rest of the range. An AI-driven energy manager adjusts charging and discharging according to hourly tariffs.
The SolarFlow 800 Pro 2 answers a problem balcony owners know well: perfectly south-facing surfaces are rare. With four independent 660 W MPPT trackers, each panel works at its own maximum power point. A module in shade at the end of the day no longer drags the others down, which genuinely changes things on a block facade where panels often end up on two different planes. That is the real technical argument of this version, more so than the 2640 W ceiling, which few balcony installations will ever reach. The 1000 W bidirectional AC output exceeds the 800 W of the rest of the range, leaving some headroom where local rules allow it, or for faster charging from the grid. The onboard energy manager connects to more than 840 European suppliers and exploits hourly tariffs: it charges when electricity is cheap, discharges when it is expensive, and protects the battery in winter by keeping it above an unfavourable state of charge. On paper, that is what the best domestic systems do, at balcony scale. Two reservations. Expansion stops at 3840 Wh with a single AB2000L battery, where the SolarFlow 800 Plus climbs to 11.52 kWh: if your goal is accumulating capacity, this is not the right model. And since the product is recent, it does not yet have enough reviews to derive a reliable rating, which is why we do not display one.
Zendure SolarFlow 800 Plus
£512.14 £460.85
(3)
Microinverter and battery in a single weatherproof box: 1920 Wh of LiFePO4, 800 W out, and a balcony that keeps supplying power after the sun goes down.
- Storage: 1920 Wh LiFePO4, expandable to 11.52 kWh
- Power: 800 W output, 1000 W grid charging
- Solar: 1500 W (2 x 750 W), two MPPT trackers
- Durability: IP65, outdoor install, 21.1 kg
- Inverter and battery in one, ready to fit
The SolarFlow 800 Plus packs into one enclosure what most balcony installations need in two devices: an 800 W microinverter and a 1920 Wh LiFePO4 battery. It takes 1500 W of panels across two MPPT trackers, also charges from the grid at 1000 W to exploit off-peak tariffs, and climbs to 11.52 kWh with five additional batteries. The whole unit is IP65 rated, so it can live outdoors without a shelter, and is managed from the Zendure app.
Balcony solar has long suffered from one simple flaw: it produces when nobody is home. The SolarFlow 800 Plus tackles that as directly as possible, by putting the battery and the microinverter in a single box. In practice you plug the panels into one side, a domestic socket into the other, and the daytime surplus comes back in the evening instead of flowing into the grid for free. Its 1920 watt-hours roughly match an evening of standby consumption in a flat, router, fridge, lighting and television included. The all-in-one approach has a pleasant consequence: there is no longer any cabling between inverter and battery, so less connectivity to weatherproof, and the IP65 rating lets you set the unit on the balcony without a shelter. The 21 kilos are not trivial, though, and two people are not too many to position it properly. Two things genuinely set it apart from the competition. First, 1000 W grid charging: combined with off-peak or dynamic tariffs, it lets you store cheap electricity at night and give it back during expensive hours, a use that pays for the unit even in winter when solar yields little. Second, expandability: five additional batteries take the system to 11.52 kWh, leaving the door open without replacing anything. The limitation to know is the output power, capped at 800 W by the rules that apply to balcony installations: beyond that you need a proper grid connection. And a 3CT smart meter remains advisable for fine self-consumption control.
Hoymiles HMS-800W-2T
See price and availability (17)
The Hoymiles HMS-800W-2T microinverter feeds 800 W into your home from 2 panels, with built-in Wi-Fi and the know-how of the world's biggest microinverter maker.
- Power: 800 W (800 VA), 230 V output
- Solar input: 2 x 540 Wp max, 2 independent MPPT
- Efficiency: 96.7% (CEC), 99.8% MPPT
- Connectivity: Built-in Wi-Fi, no DTU, IP67
- World's number 1 microinverter maker, 12-year warranty
The Hoymiles HMS-800W-2T is a pure solar microinverter: it turns the DC from 2 panels into 230 V AC fed straight into a household socket, with no storage function at all. With 2 independent MPPT trackers, built-in Wi-Fi (no DTU box needed) and an IP67 casing, it puts reliability first, backed by Hoymiles, the world's largest microinverter manufacturer. A solid base for anyone starting simply with balcony self-consumption, who can still add storage another way later.
On paper, the HMS-800W-2T is nothing exotic: two MC4 connectors for the panels, an AC cable for the wall socket, and that is it. That is exactly what made setup on our test balcony so easy: under twenty minutes between unboxing and seeing the first data in the S-Miles app, with no need to order a separate DTU box as with the older HM-800. The built-in Wi-Fi connects straight to the home router and reports production panel by panel, handy for spotting a badly angled or shaded module straight away. In use, the claimed efficiency roughly holds up, even under a hazy sky, and the casing, genuinely tough-looking with its aluminium heatsink, shrugged off the rain. The real catch, and it is worth being upfront about it, is the total lack of storage: any energy produced and not used on the spot goes straight to the grid, with no chance of getting it back in the evening, unlike hybrid solutions. If you want a simple, rugged device backed by a brand that has been established in this market for years, the HMS-800W-2T gets the job done without frills.
EcoFlow Stream Microinverter
£179.00 £122.55
(12)
The entry-level microinverter of the EcoFlow Stream ecosystem: 800 W output, 2 MPPT, 3 W startup and an IP67 rating rare on this kind of product.
- Grid output: 800 W (2 MPPT, 230 VAC)
- Solar input: 1200 W (2 x 600 W), MC4
- Startup: From 3 W, MPPT range 16-60 V
- Protection: IP67, -40 to 65 C, 10-year warranty
- 800 W plug-and-play microinverter, IP67 and Eco-AI
The EcoFlow Stream Microinverter converts your solar panels' DC into 230 V AC fed into your home through a standard socket. With 800 W of grid output, two MPPT trackers taking up to 1200 W of panels and a startup from just 3 W of input, it produces from dawn to dusk. IP67 rated, compatible with 99% of panels (MC4 connectors) and driven by the EcoFlow app with Eco-AI smart management, it is the plug-and-play, 10-year-warranty gateway to the Stream balcony solar ecosystem.
The Stream is the microinverter with which EcoFlow simplifies the way into balcony solar, and in use it is convincing. Installation genuinely lives up to the plug-and-play promise: you screw on the bracket, clip in the panels' MC4 connectors, plug the supplied mains cable into a socket, and the EcoFlow app walks you through the rest in about fifteen minutes, with no electrician. Two details make the difference day to day. First, sensitivity: the microinverter kicks in from just 3 W of input, so it scavenges energy early in the morning and at dusk, where others stay idle. Second, ruggedness: the IP67 rating, rare on this kind of device, makes it indifferent to driving rain, and it works from -40 to 65 C. App control, with the peak/off-peak mode and the Eco-AI assistant, is clear and gives precise production graphs. Two honest caveats: on its own, without a Stream ecosystem battery, the appeal is limited to daytime self-consumption (unused energy is lost); and the output is capped at 800 W to stay within grid rules, although the hardware could do more. But to start cleanly, it is an excellent base.
APsystems EZ1-M
See price and availability (11)
The APsystems EZ1-M microinverter runs two panels on fully independent MPPT trackers, syncs with the EMA app and carries an IP67 rating built to stay outdoors.
- Output power: 800VA (799VA rated), adjustable from 600W
- Solar inputs: 2 independent MPPT trackers, up to 730Wp each
- Connectivity: Wi-Fi and Bluetooth, AP EasyPower app
- Durability: IP67, -40 to +65°C, 12 year warranty
- 2 independent MPPT trackers, IP67, 12 year warranty
The APsystems EZ1-M microinverter converts the DC output of two solar panels into 230V AC, fed straight into a household socket. Its two fully independent MPPT trackers get the most out of each panel, even when they face different directions. Controlled over Wi-Fi and Bluetooth through the AP EasyPower app, rated IP67 and backed by a 12 year warranty, it targets simple, reliable balcony self consumption, with the option of adding a compatible battery to store any surplus.
Setting up the EZ1-M took under half an hour on our test balcony: two panels facing slightly different directions (one due south, the other shaded for part of the afternoon), the unit mounted under the railing, MC4 connectors clipped in, and the mains cable plugged into a standard socket. Pairing with the AP EasyPower app took minutes via a QR code, with no fiddly account setup. What impressed us most was how genuinely independent the two MPPT inputs are: the shaded panel keeps producing without dragging down the other panel's numbers, which is not something every microinverter at this price manages. The IP67 housing shrugged off several weeks of rain without a hitch. Two honest gripes: without a compatible battery, surplus energy goes straight to the grid instead of being stored, and the list of recognised batteries (Anker E1600, Sunlit BK215) is short next to a full modular ecosystem like Zendure's or EcoFlow's. For a simple, finely adjustable and well documented setup backed by a 12 year warranty, the EZ1-M remains a safe bet in balcony solar.
Zendure SolarFlow 800
£212.89 £127.40
(3)
The 800 W hybrid microinverter that turns a balcony kit into a real energy reserve: 96% efficiency, batteries expandable to 11.52 kWh, plug and play.
- Power: 800 W (bidirectional hybrid)
- Solar input: 1200 W, 2 MPPT trackers
- Storage: Zendure batteries expandable to 11.52 kWh
- Efficiency: 96%, watt-level regulation
- Plug-and-play hybrid microinverter, expandable and affordable
The Zendure SolarFlow 800 is an 800 W bidirectional hybrid microinverter for balcony solar. It plugs into a household socket, takes up to 1200 W of panels (2 MPPT trackers) and manages the charging of Zendure batteries expandable to 11.52 kWh. With 96% storage efficiency, watt-level regulation in under 3 seconds and off-peak grid charging, it is the affordable, expandable gateway to the SolarFlow ecosystem.
Setting up the SolarFlow 800 really is fuss-free: you connect the panels, plug the inverter into a socket, and the Zendure app handles the rest in a few minutes. What changes everything versus a plain microinverter is the hybrid side: as soon as you add a Zendure battery, midday energy is no longer wasted but stored for the evening. In our tests, the switching between solar, battery and grid is impressively quick, and the watt-level adjustment genuinely avoids giving power away to the grid. The claimed 96% efficiency shows in the energy you actually use. We also like the modular logic: you can start small with just the inverter, then grow over time. Two honest caveats: without a battery you are back to a plain microinverter and much of the appeal disappears; and the fine-tuning (off-peak hours, priorities) takes a little time to master. But to get into balcony self-consumption with a well-designed, expandable solution, the SolarFlow 800 is an excellent starting point.
Zendure SolarFlow 800 Pro
£1025.14 £614.75
(3)
The balcony solar storage that finally makes self-consumption pay off: an 800 W inverter, LiFePO4 batteries expandable to 11.52 kWh and smart-home control.
- Inverter: Hybrid 800 W (1000 W off-grid)
- Solar input: 2640 W (4 x 660 W)
- Storage: AB2000X 1920 Wh, expandable to 11.52 kWh
- Technology: 48 V, GaN, IP65, 10-year warranty
- Expandable 48 V balcony storage, run via Home Assistant
The Zendure SolarFlow 800 Pro is an all-in-one storage system for balcony solar that pairs an 800 W hybrid microinverter with LiFePO4 AB2000X batteries expandable up to 11.52 kWh. Its 48 V architecture and GaN components sharply cut losses, while watt-level regulation and deep smart-home integration (up to Home Assistant) maximise self-consumption. IP65 rated and backed by a 10-year warranty, with self-heating batteries that run down to -20 °C.
We hooked the SolarFlow 800 Pro up to an existing balcony setup, and the plug-and-play promise largely holds: the microinverter plugs into a standard household socket, and the Zendure app walks you through setup in a few minutes. The real benefit shows in the evening: energy stored during the day in the AB2000X flows back into the home when consumption peaks, instead of being pushed to the grid for free. Over several weeks, the self-consumption share climbed noticeably. What stood out is how fine the regulation is: the watt-level adjustment really tracks the household's draw, and the response is near instant. Tinkerers will love the Home Assistant integration, which unlocks advanced automations few rivals handle this well. Two honest caveats: the entry price stays high until you stack several batteries to amortise it, and payback depends heavily on your consumption profile and sunlight. But to turn a balcony array into a genuine, expandable storage system with no rewiring, the 800 Pro is one of the most polished options around.
Zendure Hyper 2000
£710.50 £341.15
(3)
The hybrid hub that makes balcony solar genuinely smart: 1800 W MPPT, 1200 W bidirectional output, 4 inputs and batteries expandable to 7.68 kWh.
- MPPT power: 1800 W across 4 solar inputs
- Output: 1200 W bidirectional (feed-in + charging)
- Storage: AB batteries expandable to 7.68 kWh
- Panels: Up to 2400 W of modules
- Hybrid hub, 4 inputs, ZenLink and off-peak charging
The Zendure Hyper 2000 is a hybrid microinverter that packs MPPT trackers, a bidirectional inverter and battery management into a single unit for balcony solar. It takes 1800 W of MPPT power across 4 solar inputs, feeds 1200 W into the home and drives Zendure AB1000 or AB2000 batteries up to 7.68 kWh. With off-peak grid charging, ZenLink multi-set coordination and an IP65 enclosure, it targets optimised self-consumption with no rewiring.
The Hyper 2000 is arguably the most accomplished unit in the SolarFlow range: it brings MPPT, inverter and battery control together in a single IP65 module, and installation stays genuinely plug and play, with no electrician. What stands out in use is the flexibility: four independent solar inputs let you aim panels in different directions without loss, and the 1200 W bidirectional output handles both feed-in and charging the battery from the grid during off-peak hours. In our tests, the adjustment to the home's consumption is fast and the app gives a clear view of production, charge and usage. The ZenLink feature, which coordinates several Hyper units on the same phase, opens the door to scalable installs, up to more than 23 kWh of storage across multiple units. Two caveats: without an AB battery you lose most of the appeal, and the unit costs more than a plain microinverter. But to build a genuinely smart, piece-by-piece balcony power plant, the Hyper 2000 is a remarkably complete foundation.

It converts a panel's direct current into 230 V alternating current right under that panel, instead of routing it through a central inverter. Each module then works independently, which stops a shaded or dirty panel from dragging down the whole string. It is the key component of balcony solar kits.
The microinverter wins on complex, shaded or multi-orientation roofs, and lets you start with two panels then expand. The central inverter stays cheaper beyond 6 kWp on a uniform south-facing roof, and concentrates maintenance at a single accessible point.
It depends on the model: single units drive one panel, duos two, and some models four. Above all respect the ratio between the panels' peak power and the microinverter's: slightly oversizing the panels, by 10 to 20 per cent, is normal and even desirable at our latitudes.
Yes, in most European countries, even for a plug-in balcony installation. In France a declaration to Enedis through the connection portal is required, and the building management must be informed. In Germany, registration in the Marktstammdatenregister is mandatory. The process is free and takes a few minutes.
An optimiser tunes each panel's operating point but leaves AC conversion to a central inverter, which is still required. A microinverter does both and removes the central inverter. The optimiser costs less to buy, the microinverter simplifies installation and eliminates the single point of failure.
