Battery System Review
Zendure SolarFlow Review: UK Balcony Solar Battery Verdict
The battery system that works with the microinverter you already own. We've verified the specs, tracked down real UK pricing, and compared it honestly against EcoFlow and Anker.
Quick Verdict
The most microinverter-agnostic balcony battery you can buy — the hub slots between your existing panels and inverter, so you keep what you own. Excellent hardware and warranty, let down by patchy UK availability and a fiddlier setup than its rivals.
Rating: 3.5/5 · UK kits from ~£650 (hub + microinverter + 1 kWh battery)

What the Zendure SolarFlow Actually Is
Most balcony solar batteries — the Anker Solix Solarbank being the obvious example — are all-in-one units with the inverter built in. The classic Zendure SolarFlow takes a different approach. It's a PV hub plus stackable batteries: the hub sits in the DC cable run between your solar panels and your microinverter, and decides in real time whether generation goes straight into your home or into storage.
That matters for one simple economic reason. The Smart Export Guarantee currently requires MCS certification, which most DIY balcony installs can't get — so any electricity you export to the grid earns you nothing. A battery lets you shift your midday surplus to the evening and actually use it. Storing what you'd otherwise give away is the whole economic case — our self-consumption guide runs the numbers in detail.
Because the hub is inverter-agnostic, Zendure claims compatibility with the vast majority of microinverters — Hoymiles, APsystems, Deye and others — over standard MC4 connectors. If you already own a panel-and-inverter setup and want to add storage, that's a genuine advantage over buying into a closed ecosystem. As with any grid-connected generation in the UK, you should submit a G98 notification to your DNO before plugging in, and keep the AC output at or below the 800W level the UK's simplified rules are being built around.
Confusingly, “SolarFlow” is now a family, not one product. The classic Hub + AB-battery system is what most UK kits contain; the newer SolarFlow 800 series (2025) builds an 800W inverter into the battery unit itself, and the Hyper 2000 is an AC-coupled unit that can also charge from cheap overnight grid rates. In April 2026 Zendure refreshed the battery line again with the AB2000X and AB3000X modules. The specs below cover the configurations you can realistically buy in the UK today.

How It Compares to EcoFlow STREAM and Anker Solix
All three brands now solve the same problem — storing your unpaid midday surplus — but they carve it up differently.
Where SolarFlow has the edge
- • Works with the microinverter you already own — no ecosystem lock-in
- • 10-year warranty vs 5 years on EcoFlow and Anker inverter units
- • Stacks to 7.68 kWh (classic) or 11.52 kWh (800 Pro) — Anker's Solarbank 2 Pro is fixed at 2 kWh
- • Cheapest UK entry into battery storage at ~£650 all-in
Where the rivals have the edge
- • EcoFlow STREAM: better app, IP67 inverter, larger UK community — see our full STREAM review
- • Anker Solarbank: simpler one-box install, stronger UK retail presence — see our Anker Solix review
- • Both are easier to buy in the UK, priced in pounds, with UK support

What Reviewers Agree On
Consistent praise across sources
- +Inverter-agnostic hub design — add storage to an existing setup without replacing anything
- +Solid LFP battery hardware with self-heating for UK winters and silent operation
- +10-year warranty is the longest in the balcony solar category
- +Modular expansion lets you start at 1–2 kWh and grow as budget allows
- +Hyper 2000 variant can charge from cheap overnight grid rates as well as solar
Consistent criticisms across sources
- −No official Zendure UK store — one main UK specialist retailer, euro pricing elsewhere
- −Setup is fiddlier than EcoFlow or Anker: more boxes, more cables, more app steps
- −App is functional but a clear step behind EcoFlow's, with a slow AI learning period
- −Schuko-first design means a UK plug adapter, like most of the category
- −Confusing product naming — Hub 1200/2000, 800 series, Hyper 2000, X-series batteries
Who the SolarFlow Suits
The SolarFlow makes most sense if you already own panels and a microinverterand want to stop giving your surplus away. Slot the hub into the existing DC run, add a battery, done — no other system lets you keep your current inverter. It's also the cheapest UK route into balcony battery storage at ~£650 for a complete starter kit.
It's a weaker choice if you're starting from scratch and want the least friction: the EcoFlow STREAM and Anker Solarbank are simpler to buy, simpler to set up, and better supported in the UK. And be honest about the maths — a battery extends payback on any balcony system, because you're saving the same ~25p/kWh either way and the battery only changes when you use it. Our battery storage guide covers when the numbers work and when they don't.
