Data from official source

Sheet curated by JouleSpecs — We check every spec sheet against the manufacturer's own documentation: each value carries its source and the date we read it. Published Sept. 22, 2026 · Last updated Sept. 22, 2026 · Data verified Sept. 22, 2026

Zendure SolarFlow 800 is the control unit of a modular balcony system: it has no battery of its own, but a microinverter with two panel inputs that manages solar production and feeds it into the home through a standard power outlet. Storage capacity is added separately, with AB1000 or AB2000 series batteries that stack up to six units.

Without a battery attached, the panels' energy that isn't used right away is lost: it's the battery that lets you shift consumption to the evening hours, and the system decides on its own when to charge or discharge it following your contract's time-of-use tariffs, without needing to be set every day. It connects to a standard home outlet, already compliant with grid certification.

It isn't a backup system: during a power outage it stops feeding current in, as required by European safety standards, and it doesn't keep the fridge or router running when the power goes out. It's controlled from the Zendure app over Wi-Fi or Bluetooth, and its resistance to dust and water splashes makes it suited to stay mounted outdoors, on the balcony, all year round.

03 · Summary

Pros and cons

In favour

It grows up to six stacked batteries, for a reserve well beyond that of a typical balcony system.
With an IP65 rating, it stays mounted on the balcony all year round without needing shelter from the rain.
It shifts the battery's charging and discharging to the cheapest hours on its own, without having to set it every day.
It connects to a standard home outlet already compliant with grid certification: no electrician needed for the connection.

Worth knowing

On its own it stores nothing: without at least one AB1000 or AB2000 battery added separately, energy that isn't used right away is lost. source
During a power outage it doesn't power anything: it stops feeding current in by safety rule, and it isn't a substitute for a backup system.
It only works with its own AB1000/AB2000 batteries: it doesn't connect to other Zendure devices like the Ace 1500 or the off-grid outlet strip. source
