Data from official source
Hub 2000 collects current from two strings of balcony solar panels and splits it in two directions: toward an external microinverter, which converts it for use in the home or for grid feed-in, and toward a satellite battery connected underneath the device, which stores it for when the sun isn't enough. On its own it stores no energy: both the microinverter and the battery (AB1000, AB2000, SuperBase V or Satellite Battery) are bought separately.
It mounts on a wall, connects to the panels with MC4 cables and to the battery with its dedicated cable, then leaves it to the Zendure app to decide how much energy goes to the microinverter and how much gets stored. It can't be used during a grid outage: it isn't a backup device, but a manager of the energy produced by the balcony during daylight hours.
It's built for anyone who already has panels and wants to stop feeding the surplus energy back to the grid for nothing; it answers the question of whether it's worth adding storage to your own balcony system, not the one about what stays on during a blackout.

Which documents this page rests on
The rest of the data comes from 2 pages on the manufacturer's site, cited row by row in the table above.
A manual or a datasheet counts as a source even when the original file is hosted elsewhere: what matters is the document, not the server. Where that happens, it is stated above.

03 · Summary
Pros and cons
In favour
- Two independent MPPT trackers for two panel strings, so one side in the shade doesn't hold back the other's output.
- It expands up to four AB2000 batteries in parallel, reaching 7.68 kWh on a single unit.
- IP65 rating: built to stay exposed on a balcony, not just in a storage room.
Worth knowing
- Neither the microinverter nor the battery is in the box: both have to be bought separately to make the device work.
- When power fails it turns off along with everything else: it doesn't keep anything on, not even long enough to close a fridge.
- If the chosen battery is a SuperBase V or a Satellite Battery, only one can be connected at a time: stacking multiple units only applies to AB1000 and AB2000 batteries. source
