Zendure AB3000X is an expansion battery for balcony storage, built to add capacity to an already installed SolarFlow 2400 AC system: on its own it isn't a standalone product. It mounts on the wall with the included brackets, so it can't tip over. It uses lithium iron phosphate cells and accepts a lot of charging and discharging power, so the pack fills up faster even when the system demands a lot. If it detects a short circuit or abnormal heating, an aerosol system triggers on its own and smothers the start of a fire without water or chemical powder.
It pairs with other identical batteries up to the full capacity the SolarFlow 2400 AC system can manage, adding them when needed instead of buying everything at once. It heats itself when the temperature drops, so it keeps charging even on a cold day.
It's built for anyone who has already chosen SolarFlow 2400 AC and wants to grow their balcony's energy reserve over time, not for anyone looking for a portable battery to use on its own.

The rest of the data comes from one page 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.
These numbers are calculated, not stated: they have no source to cite, they have a formula you can redo. The price used is the manufacturer's list price, which is stable and the same in every country — not a shop's price on the day.
Chosen by the declared use tier and footprint, not by price: we don't publish prices.
