Data from official source
The Anker SOLIX BP7000 is the expansion module of a single system: it attaches to the Solarbank Max AC, up to five modules in a column. It isn't compatible with the expansion batteries of the other Solarbanks, and on its own it does nothing: conversion and feed-in remain the control unit's job.
The cells heat themselves, so charging doesn't stop below zero, and the body withstands rain and water jets: it's built to stay outdoors all year round. Each module adds 7 kWh of reserve.
It's for anyone who already has a Solarbank Max AC and finds that a day's sun isn't enough anymore: it isn't a starting point.

Which documents this page rests on
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.

- the manufacturer does not state the guaranteed total energy throughput, which for heavy users is often the limit that runs out first
- on nominal capacity: the manufacturer does not state the usable figure, so the real cost is higher

03 · Summary
Pros and cons
In favour
- The cells heat themselves: charging doesn't stop below zero.
- Up to five modules in a column under the same control unit: it grows as much as needed.
- It withstands rain and water jets: it stays outdoors all year round.
- Each module adds 7 kWh of reserve.
Worth knowing
- It only attaches to the Solarbank Max AC: it doesn't work with the other Solarbanks.
- It has no inverter or outlets of its own: without the control unit it's just a container of cells.
- It sits on the floor, with the base bracket sold separately.
