The Anker SOLIX Solarbank 3 E2700 Pro is a balcony storage unit that combines the battery, the inverter and the panel input point in a single body, to reduce cabling and simplify installation. It has four independent MPPT inputs for solar panels and a separate input to charge from the grid too, besides the sun. It grows with additional batteries when the starting capacity isn't enough anymore.
It returns energy into the home through its outlet connected to the grid, within the limit allowed by balcony solar regulations. It also has a separate outlet that keeps supplying power when the grid goes down: it powers whatever is plugged into it, not the home's circuits. It also takes advantage of changes in energy prices, when the utility makes them known: it charges from the grid during the cheapest hours or when the price drops below zero, and returns stored energy when it costs more.
The cable to connect it to a home outlet is included in the box, with the standard Schuko plug used across most of the continent. It withstands rain and splashes and can stay mounted outdoors, on a balcony or on a wall. It's designed for anyone who already has outdoor space with a bit of sun and wants to store excess energy instead of returning it to the grid for almost nothing; anyone looking for a reserve for power outages at home needs a different system, with a dedicated emergency outlet.

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.
