The Balco 260 is an all-in-one balcony storage unit: the battery and inverter share the same body, which connects to the grid through the Schuko plug and stays within the feed-in limit set by your country. Under the main unit, up to five BC260 satellite batteries stack up, so capacity grows over time without buying a second inverter. Four independent solar inputs allow panels to face different sides of the balcony, so shade on one side doesn't penalize the others. Below five degrees the battery heats itself to keep charging even in winter.
Basic control - power on, charge status, grid feed-in - also works over direct Bluetooth from the phone, with no internet needed: useful if home Wi-Fi doesn't reach the balcony. The more advanced functions, like automatic optimization based on energy prices and sharing across multiple units, stay tied to the cloud, though. The system withstands rain and splashes and can stay mounted outdoors year-round, but it should be covered or moved during severe storms. During a grid outage it keeps delivering power only from its own output socket: it doesn't feed the home's electrical system.
It's designed for anyone who wants to start with a balcony and grow over time by adding satellite batteries, and for anyone looking for a system that can be controlled even offline. Installation requires drilling into the wall with anchors to secure the brackets, though: anyone renting needs the landlord's permission first, because it's not a system that simply hooks onto the railing.

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.
