The E3/DC S10 X is a three-phase storage system with usable capacity from 17.4 to 20.6 kWh and up to eight battery modules. Capacity can be increased within five years of installation by adding battery modules on site, with a paid system conversion, and it can be doubled with a second battery cabinet, which can be installed in a separate space.
When the grid fails, the system detects the outage and switches to stand-alone grid operation, in three phases. The backup power is designed mainly for lighting and comfort loads. The required motorized switch is installed at the factory, to order.
The warranty on the E3/DC system lasts ten years and remote maintenance is free of charge. The internet connection is used for remote maintenance and for checking the yield.

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.
