Notes from our research: Complete pre-built unit (panel in its own frame); panel make/model and electrical specs not published beyond 'photovoltaic cells manufactured in Spain'. Inverter conflict: the 340W datasheet (V2.0) cites type-test ref HOYMZ/03485/V1, which is a Hoymiles HMS-450-1T, but ENA entry MODUL/21440 describes a '340W Modular Solar Unit 400W inverter' and the product page says '400W inverter'; the two ENA refs (21168, 21440) may be two inverter variants, so the unit shipped may have an HMS-400-1T instead. Specs above are for the HMS-450-1T. Hoymiles HMS-1T uses Sub-1G radio needing a DTU gateway; Modular Solar mentions no monitoring, so monitoring left null. Product page says depth 200mm, datasheet 160mm; dimensions are for the whole unit, not the panel. Units can be daisy-chained (cables provided); cable length not stated.
