Sourcing and delivery under one contract

Important: the model is labelled “12 kW”, but its table specifies 10,000 W / 10,000 VA. Pending manufacturer confirmation, the tabulated 10 kW rating is used. The AP0 series uses an American split-phase configuration. Grid voltage, earthing, transformers and protection require an engineered design. The manufacturer lists AFCI and RSD. Listed standards are catalogue declarations, not Vezemo verification of certificates.
