Reading this table

Rated AC is the continuous output

The nominal AC power from the datasheet, usually the number in the model name. Where only a maximum is published, that is shown instead.

Euro efficiency, not peak

The figure weighted across part loads, which sits below the peak efficiency a datasheet prints first.

kg per kW

Weight divided by rated power, so a 10 kW and a 3 kW unit can be compared for what they cost to mount.

A dash means no data

The manufacturer did not publish it. We never estimate a missing value.
