Yes, the Solis is a Quick Mill Pegaso, only the housing and the knobs are slightly different...

Here are the technical specifications from the Solis manual:
Model no. 03055
Type 1150
Product name
Espresso machine
Voltage/frequency 220-240V~ / 50/60Hz
Power 900-1100 Watt
Dimensions approx. 32.0@28.0@40.0 cm (width@depth@height)
Weight approx. 13.2 kg
Water tank 1.8 litres
Max. Pump pressure 15 bar
Disk grinder 43 mm
Grinder settings 25
Portafilter 58 mm

The suspicion of Quick Mill hardens with the model number 03055 and the disc grinder as well as the 58mm sieve support. Also, the dimensions, water tank capacity and weight are exactly the same.

This is definitely a Quick Mille Pegaso!

Unfortunately, we don't have any information on this. You would have to ask Solis directly, as we have nothing to do with the production. :)
