What is the Difference between 120V/230V Multiplus/Quattro?

I would like to install two multiplus or quattro units in parallel to get split phase 240V (120V line to neutral, 240V line to line. USA install). However, some units are labeled 120V, while others are labeled 230V. Does this impact which units can be used to produce the desired split phase 240V output?

Also, is it true that the 8kVA and up multis cannot be connected in parallel, while this limitation does not apply to any of the Quattros?

What are the largest two units that I could connect in parallel to achieve a 120V/240V?

Quattro = MP + an additional AC input though only one can be active at any time.

Quattros tend to have a greater availability of 48V systems for the 120V units.

120V: single phase 120VAC/60Hz units typical of N. America.

230V: single phase 230VAC/50Hz units typical of the EU.

Either may be used for split phase:

2X 120V units operating in parallel split phase OR

1X 230V unit configured for 240V/60Hz and coupled with an Autotransformer that provides 120/240VAC split phase.

I can't answer the last two questions.
