If you look at the schematics, the parallel cable connections directly
connect to the inverter output. The reason for the special cable set is
simply safety - the shrouded banana plugs prevent you from potentially
contacting the live output connections if you plug / unplug them.

A "suicide" cable with two regular 5-15 plugs will work properly, but
presents the safety hazard potential to have a live male plug. Many
people operate them this way to save a buck over buying the parallel
cable kit. Many smarter people order shrouded banana plugs and make
their own safety parallel cable set to save a buck.

Of course you still have the issue of 240V, since these are 120V
generators. You'd need a step-up transformer if you really needed 240V.

OK---I've got the part about phase syncronization, and understand that as a
practical
source of 240VAC there are some real problems, but I'm still not getting the
part about
needing a step-up transformer.

240VAC Single Phase is 2 120v legs and a common. Either leg to ground is
120v,
and leg to leg is 240v. We aren't talking 3 phase here.

SO why wouldn't two synchronized generators be a source of 240v single
phase?
