  Of course you can generate an out-of-phase signal. It's just an AC
generator like everything else. What happens is that if you are out of
sync with the other generators, there will be an energy loss because the
out-of-sync signal dampens the others. The worst possible scenario is,
of course, that your generator has a phase shift of 180 degrees compared
to the other generators, which causes maximal energy loss.
