Hi,
I don't think that is a good idea.
But it depends for which controller do you asking for - you could look the similar post about that issue.

It is okay as long as you still connect your 0V wires to the L- terminals. (You don't want the only path back to the source to be via ground -- that is only intended for faults.)
