The computers have backup power (UPS), but it’s usually just enough to get everything shut down properly. As for the system itself, that’d be a negative. It’d take a helluva lot of batteries to pump out 480 volts at 200 plus amps!
Its not practically impossible to have a battery back up system for ROVs, just might be loads and loads of batteries. I am not so sure about 200A plus current draw, never worked on a system that draws that much. The thing is with the rig power plus a motor generator things are usually well covered.
