It seems to me that a good way to avoid generator synch hassles would be to do the same thing that our Exide UPS does. Incoming power is rectified to keep the battery bank charged. It’s passed through to the equipment, until it drops out, when the battery banks take over. So what this is, is a UPS. But there is no interruption in the outgoing power. It is switched electronically, which happens in a fraction of a cycle.
COs have massive 48VDC batteries, so should they be used to full advantage? They can handle thousands of amps. It doesn’t have to be for long, just enough time to start the generators.
