A good portable generator is more than $500, and if it's a wide-spread outage there's not enough portable generators to go around, and if there were, not enough people to set them and give them their fluids.
Doesn't take a "good" generator to maintain a -48V battery string. Drop it off. Plug it in. Start it up. Task some folks on an 8 hour loop to keep the tanks topped off.
Even battery-buffered overnight, solar PV works great if grid is down or even completely absent.
That's a clever idea but for the kind of equipment in question you'd need a dozen square yards of cells. That isn't available where most of these installations are. Though perhaps the utilities should have made an effort to site them where it could be. Regards, Bill Herrin -- William D.
