The comparative voltage level at the switchback point is a pretty good indication of the battery condition, and I think that could be used to trigger an "I need a new battery" email message well ahead of an unexpected total fail shutdown.
I have a 20kw nat gas fired standby generator thats typically live in 5 seconds since the Mrs. has COPD, so I have never set that up here, but I believe you can find that in the Nut docs. Unless its been elided in the last 15 years. :( Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
