Most anything over 26-27 volts will make the 433AH not happy. Best
to use a DC-DC converter that puts out a true 24V. I've also just put
three silicon diodes in series on the +V power lead. Each diode drops
~~ .7 volts, so three of them would drop 28 volts down to 25.9 volts.
Kind of silly putting such a narrow voltage tolerance on this kind of
device (IMO). All of our remote sites, solar or AC powered are running
straight from the float voltage on a 24V battery array.
