I was concerned about overvoltage when we got ours. The specs
indicate a range of voltages that are accepted with the max up
around 15V. Since this unit is made to be installed in RVs and
vans etc, it is designed to handle varying voltages during charging,
etc. If my battery bank needed equilization, I'd make sure it
was disconnected.

It'll run on clean 12.3 volts +-5%, but high voltages will burn out
the flourescent tube system which lights the screen, because there's a
stepup transformer for it which overheats at high voltages.

Indeed. Always use a 'whatever in' to 12V converter. I was involved on a
ship where 12 professional LCD touchscreens were installed. They were
rated
for 24V and directly connected to the 24V power system (=batteries).
Within
a few weeks, all monitor backlights failed. They couldn't stand the
voltage
of a full battery (27-28V).
