Arild,
I think you are being overly optimistic about the sulfating problem.
A 4 volt difference in charging is over 10 percent of the overall
voltage. In 12 volt terms this is equivalent to charging a 12 volt
battery to about 12 volts instead of 13.2 volts, which should be
obvious is nearly dead as a door nail.
It is not clear if this is what the orginal poster had in mind, but
unless we are missing something here, the 32 volt alternator charger
is going to be of less than any use at all.
Regards,
