Can't find the manual from my old (1995) Trace DR1524 inverter/charger.
There are two settings: Equalize 1 and Equalize 2.
Does anyone remember what voltages these two settings might generate?
(Unit has a 35 amp charger)

    Does this link work for you?

    http://www.manualslib.com/manual/195381/Xantrex-Dr1512w.html?page=61#manual

    Should be to page 3-5 of the manual.

    The defaults appear to be:

    Bulk/Equalize 15.0 volts for #0 (Eq #1)
    Bulk/Equalize 15.5 volts for #1 (Eq #2)

    Thanks Bill. This online manual is more detailed than the printed one I have (had?). Of interest is the reduction in surge watts from 4400 to 3500 for the DR1524 model inverter. The section on charging and equalization is far more detailed than the older manual.
    I can't say enough good about this 20 year old unit which continues to operate flawlessly at my island summer camp.
