Note 1:
When the rectifier is in the equalize state (charging the batteries), the output DC voltage should be 1.5 to
2 volts higher than the float voltage. For example: the voltages for floating and equalizing are listed below:
Float:  50.5 V DC
Equalize:  52 V DC 
(Refer to
 Note 2.)
Note 2:The Equalize voltage is 1.5 to 2 V higher when an EMF panel (Diode Drop) is utilized. When an EMF panel
is not provided, the Float and Equalize Voltage...
