Controller Specification
The variable “n is adopted as a multiplying factor when calculating parameter voltages, the rule for
“n” is listed as: if battery system voltage is 12V, n=1; 24V, n=2; 36V, n=3; 48V, n=4.
For example, the equalize charge voltage for a 12V FLD (Flooded) battery bank is 14.8V*1=14.8V. The
equalizing charge voltage for a 24V FLD (Flooded) battery bank is 14.8V*2=29.6V.
