B-04: Set Battery Capacity
This setting controls battery charging amperages and other settings. The factory
setting for CAPACITY is 1600 amp hours for SC-80 MPPT and 3200 amp
hours for SC-160X MPPT.
At full output capacity a SC-80 MPPT can deliver 80 amps to a battery, this
amount of amperage (current) is equal to the C/10 (capacity divided by ten) rate
of a 1600 amp hour battery and, as such meets most manufacturers
recommendations for minimum PV charging capacity.
In applications with battery banks under 1600 amp hours it is recommended to
lower the Maximum Charge Rate setting from the default 80 amps to the C10
rate of the battery bank.
B-05: BAT. MAX Charge Amps
Use Constant B-05 to allow the installer to limit the maximum charge amps
allowed to the batteries. The factory setting is 80 amps (SC-80 MPPT) and 160
amps (SC-160X MPPT).
B-06: Set Absorption Volts
Use Constant B-06 to adjust the Absorption voltages. The default values are
based on the battery type and capacity selected. It is not advisable to change
default settings unless advised by the battery manufacturer or supplier.

FLOODED 13.9V~15.2V 14.6V
AGM 13.7V~15.1V 14.1V
GEL 13.6V~15.1V 14.1V
The above values are based on 12V system. The values x 2 are for 24V
system; the values x 3 are for 36V system and the values x 4 are for 48V
system.
OPTI-Solar SC MPPT Series will charge at the Absorption voltage and at the length
of time before switching to float mode.
