Battery Bank Capacity

For the Conext 80 600 CC in the operation manual under charger settings the default setting is 440ah. I have 12 390ah L16G-AC batteries. Right now the capacity is set at 1170ah. Am I correct in saying it needs to be set at 390ah?

    Assuming 24V, 3 strings of 4, 390Ah  6v  batteries, the total capacity would be 1170Ah, that would be what is used in the settings, not the individual capacity.

    since your capacity is so close to 1,000 amps, I would set the value to 1,000   It will make all the other settings that work off percent, so much easier.
