AC / DC Amps for AC In charge limit ?

ON the Color control settings ( or directly on the Veconfig / mppt settings) , we can limit the ac in current .

I just want to make sure i am not making a mistake.

200 ah at 48 v batteries. I want to limit the charge current to 10% to 15% of my Ah. So 200 ah x 12% = 24A. So i limit my mppt charger to 24 a . These are easy, they are DC Amp.

For the settings of my multi' gia ve config or ccgx color control, i can limit too my charger current limit (ac in). When i am on the color control page of themulti and can set the current limit ( 25 a on the picture), are these DC amps ',hence 25 a is ok, or are they AC amps ? If AC, then I should set a limit of : 25 a x 48 v = 1200 w ÷ 0,85 efficiency = 1411 w ÷ 230 v = 6.13 A AC . Is it this "6" i should enter as the limit ? I do not think so but prefer to check .

Thanks.

Thats about 5700w (230V×25A) dc, so that could indeed be about 100A dc value (at 57v )

Hoi,


This is AC (input)

This is DC ( system max. Charge amps)
