Amp current draw vs Amp hours etc.

[JasonJones]

Ok so I'm fairly confident my calculations are correct but I'm just looking for some concrete help here.

Let's say total current draw is 2,129a(3,300W x 8 / 12.4v)

Charging system will supply 1,360a(340x4)

This leaves 769a of current unnaccounted for to charge, and I have not a clue to calculate if at full tilt what impact it would have on the potential of the system.

Is an Ah literally ONE Ampere per hour(by definition it is). Therefor if I have 769 Ah of stored charge I will be fine and the system would not dip at all?

I apologize if anyone thinks this is very stupid, however, I couldn't really find a concrete answer on it through searching.

Thanks for anyone's help!
