the cable is a meter long lol! don't think volts drop is worth my hassle ;) Thank you for the great help though ... p.s work for a MCS accredited company and someone will be checking my work but was just a question.
I am currently installing a 18Kw 3 phase system.
The system has 3 strings of 25
Each panel has an output of 250W
The size of the AC cable on the spec is specified as 25mm from the AC isolator to the 3 Phase MCB.
If my calculations are correct..
18000/(√3x400) = 18000/1.732x400 = 18000/692.8...
