Can I ask for some advice please , I am installing my Rosen Solar off grid system .
I have 4 x strings of 7 x 400 w panels into a combiner box , and have 2x Growatt 5k inverters which involves a 36 metre cable run .
I have 100M rolls of cable 1x black , 1x red to carry the power , according to various calculators the 4mm has not sufficient capacity .
So as I can utilise my cable and add another cable , 6mm to increase the capacity , giving a total of 10mm .
Is this a sound idea ?
is my logic applicable ?
many thanks ,
