Looking for some advice please on cable lengths. Im worried my distance is too far.
Basically the distance of my panels to the inverters is 38m (125ft). Unfortunately the inverters are west of the string so either the plus or the minus have to be much longer than this again.13m (42ft). Also already on panels is 1.2 long on each panels with is adding a further 28.8m (95ft).
Should I be cutting the mc4's off the panels and putting my own on so they are much shorter? is there any reason I shouldnt do this?
Without cutting the cable on panels the yellow string's total length would be: 80m (262ft) and if I cut them it would be 55m (180ft)
Does it make any difference having the plus of minus as the longer one?
Image has 3 strings in series. the yellow im using in the above example. The are positioned orientated and grouped like to do minimise shading.
Im using 6mm2 (10awg) solar cable. The total voc of string is 450 and the max amps is 15a
thanks in advance for any advice
