Preliminary Recommended Cable Size
⚠️ The calculated design current exceeds the typical
current-carrying capability used here for 6 mm² cable.
Consider restructuring the PV array, increasing conductor
size, or both. If changing to series, check the inverter/
MPPT maximum PV voltage.
Important:
This calculator provides a preliminary cable-size selection
based on current. Actual cable sizing must also consider cable
length, voltage drop, ambient temperature, installation method,
cable grouping, conductor material, insulation rating and
applicable electrical standards.
PV reminder:
6 mm² is common for solar module cables, but it is not a universal
requirement for every solar installation.
