● Use flexible multistranded copper cable for the battery and PV
connections.
The maximum diameter of the individual strands is
0,4mm/0,125mm² (0.016 inch/AWG26).
A 25mm² cable, for example, should have at least 196 strands (class 5 or
higher stranding according to VDE 0295, IEC 60228 and BS6360).
An AWG2 gauge cable should have at least 259/26 stranding (259 strands
of AWG26).
Maximum operating temperature: ≥ 90°C.
Example of suitable cable: class 5 "Tri-rated" cable (it has three approvals:
American (UL), Canadian (CSA) and British (BS))
In case of thicker strands the contact area will be too small and the
resulting high contact resistance will cause severe overheating,
eventually resulting in fire.
● Maximum current through a MC4 terminal: 30A
