● In addition to this manual, the system operation or service
manual must include a battery maintance manual applicable to
the type of batteries used.
● 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.

and is identified by the symbol below:
