For the battery connection 3 groups of cables are needed, one for each polarity plus the central point (N)
(2)
Suggested cables for centralized battery configuration ( single battery )
(3)
Suggested cables for distributed battery configuration ( one battery for each power module )
The data detailed in the table above are indicative only. In designing the cables the rated
current carrying capacities given by the CEI-UNEL35024/1 table have been taken into account,
related to copper cables with PVC insulation sheath, with a maximum temperature of 70° C,
without applying any de-rating factor
. The given cross sections do not take into account the
overload currents allowed by each line, which are detailed in the product Technical
Specification. In case of different installation methods or operating temperatures higher than 70°
C, apply the corrective factor according to the standards in force in the country of installation.
