Output losses of the Sunny Mini Central SMC 5000A
The following maximum cable lengths are possible for the different cable cross-
sections:
Cable cross-section 4.0 mm² 6.0 mm² 10.0 mm² 16.0 mm² 25.0 mm²
Max. cable length 12.4 m 18.6 m 31.1 m 49.7 m 77.7 m
With three-phase connection and symmetrical feeding, there is no load on the
neutral conductor, and the line losses are halved. Thus, the maximum possible
cable length is doubled.
Do not use cables where losses will exceed 1.0 %
