The table shows the maximum line conductor length in relation to the
section of the conductor itself:
Line conductor cross sec-
tion (mm²)
Line conductor maximum length (m)
UNO-2.0 UNO-3.0 UNO-3.6 UNO-4.2
4 25 m 19 m 16 m 13 m
6 38 m 29 m 24 m 20 m
The values are calculated in nominal power conditions, considering:
- loss of power along the line no greater than 1%
- use of copper cable, with HEPR rubber insulation and positioned in open air
Load protection switch (AC disconnect switch)
To protect the inverter and the AC connection line, a device must be in-
stalled to protect against maximum current and leakage to ground, with
the following characteristics:
