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

To avoid risks of electrical shock, all wiring operations must be carried out with the disconnect
switch downstream of the inverter (grid side) off.
Be careful not to invert any phase with neutral!
High leakage current. Grounding is essential before connection to the power supply network.

haracteristics and sizing of the line cable
The cross-section of the AC line conductor must be sized in order to pre-
vent unwanted disconnections of the inverter from the grid due to high
impedance of the line that connects the inverter to the power supply; If
the impedance is too high it causes an increase in the AC voltage that,
on reaching the limit set by the standards in the country of installation,
causes the inverter to switch off.
