Context
The AC power cables used for the inverter must be three-pole outdoor cables. For easier installation, use
flexible cables. The table lists the recommended specifications for cables and circuit breakers.

Table 2 – Recommended specifications for AC output cables
Note:
For safety reasons, make sure to use correctly sized cables, otherwise the current may cause
excessive heating or overloading, which could result in a fire.

Multi-core copper cables
The cross-section of the power line must be sized in order to
prevent unwanted disconnections of the inverter from the grid
due to high impedance of the cable connecting the inverter to the
point of supply. In addition, the AC cable must be correctly sized
to ensure that the loss of power on the cable is less than 1% of the
rated power and to ensure the proper functioning of the anti-
islanding protection. The cable length from the inverter to the
grid should not exceed 150 meters.
The figure below shows the relationship between the power loss
in the cable, its length and the cross-section area.
