Figure 23 – Do not connect loads between the inverter and circuit breaker
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 metres.
The figure below shows the relationship between the power loss in the cable, its length
and the cross-section area.

The
3PH 10KTL-15KTL-V2
inverters are three-phase output inverters that comply fully with the local grid
connection requirements and safety standards.
