5.4.1 Conditions for the AC connection
Cable Requirements
The grid connection is established using three conductors (L, N, and PE).
We recommend the following specifications for stranded copper wire. The AC
plug housing has the lettering of length for stripping cable..
Object Description Value
A External diameter 14 to 20mm
B Conductor cross-section 6 to 16 mm²
C Stripping length of the insulated conductors approx. 16 mm
D Stripping length of the outer sheath of cable approx. 46 mm
Larger cross-sections should be used for longer cables.
Cable design
The conductor cross-section should be dimensioned to avoid power loss in
cables exceeding 1% of rated output power.
The higher grid impedance of the AC cable makes it easier to disconnect from
the grid due to excessive voltage at the feed-in point.
The maximum cable lengths depend on the conductor cross-section as
follows:

8 mm² 15m 15m 11 m 9m
10 mm² 18m 18m 14 m 11m
The required conductor cross-section depends on the inverter rating, ambient
temperature, routing method, cable type, cable losses, applicable installation
requirements of the country of installation, etc.
