
The country-specific power grid frequency should be taken into account at all
times.

The country-specific standards and directives should be taken into account at all

6.2.2 Grid Connection
AC terminal block is on the bottom of the inverter. AC connection is the
3-phase-5-wire grid connection (L1, L2, L3, N and PE).
AC Cable Requirements
Select AC cables according to the following factors:

Grid impedance corresponds to the specifications below to avoid accidental
short-circuit or output power derating.

Considering the voltage drop and other conditions, please enlarge the cable
dimension. Power loss of the cable should be less than 1% of the nominal power.

Withstand ambient temperature.

Cable layout (inside wall, underground, free air, etc.)

UV resistance and so on.
Connecting Inverter to Grid
High voltage inside the inverter!
Ensure all cables are voltage-free before electrical connection.
Do not connect the AC circuit breaker until all inverter electrical connections
are completed.
