5.6 Connecting the AC Output Power Cable
Precautions
A three-phase AC switch should be installed on the AC side of the inverter. To
ensure that the inverter can safely disconnect itself from the power grid when an
exception occurs, select a proper overcurrent protection device in compliance with
local power distribution regulations.
WARNING
Do not connect loads between the inverter and the AC switch.
The inverter is integrated with a comprehensive residual current detection unit to
distinguish fault current from residual current. Upon detecting that the residual
current exceeds the threshold, the inverter immediately disconnects from the
power grid.
Cable Connection Precautions
NO TICE
● The cable outer diameter can be measured using the ruler sticker in the
maintenance compartment.
● Ensure that the cable jacket is in the maintenance compartment.
● Ensure that the AC output power cable is secured. Failing to do so may cause
the solar inverter to malfunction or damage to its terminal block by issues such
as overheating.
●
The ground point on the enclosure is preferred to connect to the PE cable for
the inverter.
●
The PE point in the maintenance compartment is used for connecting to the
PE cable included in the multi-core AC power cable.
●
There are two ground points on the chassis shell and you only need either of
them.
●
It is recommended that the PE cable of the inverter be connected to a nearby
ground point. For a system with multiple inverters connected in parallel,
connect the ground points of all inverters to ensure equipotential connections
to ground cables.
Cable Specifications
●
If you connect a ground cable to the ground point on the chassis shell, you
are advised to use a three-core (L1, L2, and L3) outdoor cable or three single-
core outdoor cables.
