● The minimum cable diameter must meet local standards.
● The factors that aect cable selection include the rated current, cable type, routing
mode, ambient temperature, and maximum expected line loss.
5.2 Connecting a PE Cable
Precautions
D ANGER
● Ensure that the PE cable is securely connected. Otherwise, electric shocks may
occur.
● Do not connect the neutral wire to the enclosure as a PE cable. Otherwise,
electric shocks may occur.
NO TE
● The PE point at the AC output port is used only as a PE equipotential point, and cannot
substitute for the PE point on the enclosure.
● It is recommended that silicone grease or paint be applied around the ground terminal
after the PE cable is connected.
● When the phase wire is short-circuited to the PE point, you can set the phase-to-PE
short-circuit protection switch on the app (choose Settings > Feature parameters >
Grounding abnormal shutdown). If the switch is disabled, only inverter alarm
detection is performed, and the inverter can connect to the power grid and generate
power normally.
Additional Information
The inverter provides the grounding detection function. This function is used to
check whether the inverter is properly grounded before the inverter starts, or
check whether the ground cable is disconnected when the inverter is running. This
function is only available under limited conditions. To ensure the safe operation of
the inverter, properly ground the inverter according to the connection
