Description
To ensure device safety, the
inverter detects the insulation
resistance of the input side to the
ground when it starts a self-check.
If the detected value is less than
the preset value, the inverter does
not export power to the power
grid.
Description
When the inverter is used in
scenarios where PV strings are
obviously shaded, enable this
function. Then the inverter will
perform MPPT scanning at
regular intervals to locate the
maximum power.
Specifies the MPPT scan
interval.
RCD refers to the residual
current of the inverter to the
ground. To ensure device
security and personal safety,
RCD should comply with the
standard. If an AC switch with a
residual current detection
function is installed outside the
inverter, this function should be
enabled to reduce the residual
current generated during
inverter running, thereby
preventing the AC switch from
misoperations.
