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
multi-peak scanning
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.

Value Range
The value range for a 1000 V
inverter is [0.033, 1], and the
value range for 1100 V and
1500 V inverters is [0.033,
1.5].
Remarks
The scanning interval is set
by MPPT multi-peak
scanning interval.
This parameter is displayed
only when MPPT
multi-peak scanning is set
to Enable.
