Description
Set this parameter based on the grid code of the country or region
where the inverter is used and the inverter application scenario.
Set the working mode of the inverter based on the grounding
status at DC side and the connection to the power grid.
Description
To ensure device safety, the inverter detects the insulation
resistance of the input side with respect to ground when it starts a
self-check. If the detected value is less than the preset value, the
inverter does not connect to the grid.
