Grid settings page includes the voltage and frequency protection points.
These protection points are linked to electricity regulations.
If there is no any special requirement, please do not change any grid settings.
5.3.7.3.2 Grid Settings
Inverter will measure the impedance between Array and PE before connect to grid.
If the impedance between Array and PE is lower than the value that set in Insulation
Settings, inverter will stop connecting to grid. There are 4 modes users can select in
Insulation settings: ON, Positive Ground, Negative Ground, or Disable. Installer can
also select different impedance according to the actual situation.
