GeneralAdvancedMeter CTExportLimit Rate XXX.X%Set OKIf the local grid company requires to limit the output power from your inverter systems,we introduce the concept of Export Limit Rate.The ratio of your system output power divided by the rated power of the inverter is called Export Limited Rate.For example,if the local grid companyonly accepts 4kW from your 5kW system,then the Export Limit Rate of 5kW inverter should be 80%.
