Description

Power Limit

Soft limit

: Set the power feed into the utility grid according to local 

requirements and standards.

Hard limit

: The inverter and the utility grid will automatically 

disconnect when the power feeds into the grid excesses the required 
limit.

Set Power Limit

Set the power feed back into the utility grid according to the actual 
situation.

Set Modbus Addr

Set the actual Modbus address.

LVRT

With LVRT on, the inverter will stay connected with the utility grid 
when a short-term utility grid low voltage exception occurs.

HVRT

With HVRT on, the inverter will stay connected with the utility grid 
when a short-term utility grid high voltage exception occurs.

Grid Type

Set the grid type according to the actual grid type. Supported grid 
type: star grid and delta grid.

Set ARC

ARC is optional and off by default. Enable or disable ARC accordingly.

Fault Clear

Clear ARC alarm records.

Self Check

Check whether ARC can work normally.
