Power derating
For a safe operation, the inverter will automatically reduce the output power when the operating
environment is not ideal.
The following are the factors that may occur power derating. Please try to avoid them during usage.
•
Unfavorable environmental conditions, e.g., direct sunlight, high temperature, etc.
•
Inverter's output power percentage has been set.
•
Over-frequency derating.
•
Higher input voltage value.
•
Higher input current value.
AFCI
Reason to occur electric arcs:
•
Poor contact of connectors in PV system.
•
Wrong connected or broken cables.
•
Aging connectors and cables.
Method to detect electric arcs:
•
The inverter has integrated AFCI function and met the IEC 63027 standard.
•
When the inverter detects an electric arc, users can find the time of the fault and the detailed
phenomenon through the app.
•
The inverter locks for protection after the 5th electric arc alarm. After the alarm is cleared, the
inverter will automatically reconnect to the grid for operation.
•
Automatic reconnection: If the inverter triggers AFCI alarms less than 5 times within 24 hours,
each alarm will be automatically cleared after 5 minutes, and the inverter will reconnect to the
grid for operation;
•
Manual reconnection: If the inverter triggers the 5th AFCI alarm within 24 hours, the alarm
needs to be manually cleared before the inverter reconnect to the grid for operation.
Please refer to the WE Mate App User Manual for detailed operation.
