3.4 Features
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.
Power derating
Reasons to occur electric arcs.
• Damaged connectors in the PV or battery system.
• Wrong connected or broken cables.
• Aging connectors and cables.
Methods to detect electric arcs
• The inverter has an integrated AFCI function satises IEC63027.
• When the inverter detects an electric arc, users can nd the time of the fault and the detailed
phenomenon through the app.
• The inverter will shutdown for protection until the AFCI alarms are cleared. After clearing the
alarms, the inverter can automatically reconnect to the grid.
• Automatic reconnection: The alarm can be cleared automatically in 5 minutes if the
inverter triggers a fault for less than 5 times within 24 hours.
• Manual reconnection: The inverter will shutdown for protection after the 5th electric arc
fault within 24 hours. The inverter cannot work normally until the fault is solved. Please
refer to the SolarGo App User Manual for detailed operations.
