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
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.
• When the inverter detects an electric arc, users can find the time of the fault and the detailed
phenomenon through the app.
• The alarm can be cleared automatically if the inverter triggers a fault for less than 5 times
within 24 hours. The inverter will shutdown for protection after the 5th electric arc fault. The
inverter cannot work normally until the fault is solved. Please refer to the PV Master App User
Manual for detailed operations.
RSD
A signal transmitter is integrated into the inverter to communicate with the external RSD. In the
event of an emergency, the external switch will be enabled to stop the receiver, then disconnect
the PV modules.
