Power Limitation (Power Derating) - ABB PVS-100 Product Manual

2 - Characteristics
P
ower limitation (Power derating)
In order to allow inverter operation in safe thermal and electrical condi-
tions, the unit automatically reduces the value of the power fed into the
grid.
Power limiting may occur due to:
• Adverse environmental conditions (thermal derating)
• Percentage of output power (value set by the user)
• Grid voltage over frequency (mode set by user)
• Grid overvoltage U>10min Der. (enabling carried out by user)
• Anti-islanding
• Grid under voltage
• Input voltage values too high.
• High input current values.
