Figure 9-1 Derating curve with DC input voltage
2.
When the grid Voltage is within 100%~110% of the rated output
voltage, the inverter output power may reach 100%. When the grid
voltage is lower than 100%, the inverter will limit the AC Output Current
and the output power will begin to derate, as shown in Figure 9-2.

3.
When the ambient temperature is higher than 42°C, the inverter output
power will begin to derate, as shown in Figure 9-3.
