10.3.4 Grid Voltage Derating Graph
When the grid voltage is within 100%~110% (Un ~ 1.1*Un) of the Rated
Output Voltage, the inverter output power (Pn) may reach 100%. When
the grid voltage is lower than the Rated Output Voltage, the inverter will
limit the AC Output Current and the output power (Pn) will begin to
derate, as shown in Figure 10-4.
