Grid Voltage Derating Graph
When the volt-watt function is disabled and the grid voltage is within 100% to ~110% (V
nom
to ~1.1*V
nom
) 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 de-
rate, as shown in Figure 10-6.
