Export Power Limit Derating
When the meter detects that the export power is greater than the limit value on the
LCD, the inverter will reduce the output power within the specified range.
Power Factor Derating
When the power factor PF<1.0, the inverter will reduce the output power within a
specified range. The following figure shows the power factor derating curve.
