Volt-Watt P(V)
AU
The inverter changes the maximum input·output active power depending on system voltage. The
inverter responds in two ways depending on charging or discharging operation.
•
During charging operation
: If frequency decreases
below V
W2_CH
, it decreases input active power, and it
does not exceed the designated active power input
constraint W1 below V

Fixed Power factor
AU
The setting range for the fixed power factor mode is 0.8 to 1.0 and supplying and absorbing can be
set for reactive power. The default power factor is set to 1.0.
5
Fixed Q (Reactive power mode)
AU
The reactive power mode outputs reactive power in the fixed rate for apparent power. The minimum
setting range for the reactive power (vars) rate for apparent power is 60 % or higher from 60 %
absorption to 60 % supply, and the default reactive power is set to 0 %.
