7.3.3 DC VOLTAGE REFERENCE
Group of parameters number [7]
Setting the reference value of the DC voltage.
MENU \ SETTINGS \ COMMANDS \ DC VOLTAGE REFERENCE
Name [ID]
Description
Def.
DC voltage reference
[293]
DC voltage reference. This value is applied if "None" is selected in V_DC
reference [502] (page 41)
625
V
Min. VDC [508] ÷ Max.
VDC [509]
DC voltage reference has to be higher than peak value of phase-to-phase
voltage.
V_DC reference [502]
Selection of parameter, which will represent the value of DC voltage
reference.
-
Signal
Selected parameter is automatically recalculated to the given range.
7.3.4 AC VOLTAGE REF.
Group of parameters number [872]
Setting the RMS value of output AC voltage reference in off-grid mode.
MENU \ SETTINGS \ COMMANDS \ AC VOLTAGE REF.
Name [ID]
Description
Def.
AC voltage ref.
[873]
The RMS value of the AC voltage reference in off-grid mode. This value is applied if
the signal Signal V_AC ref. [874] (page 41) is set to "none".
400 V
Min. V AC [877]
÷ Max. V AC
[876]
The peak value of the AC voltage reference (Urms x 1.4142) must always be lower than the
steady-state value of DC voltage to ensure proper operation of the inverter. If this value is
too high, warnings about controller saturation might be shown.
Signal
V_AC
ref. [874]
Selection of parameter which represents the reference phase-to-phase RMS value of
AC voltage.
-
Signal
Selected parameter is automatically recalculated to the given range.
7.3.5 POWER FACTOR REF.
Group of parameters number [160]
Grid-side power factor reference.
MENU \ SETTINGS \ COMMANDS \ POWER FACTOR REF.
Name [ID]
Description
Def.
Phi angle ref.
[294]
Phase difference reference between voltage and current on grid-side of the inverter.
This value is applied only if no signal is selected in Signal for Phi angle ref. [503]
(page 41).
0.0
°
-89.0 ° ÷ 89.0 °
By setting the non-zero phase angle it is possible to correct the capacitive or inductive
influence of other appliances connected to the inverter.
Signal for Phi
angle ref. [503]
Selection of parameter which represents the value of phase difference reference
between voltage and current.
-
Signal
Selected parameter is automatically recalculated to the given range.
Filter
of
Phi
angle [853]
Filter time constant of the signal of phase difference between the current and voltage
on the inverter side.
1.0
s
0.1 s ÷ 100.0 s
This parameter limits the rate of change of reactive power.
7.3.6 AC POWER REFERENCE
Group of parameters number [880]
Setting the active power reference, when the "active power control" is set by Control strategy [878] (page
44).
MENU \ SETTINGS \ COMMANDS \ AC POWER REFERENCE
Name [ID]
Description
Def.
AC power ref.
[881]
Setting the active power reference, when the "active power control" is set by Control
strategy [878] (page 44).
0.0
W
-9E6 W ÷ 9E6 W
Positive value is interpreted as energy consumption and negative as the energy
production.
Signal for P ref.
Selection of parameter which will be interpreted as the AC power reference.
