Parameters
Parameters Min Max Unit Parameters
IINV Voltage Build
Up Time 0 9999 msec The sync of phase between inverter and grid
voltage will be checked after this time, since
“Initial voltage buildup” started(XP-TL does not
apply)
IINV PLL Stabiliza-
tion Time 0 9999 msec The phase between inverter and grid voltage
checked and for this time(XP-TL does not apply)
IINV PLL P Gain 0 999.99 - Grid voltage PLL’s P Gain used for “Initial voltage
buildup”(XP-TL does not apply)
IINV PLL I Gain 0 999.99 - Grid voltage PLL’s I Gain used for “Initial voltage
buildup”(XP-TL does not apply)
IINV Synchroniza-
tion Tolerance 1 20 degree This determines a tolerance limit when synchronize
the inverter and the grid voltage in „Initial voltage
buildup” state(XP-TL does not apply)
FRT Overcurrent
Protection Time 0 5000 msec The power generation is stopped for this param-
eter value after fault clear in FRT situation

8.7.1 Anti-Islanding Enable
With activation of Anti-Islanding function, XP-HV and XP-TL series will detect and disconnect itself from the
grid within a few second. If the Anti-Islanding function is not activated, XP-HV and XP-TL cannot disconnect
itself from the grid during grid failure, and generate power to load independently. For example, when inverter
infuse 500kW power to gird with 500kW load connected to PCC (Point of Common Coupling), inverter can
generate output voltage independently during grid failure, and operate itself with bearing 500kW load.
