Conext XW PRO 6848 6,800W 48V Installation

Grid Disconnect Settings
The Conext XW Pro will remain connected to the utility grid as long as voltage and
frequency are within the qualified range (i.e. less than the Over Voltage/Frequency limit
and higher than the Under Voltage/Frequency limit).
Grid voltage and frequency disconnect settings are defined in the table below, and take
effect only when the H/LVRT and H/LFRT curves are disabled.
Anti-Islanding
Disconnect
Slow Delay
The disconnection time delay for the grid voltage exceeding an over-
voltage voltage level, but lower than the fast disconnection level. The
default value for this setting is 0.5 seconds.
Anti-Islanding
Disconnect
Over
Frequency
The frequency above which the Conext XW Pro will stop export of power
and record an islanding fault. The default value for this setting is 60.5 Hz
(for 60Hz grid) and 50.5Hz (for 50Hz grid). The disconnect will occur if the
inverter is over frequency for 0.1 seconds.
Anti-Islanding
Disconnect
Under
Frequency
The frequency below which the Conext XW Pro will stop export of power
and record an islanding fault. The default value for this setting is 59.3 Hz
(for 60Hz grid) and 49.3Hz (for 50Hz grid). The disconnect will occur if the
inverter is under frequency for 0.1 seconds.
Anti-Islanding
Disconnect
Over Voltage
L-N Fast
The line-to-neutral voltage above which the Conext XW Pro will stop export
of power and record an islanding fault. The default value for this setting is
135 V.
Anti-Islanding
Disconnect
Over Voltage
L-N Slow
The line-to-neutral voltage above which the Conext XW Pro will stop export
of power and record an islanding fault. The default value for this setting is
132 V, and the disconnect will occur if the inverter is over frequency for 0.5
seconds.
Anti-Islanding
Disconnect
Over Voltage
L1-L2 Fast
The line-to-line voltage above which the Conext XW Pro will stop export of
power and record an islanding fault. The default value for this setting is 270
V.
Anti-Islanding
Disconnect
Over Voltage
L1-L2 Slow
The line-to-line voltage above which the Conext XW Pro will stop export of
power and record an islanding fault. The default value for this setting is 264
V, and the disconnect will occur if the inverter is over frequency for 0.5
seconds.
Anti-Islanding
Disconnect
Under
Voltage L-N
Fast
The line-to-neutral voltage below which the Conext XW Pro will stop export
of power and record an islanding fault. The default value for this setting is
65 V.
