14.9.9 Speed of the change output voltage/frequency according to the
battery voltage {1534}
This parameter allows to modify the speed of the change of the frequency (df/dt) activated by
{1549} and of the output voltage activated by {1548}. This is to best match the various brands of grid
inverters when it comes to AC-coupling. They don’t all have the same behaviour. There are 6 speed
possibilities:
1: 2x speed by default
0: speed by default
-1: 1/2 speed by default
-2: 1/4 speed by default
-3: 1/8 speed by default
-4: 1/16 speed by default
14.9.10 Standby and start (load detection) {1420}
14.9.10.1 Standby level {1187}
The standby function allows energy to be saved if there is no consumer present at the inverter output.
In this case, the inverter disconnects its output and periodically emits a load search pulse. If a
consumer is detected, it goes back into operational mode while measuring the power supplied and
returns to standby if the consumer is deactivated.
This configuration allows adjustment of the power output at which the inverter goes into standby
mode.
Proceed as follows to adjust this configuration:
Make sure that the inverter mode is active (no voltage present at the AC-In input). The input voltage
is 0 and the input relay is indicated as open in real time on the information screen.
Increase the standby level value {1187} to the maximum
Activate the smallest consumer that can be detected and ensure that all the others are deactivated.
Wait for the inverter to pass to standby, and the consumer then engages intermittently around once
a second.
Progressively reduce the standby level value {1187} until the consumer runs permanently. If the
consumer works for several seconds then stops, decrease the value of the standby level again.
An adjustment value between 0 and 100 is displayed. The value 100 represents the minimum
sensitivity (biggest consumer detected).
If you would like to deactivate the standby function, it is sufficient to adjust the
detection level to 0. In this case, the Xtender remains permanently activated if it is
working in inverter mode.
14.9.10.2 Duration between the standby pulses {1189}
This setting allows you to determine the interval between the standby pulses.
14.9.10.3 Number of standby periods {1188}
This setting determines the number of periods which are generated at the time of the standby burst.
Certain loads which are very difficult to detect may activate the inverter if the burst is
longer than the only period normally used.
In certain very particular cases, the standby is used to supply very small consumers.
Prolonging the search burst allows you to correctly supply these consumers without the
risk of loosing the supply during the waiting period between the pulses.
