5.2.9 Activating "Q on Demand
24/7"
Inverter Self-testing
If the Q on Demand 24/7 function is enabled,
the inverter self-test must be set to a time when
there is enough PV energy available to start the
inverters. If the PV energy is not high enough to
start the inverters, no self-test will take place.
Tip: If the Q on Demand 24/7 function is
enabled, set the time of the self-test so that the
inverter self-test occurs during the day (see
Section 5.2.14, page 43).
The Q on Demand 24/7 function enables the
inverter to provide reactive power both during and
outside feed-in operation. The setpoint of the reactive
power is determined by the settings in the grid code.
Procedure:
1. Open the LCS-Tool.
2. Select the desired SMA Inverter Manager from
the list.
3. Log in as an Installer.
4. Call up the menu Setup.
5. Select 5: Qext under Inverter Parameter in
the Basic Settings area. This setting generally
applies to the reactive power feed-in.
6. If required, you can have the Commissioning
Report displayed by selecting [Yes].
7. Select the night mode 0: Q@Night under
Inverter Parameter in the Basic Settings
area.
8. Select [Save] to save the changes.
