through compliance testing and refer to exporting power to a simulated utility source of less than 1%
voltage total harmonic distortion (THD).
The inverter output exceeds the minimum power factor of 0.85 with a typical power factor of 0.96 or better.
The individual harmonics do not exceed the limits specified in Table 3 of IEEE 1547 Section 4.3.3.
The THD of the root mean square (RMS) current is less than 5%.
The inverter ceases to export power to the simulated utility source under islanding conditions specified in
IEEE 1547 Section 4.4.1.
The inverter also ceases to export power to the simulated utility source after the output voltage or
frequency of the simulated utility source are adjusted to each of the conditions specified in IEEE 1547
Section 4.2.3 Table 1 and Section 4.2.4 Table 2 within the times specified in those tables. All grid-interactive
FXR inverters are tested to comply with
Table 19

The reconnection delay has a default setting of 5 minutes. The grid-interactive default settings are
shown in the
Grid Interface Protection Menu
portion of Table 23.
The
Grid Interface Protection
settings are adjustable. However, this is only available to operators with
installer-level access. The reason for this limitation is that there are firm rules concerning the
acceptable voltage range, frequency range, clearance time during power loss, and reconnect delay
when exporting power back to the utility. The rules differ in different locations around the world,
although generally it is expected that the settings cannot be altered by the end user. For this reason,
the installer password must be changed from the default to get access to these settings.
Once this password has been changed, the
Grid Interface Protection
settings can be accessed by
using the installer password.
