Specifications
These inverter/charger models have grid-interactive functions. All models are tested to comply with
certain limits for acceptable output voltage ranges, acceptable output frequency, total harmonic
distortion (THD) and anti-islanding performance when the inverter exports power to a utility source.
The OutBack inverter/charger models listed in this document are validated through compliance
testing. The following specifications refer to exporting power to a simulated utility source of less than
1% voltage total harmonic distortion (THD).

The THD of the root mean square (RMS) current is less than 5%.

The output of the FXR inverter exceeds the minimum power factor of 0.85 with a typical power factor of 0.96
or better.
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 22 on page 78.
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.
See the Grid Tied function on page 19 for more information.
