Power Systems
Inverters intended for grid-interactive use in the United States and Canada must comply with the
established standards of UL 1741 and IEEE 1547 and 1547.1. These standards provide regulation for
acceptable output voltage ranges, acceptable output frequency, total harmonic distortion (THD) and
anti-islanding performance when the inverter is exporting power to a utility source.
The OutBack grid-interactive models are tested using the procedures listed in IEEE 1547.1 to the
standards listed in both UL 1741 and IEEE 1547. The following specifications have been validated
through compliance testing and refer to exporting power to a simulated utility source of less than
1% voltage total harmonic distortion (THD).
The output of the Radian series 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 Radian inverters cease to export power to the simulated utility source under islanding conditions
specified in IEEE 1547 Section 4.4.1.
The Radian inverters also cease 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 Radian inverters
manufactured for use in the United States and Canada are tested to comply with the table below.
