OutBack GTFX and GVFX Certificate of Compliance to UL1741 Utility-Interactive Inverters

OutBack GTFX and GVFX inverters comply with UL1741 for utility-interactive inverters. The following specifications refer to exporting power to a simulated utility source of less than 1% voltage total harmonic distortion (THD).

•The output of the GTFX or GVFX exceeds the minimum power factor of 0.85 specified in UL1741 section 45.2.2. Typical power factor is 0.96 or better.

•The THD of the RMS (root/means/square) current is less than 5 percent of the fundamental under the conditions of UL1741 section 45.4.2. Individual odd harmonics do not exceed the limits specified in Table 45.1 of UL1741. Individual even harmonics do not exceed the limits specified in Table 45.2 of UL1741.

•The GTFX and GVFX inverters cease to export power to the simulated utility source under islanding conditions specified in section 46.3 of UL1741.

•The GTFX and GVFX inverters cease to export power to the simulated utility source after the output voltage and frequency of the simulated utility source are adjusted to each of the conditions specified in Table 46.1 of UL1741 within the time specified in that table. All production GTFX and GVFX inverters are tested to comply with the table below as specified in section 46.2 of UL1741.
