FCC Information to the User
This equipment has been tested and found to comply with the limits for a Class B digital device when
powered by a DC source, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and the receiver.
Connect the equipment to a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
Specification Compliance
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 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 GS8048A and
GS4048A inverters are tested to comply with the table below.

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 16.
