OPERATION

SYSTEM OPERATING PARAMETERS

The PV-45208 contains a number of system operating parameters which may be field adjusted using an
optional graphical user interface program (contact Xantrex Technology for further information). All
operating parameters have been set at the factory during system test based upon prior experience with
various PV arrays, or to be in compliance with UL1741. In general, the factory default settings allow
for stable, efficient operation of the PV-45208 connected with any PV array configured for a 330-600 VDC
peak power voltage point.
On the following page is a list of the PV-45208 operating parameters, showing valid ranges and the
factory default settings. Many of these parameters are specific to domestic or European operation.
Changing parameters not applicable to the region of operation will not affect inverter performance.
Some field adjustable parameters are password protected and may only be changed by trained service
technicians, specifically parameters relating to utility protection setpoints. These have been set in the
factory to the limits mandated by UL1741. Any changes to these setpoints should be agreed upon by
the local utility and the equipment owner. The ability to adjust the voltage and frequency setpoints
across the actual utility voltage and frequency has been provided as a simulation tool to verify the PV-
45208 accurately detects and responds to a utility excursion. This test should only be performed by a
trained service technician. It is possible to adjust the setpoints in a manner that will prevent the PV-
45208 from functioning.
