OPERATION
EXAMPLE OF NORMAL SYSTEM OPERATION
Upon initial application of AC voltage, the LED’s located on the front door will sequentially flash for
approximately 15 seconds. Once the system has finished initializing, the PV-15208 will remain in
standby until adequate PV voltage is available (amber LED is lit). 5 minutes after the PV start voltage
has been reached, the PV-15208 will synchronize to the utility grid and begin peak power tracking the
PV array. The time delay protects the inverter from excessive on/off cycling.
The PV-15208 will continue to process power until the AC output power approaches the operating
losses of the inverter for a period of 5 minutes. The time delay protects the inverter from excessive on/
off cycling.
SYSTEM OPERATING PARAMETERS
The PV-15208 contains a number of system operating parameters which may be field adjusted using an
optional graphical user interface program available first quarter, 2001 (contact Xantrex/Trace Tech-
nologies 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 and efficient operation of the PV-15208 connected
with any PV array configured for a 330-500 VDC peak power voltage point.
Below is a list of the PV-15208 operating parameters, showing valid ranges and the factory default
settings. Some field adjustable parameters are password protected and may only be changed by trained
service technicians. In particular are 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-15208 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-15208 from functioning.
