•
Close the PV disconnect switch (if present).
•
Carefully measure VDC across TBDC+ and TBDC- (PV +/-) terminal block. The value should be
the same as at the PV array string disconnect device. It should also be positive.
•
Open the PV disconnect switch. The matrix capacitor bank voltage should slowly degrade to near
zero over a 5-minute period.
•
Open all PV string disconnect switches.
System Verification
•
Ensure the on/off switch is disabled.
•
Upon applying 208 VAC power to the PV-45208, observe the LCD display on the upper enclosure.
The LCD should display ‘init-FCU Version’, followed by the model number and software revision
before briefly going blank. The LCD may be difficult to see depending on external light conditions.
After approximately 15 seconds the panel should finish initialization. Upon completion, line 1
(system status) of the LCD should read ‘Shutdown’.
•
Remedy any faults reported. If the fault indicator does not change, the fault condition is still present
(see Section 5). Cycling the on/off switch will reset the PV-45208 and attempt to clear any system
faults. Once all faults are cleared, line 1 of the LCD will read ‘Shutdown’ indicating the PV-45208
is idle.
•
Close all PV array string disconnect switches (if present).
•
Close the main PV disconnect switch (if present).
•
Turn the on/off switch to the on position.
•
If the PV voltage is above the PV Start Voltage setpoint, and the PV Start Time is exceeded, the PV-
45208 should transition to “Power Tracking” (see Section 4, Operation).
•
Depending upon solar conditions, the PV-45208 may not operate at full power. If the PV array is
not experiencing full sun, the PV maximum power tracker will regulate the PV voltage to maintain
maximum PV power output. (See section 4 for further description of the peak power tracker).
•
The PV-45208 is now fully operational.
Fine Tuning
•
All PV-45208 operating parameters have been set at the factory, based upon prior experience with
various PV arrays. Contact your Xantrex Technology distributor for further information.
•
It is recommended that the PV-45208 be watched during Wake-Up and Sleep Test. If the PV-45208
cycles between operating and sleeping at either of these times, the operating setpoints may not be
set properly. (Refer to Section 4 for a detailed description of PV-45208 operating states). The PV-
45208 should not cycle if the setpoints are set properly.
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.
