  • Page 3: Product Description

    The Trace Technologies Model PV-15208 is a 15KW Grid Tied Photovoltaic Inverter. It utilizes ad- vanced power electronics to allow interface of a photovoltaic array with a utility grid. The PV-15208 is a highly integrated assembly, consisting of an inverter bridge and associated control electronics all on a single board.

  • Page 4: Interconnection Standards Compliance

    Integrated Bus Board The PV-15208 design makes use of a fully integrated bus board as shown in Figure 1-2. The bus board assembly is mounted to an aluminum extrusion heat sink, which mounts through an opening in the back of the enclosure.

  • Page 5: Specifications

    The PV-15208 has been designed for photovoltaic power systems, which operate within the following specifications. Application of the PV-15208 in a manner inconsistent with these specifications may cause damage to the PV-15208 and other system components, and is a violation of the terms of the warranty.

    PV-15208 and open the main contactor within the unit. The PV-15208 is prevented from being restarted until the on/off switch is turned back to the on position. Cycling the on/off switch will reset the PV-15208 and attempt to clear any system fault.

  • Page 7: Isolation Procedure

    7, system schematic for further detail). Upon detection of 1.5 amps of ground fault current, the PV-15208 executes an orderly shutdown, and annunciates a ground fault at the operator interface. The PV-15208 will remain faulted until the ground fault is remedied and cleared at the operator interface (see section 5, troubleshooting).

  • Page 8: Installation And Initial Turn-On

    If a WYE wound transformer is used to interface with the utility, it is not necessary to connect the neutral (X0) to ground. The PV-15208 is a balanced, three phase, current sourcing inverter, and only operates with the presence of a stable utility voltage.

    PV-15208. Lag bolts should be horizontally level with each other. Leave a minimum of 1” of bolt protruding from the wall. 3. Place the PV-15208 bottom mounting ears, shown in Figure 3-1 and Figure 3-2 onto installed lag bolts. (See following page.) 4.

    WYE and the PV array is grounded, the neutral must be left floating. Ground loops will exist when the inverter starts switching, which will cause the inverter to shut down due to phase over-currents and may result in damage to the PV-15208. Also, insure that this neutral is not bonded to the isolation transformer frame.

    • Carefully measure VDC across TB1-1 and TB1-2 (PV +/-) DC TERMINAL terminal block. The value should be the same as at the PV PV-15208 Photovoltaic Inverter DOCUMENT: 150919 Operation and Maintenance Manual Copyright 2000, Xantrex Technologies Inc./Trace Technologies Corp.
  • Page 14 15208 should transition to “Power Tracking” (see Section 4, Operation). • Depending upon solar conditions, the PV-15208 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.

  • Page 15: Operation

    • Fault states are automatic from any state of operation. A fault will cause the PV-15208 to immedi- ately stop processing all power. The fault condition will be reported to the operator interface. • The on/off switch, located on the front door of the PV-15208, must be switched to the on position for all operating states.

    • Line 2: System Status - The current operating state of the inverter. • Line 3: Inverter Output Power or Fault Description - During normal operation, this line will report the inverter real time output power. If the PV-15208 is faulted, this line will report a descrip- tion of the fault condition.

  • Page 17: Example Of Normal System Operation

    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.

  • Page 19: Troubleshooting General

    SECTION 5 TROUBLESHOOTING GENERAL In the event of a fault, the PV-15208 will annunciate the condition at the operator interface. The PV- 15208 will execute an orderly shutdown and remain faulted until the fault is cleared (manually or auto- matically).

    The IPM module has detected a short circuit/over current condition, or low supply voltage. Possible causes: • Short circuit in output AC line. • Low supply voltage to IPM control circuit. • Shorted isolation transformer.

    Accumulation of dirt and debris on the aluminum extrusion heatsink and fan shroud will de- crease the ability to transfer heat, which can cause the PV-15208 to shutdown on over-tempera- ture alarms. Inspect the aluminum extrusion heatsink and fan shroud for accumulation of dirt.

    5. Turn the on/off switch to the on position. After a 15 second initialization period and a 5 minute wake up period, the PV-15208 will automatically begin power tracking, given the PV voltage is greater than the PV start voltage setpoint.
