  • Page 3: Product Description

    IPM (Intelligent Power Module), insulated gate bi-polar transistors (IGBT’s) and gate drive circuits to allow interface of a photovoltaic array with a utility grid. The PV-100208 consists of an inverter bridge, photovoltaic controller, and associated control electronics. The PV- 100208 control software provides for complete overall system control with a variety of protection and safety features.

  • Page 4: Control Components

    DC bus and the utility grid. Operator Interface The operator interface is located on the front door of the PV-100208 main enclosure. It consists of an On/Off switch and a keypad with liquid crystal display for control and monitoring purposes. All inter- face components are NEMA-3R rated.

  • Page 5: Interconnection Standards Compliance

    PCU also contains the necessary DC power supplies to support its operation. INTERCONNECTION STANDARDS COMPLIANCE The PV-100208 has been tested and listed by Underwriters Laboratories to be in compliance with UL1741 Static Inverters And Charge Controllers For Use In Photovoltaic Power Systems, as well as IEEE-929-2000 Recommended Practice For Utility Interface Of Photovoltaic (PV) Systems.

  • Page 6: Specifications

    The PV-100208 has been designed for photovoltaic power systems, which operate within the following specifications. Application of the PV-100208 in a manner inconsistent with these specifications may cause damage to the PV-100208 and other system components, and is a violation of the terms of the warranty.

    PV-100208 and open the A/C contactor within the unit. The A/C contactor cannot be closed unless the switch is in the on position. The PV-100208 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-100208 and attempt to clear any system fault.

  • Page 8: Isolation Procedure

    SECTION 2 SAFETY PV-100208 will remain faulted until the ground fault is remedied and cleared at the operator interface (see section 5, troubleshooting). Over/Under Voltage and Frequency The over/under frequency and voltage detection setpoints have been chosen to be in compliance with IEEE-929 and UL1741.

  • Page 9: 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-100208 is a balanced, three phase, current sourcing inverter, and only operates with the presence of a stable utility voltage.

    National Electrical Code, ANSI/NFPA 70. The following wires for connecting the PV-100208 to external devices are not provided by Xantrex Technology: (See installation diagram on pages 3-5.) • Connect 3-Phase 208 VAC inverter output (AC Disconnect switch) to terminals of the 208 VAC inverter side of isolation transformer.

  • Page 16 • All PV-100208 operating parameters have been set at the factory, based upon prior experience with PV arrays. • It is recommended that the PV-100208 be watched during Wake-Up and Sleep Test. If the PV- 100208 cycles between operating and sleeping at either of these times, the condition setpoints are not set properly (refer to section 4 for detailed description of PV-100208 state transitions).

  • Page 17: Operation

    • Fault states are automatic from any state of operation. A fault will cause the PV-100208 to imme- diately 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-100208, must be switched to the on position for all operating states.

  • Page 18: Operation Features

    • The On/Off switch, located on the front door of the PV-100208, must be in the On position for all operating states except Matrix Test, in which case it must be in the Off position.

    DC Overvoltage Detection In the event of DC voltage greater than 600Vdc, the PV-100208 will execute an orderly shutdown and annunciate a fault to the operator interface. If DC voltage remains greater than 600Vdc, the PV-100208 may be irreparably damaged.

  • Page 24: Troubleshooting

    SECTION 5 TROUBLESHOOTING GENERAL In the event of a fault, the PV-100208 will annunciate the condition at the operator interface. The PV- 100208 will execute an orderly shutdown and remain faulted until the fault is cleared (manually or automatically). In general, the operator should respond to any PV-100208 fault as follows: 1.
  • Page 25 This fault is self-clearing. Once the utility frequency has recovered within the acceptable operating range, the PV-100208 will automatically clear this fault and resume normal operation after 5 minutes. If the fault will not clear, verify the adjustable setpoint is below the actual utility frequency. If the fault is sustained, contact your Xantrex Technology distributor for assistance or service.
  • Page 26 The PCU was not able to service the interrupt for approximately 1 second. Attempt to clear the fault and restart the PV-100208 by pressing the black reset button on the lower left corner of the PCU. If the fault is sustained, replacement or service of the PCU will be necessary.
  • Page 27 Make sure the fiber optics for the device and matrix in question are properly connected to the driver board. Similarly, make sure the fiber is properly connected at the PCU. Clear the fault and restart the PV-100208. If the fault is sustained, contact your Xantrex Technology distributor for assistance or service.
  • Page 28 SECTION 5 TROUBLESHOOTING Clear the fault and restart the PCU. If the fault is sustained contact your Xantrex Technology distributor for assistance or service. 0828 – PV Over-Current Fault (S) Current through the PV CT has exceeded the allowable limit.

  • Page 29: Preventative Maintenance

    Call your Xantrex Technology distributor for factory replacements or specifications. Electrical Connections Inspect the condition of all wiring within the PV-100208. Inspect all wire crimps and connec- tions for damage caused from high temperature. Check for corrosion. Replace any damaged wires.

  • Page 30: Isolation Procedure

    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-100208 will automati- cally begin power tracking, given the PV voltage is greater than the PV start voltage setpoint.
