Introduction

Operation Features

The PV225S 225 kW Grid-Tied Photovoltaic Inverter is a UL 1741 listed, utility interactive, three-phase power conversion system for grid-connected photovoltaic arrays with a power rating of 225 kW. Designed to be easy to install and operate, the PV225S automates start-up, shutdown, and fault detection scenarios. With user-definable power tracking that matches the inverter to the array and adjustable delay periods, users are able to customize startup and shutdown sequences. Multiple PV225S inverters are easily paralleled for larger power installations.

The PV225S power conversion system consists of a pulse-width modulated (PWM) inverter, switch gear for isolation and protection of the connected AC and DC power sources, and a high efficiency custom Wye:Wye isolation transformer. Housed in a rugged NEMA-3R rated, powder-coated steel enclosure, the PV225S incorporates sophisticated Intellimod® (IPM) Insulated Gate Bipolar Transistors (IGBT’s) as the main power switching devices. An advanced, field-proven, Maximum Peak Power Tracker (MPPT) integrated within the PV225S control firmware ensures the optimum power throughput for harvesting energy from the photovoltaic array.

The advanced design of the PV225S includes an EMI output filter and the main AC contactor located electrically on the utility side of the isolation transformer. The location of the main AC contactor, and the ability to de-energize the isolation transformer during times of non-operation, greatly reduces the night-time tare losses consumed by an idle isolation transformer. An integrated soft-start circuit precludes nuisance utility-tie circuit breaker trips as the result of isolation transformer inrush current.

Additionally, the PV225S integrated controller contains self-protection features including over and under voltage and frequency safeguards. An integral anti-island protection scheme prevents the inverter from feeding power to the grid in the event of a utility outage.

The PV225S includes a local user interface comprised of an ON/OFF switch, keypad, and 4-line, 80 character LCD display. A user-friendly Graphic User Interface (GUI) provides a remote interface for operator interrogation of PV225S system status, control, metering/data logging and protective functions within the PV225S. The status, control, and logging features are also supported by the choice of three communication mediums, allowing the information to be accessed or commanded remotely.

Fixed Unity Power Factor Operation

The Xantrex PV Series of grid-tied inverters maintains unity power factor during operation. The control software constantly senses utility voltage, and constructs the output current waveform to match the utility voltage. The PV line of inverters is not capable of operation without the presence of normal utility voltage, nor is it capable of varying the output power factor off unity.
