Description of the PV100S
The PV100S 100 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 100 kW. Designed to be easy to install and operate,
the PV100S 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 start up and shut down sequences.
Multiple PV100S inverters are easily paralleled for larger power installations.
The PV100S 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 custom Wye/Wye isolation transformer. Housed in a
rugged NEMA 3R rated, powder-coated steel enclosure, the PV100S incorporates
sophisticated Intellimod

(IPM) Insulated Gate Bipolar Transistors (IGBTs) as
the main power switching devices. An advanced, field-proven, Maximum Peak
Power Tracker (MPPT) integrated within the PV100S control firmware ensures
the optimum power throughput for harvesting energy from the photovoltaic array.
The advanced design of the PV100S 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 PV100S 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 PV100S includes a local user interface
comprised of an O
N /O FF switch, keypad, and 4-line, 80 character LCD display. A
user-friendly, Graphic User Interface (GUI) provides a remote interface for
operator interrogation of PV100S system status, control, metering/data logging
and protective functions within the PV100S. The status, control, and logging
features are also supported by the data modem (included) and can be accessed
remotely.
The PV100S comes in two modules comprised of six enclosures to house the
electronics described above. The first module includes the Main Inverter
Enclosure, Inductor Enclosure, DC Interface Enclosure, and Communications
Enclosure. The second module includes the Transformer Enclosure and AC
Interface Enclosure. These components are identified in Figure 1-1 on page 1–3.
Figure 1-1 also shows the dimensions and locations of the various enclosures that
comprise the PV100S.
