Control Components - Xantrex PV-100208 Operation And Maintenance Manual

SECTION 1
PRODUCT DESCRIPTION
AC Interface Enclosure
This enclosure is NEMA-3R rated. The AC Interface serves as the connection between the isolation
transformer/utility and the PV-100208. This enclosure is where the AC line fuses and AC disconnect
switch reside. For specific control components see Drawing No. 151703 in Section 7 (Appendix).
DC Interface Enclosure
This enclosure is NEMA-3R rated. The DC Interface serves as the connection interface between the PV
array and the PV-100208. This enclosure is where the DC disconnect switch and DC contactor reside.
For specific control components see Drawing No. 151704 in Section 7 (Appendix).
The fuses within the PV-100208 are intended for protecting the PV-100208 control
circuitry only. They are not intended to provide protection for the PV array or external
cabling.
Power Electronics Matrix
The power electronics converter is located at the top of the PV-100208 Main Enclosure. The matrix is
comprised of switching transistors (IGBTs), transistor gate drive electronics, a laminated power bus,
DC capacitor bank, and an aluminum extrusion heat sink with a cooling fan. The fan is located above
the matrix heatsink.
The PV array is tied logically to the matrix DC bus via the DC interface enclosure. The embedded
control unit manages the transfer of power between the 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. Refer to Section 4 for detailed operation instructions.
Inductor Enclosure
This enclosure is NEMA-3R rated. It contains the necessary filter components to insure the PV-100208
line currents and voltages meet IEEE-519 and UL1741 harmonic distortion requirements. Mounted on
the right side of the lower enclosure is an inductor fan to allow cooling of the line filter components
within. This enclosure also serves as the mounting base for the PV-100208 main enclosure.

CONTROL COMPONENTS

The following assemblies are contained within the PV-100208 main enclosure as shown in Figure 1-2
(see Appendix in Section 7).
Power Distribution Panel
This panel contains many of the Electro-mechanical, protective, and control power components neces-
sary to support the operation of the PV-100208.
