Physical Characteristics

Main Inverter Enclosure

The PV225S Main Inverter Enclosure is NEMA-3R rated and contains the power distribution panel, the converter control unit (CCU2), and the power electronics matrices. Also found within the Main Inverter Enclosure are some of the system protection devices (such as the sense and control power fuses).

Power Distribution Panel

This panel contains many of the Electromechanical, protective, and control power components necessary to support the operation of the PV225S.

Converter Control Unit (CCU2)

The CCU2 is a Digital Signal Processor (DSP) based control board that performs numerous control and diagnostic functions associated with PV225S operation. Its most significant tasks are control of PV225S electromechanical components and power electronics converters, signal conditioning for high voltage signal inputs and communication with the Universal Front Panel Control Unit, and system sensors. The CCU2 also contains the necessary DC power supplies to support its operation.

Power Electronics Matrices

The power electronics converters are located at the top of the PV225S main inverter enclosure. Both the left and right matrices are comprised of six switching transistors (IGBTs), transistor gate drive electronics, a laminated power bus, DC capacitor bank, and an aluminum extrusion heatsink with a cooling fan. The fans are located above each matrix heatsink.

The PV array is tied logically to the matrices DC bus within the DC interface enclosure. The embedded CCU2 control unit manages the transfer of power between the DC bus and the utility grid by sending digitized gating signals to the IGBTs for producing a high-fidelity, sinusoidal output.

Inductor Enclosure

The Inductor Enclosure is NEMA-3R rated. It contains the necessary filter components to ensure the PV225S line current meets IEEE-519 (1992, Standard Practices and Requirements for Harmonic Control in Electrical Power Systems) and UL 1741 (2001, Static Inverters and Converters for use in Independent Power Systems) harmonic distortion requirements. Mounted on both the right and left side of the lower enclosure are inductor fans to allow cooling of the line filter components within. This enclosure also serves as the mounting base for the PV225S Main Enclosure.
