Physical Characteristics
Main Inverter Enclosure
The PV100S Main Inverter Enclosure is
Power Distribution Panel
This panel contains many of the Electromechanical, protective, and control power components necessary to support the operation of the PV100S.
Converter Control Unit (CCU2)
The CCU2 is a Digital Signal Processor (DSP) based control board that performs numerous control and diagnostic functions associated with PV100S operation. Its most significant tasks are control of PV100S 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 Matrix
The power electronics converter is located at the top of the PV100S main inverter enclosure. The matrix is comprised of six switching transistors (IGBT’s), transistor gate drive electronics, a laminated power bus, DC capacitor bank, and an aluminum extrusion heatsink with a cooling fan. The fan is located above the matrix heatsink.
The PV array is tied logically to the matrix 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.
