Power Control Unit (PCU)
The PCU is a Digital Signal Processor (DSP) based control board that performs numerous control and
diagnostic functions associated with PV-100208 operation. Its most significant tasks are control of PV-
100208 electromechanical components and power electronics converters, signal conditioning for high
voltage signal inputs and communication with the operator interface panel and system sensors. The
PCU also contains the necessary DC power supplies to support its operation.
INTERCONNECTION STANDARDS COMPLIANCE
The PV-100208 has been tested and listed by Underwriters Laboratories to be in compliance with
UL1741 Static Inverters And Charge Controllers For Use In Photovoltaic Power Systems,
as well
as
IEEE-929-2000 Recommended Practice For Utility Interface Of Photovoltaic (PV) Systems.
IEEE-929-2000 provides guidance regarding equipment and functions necessary to ensure compatible
operation of photovoltaic systems which are connected in parallel with the electric utility. UL1741 is
the standard applied by Underwriters Laboratory to the PV-100208 to verify it meets the recommenda-
tions of IEEE-929-2000. Refer to both documents for details of these recommendations and test proce-
dures.
