Operation

Description of System Operation

Overview

The PV225S is a fully automated grid-interactive photovoltaic inverter. System startup, system shutdown, PV power tracking, and fault detection scenarios are all governed and monitored by the CCU2 controller within the PV225S. Manual interaction or control of the inverter is necessary only in the event of a system fault. Additionally, the following conditions govern operation of the PV225S.

•Stable utility AC voltage and frequency as specified in Table A-3 must be present for all states of operation.

•PV voltage as specified in Table A-3 must be present.

•With the exception of the Matrix Test state, the ON/OFF switch, located on the front door of the PV225S main inverter enclosure, must be switched to the ON position for all operating states.

•The door of the main inverter enclosure must be closed with the door interlock switch in the engaged position.

•Both the AC and DC Disconnect switches must be in the ON or closed position.

•Fault conditions must not be present.

Faults

Fault states are automatic from any state of operation. In the event of a fault condition, the PV225S will immediately stop processing power and execute an immediate orderly shutdown, open both the main AC and DC contactors, and remain in a faulted state until the fault is remedied and cleared (manually or automatically).

Most faults are latching, and only those faults associated with grid disturbances are auto-clearing and thus enable the PV225S to restart after a 5 minute delay period. All fault conditions arising from within the PV225S are reported to the UFCU (Universal Frontpanel Control Unit). The 4-line LCD on the UFCU will display a hexadecimal value (fault code) and a brief text description of the fault.

Once the cause of the fault has been identified and corrected, and it is determined to be safe to proceed, PV225S faults may be cleared from the UFCU keypad or via the remote GUI.

See “Clearing Faults Manually” on page 4–3 for instructions on this procedure.
