Description of System Operation
Overview
The PV100S is a fully automated
•Stable utility AC voltage and frequency as specified in Table
•PV voltage as specified in Table
•With the exception of the Matrix Test state, the ON/OFF switch, located on the front door of the PV100S 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.

Faults
Fault states are automatic from any state of operation. In the event of a fault condition, the PV100S 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
Once the cause of the fault has been identified and corrected, and it is determined to be safe to proceed, PV100S faults may be cleared from the UFCU keypad or via the remote GUI.
