Operation

Operating States

A state machine implemented within the CCU2 control software governs the operation of the PV225S with clearly defined transitions between its operating states. There are five steady-state operating states and numerous intermediate transition states.

•Power Tracking

•Transition

•Shutdown

•Fault

•Manual Current

•Matrix Test

•Automatic Sleep Test

Power Tracking

This is the standard operating state of the PV225S. The PV225S maximum power tracker will demand maximum power from the PV array, given sufficient PV irradiance.

The user should be aware of the following conditions governing PV225S state transitions:

•Qualified utility voltage must be present for all states of operation.

•Fault states are automatic from any state of operation. A fault will cause the PV225S to immediately stop processing all power. The fault condition will be reported to the operator interface LCD.

•Most PV225S faults are latching and must be cleared at the operator interface keypad before transitioning to another operating state.

•The ON/OFF switch, located on the front door of the PV225S, must be in the ON position for all operating states except Matrix Test, in which case it must be in the OFF position.

Transition

The intermediate transition states provide an orderly progression from one operating state to the next. The user has the ability to manually transition the PV225S between operating states via the operator interface keypad or remotely using the GUI software. Manual transitions are initiated by entering a “Goal State”, where the goal state is the desired operating state. Given all applicable system parameters are within acceptable limits, and the request is valid within the state machine, the PV225S will initiate the proper sequence of operations necessary to progress to the requested goal state. Refer to Figure 2-1 on page 2–3 for an illustration of valid state transitions.
