Xantrex Technology PV100S-208 Shutdown, Fault, Manual Current, Matrix Test, Automatic Sleep Test

Operating States

Shutdown

The line interface controller is idle. The CCU2 monitors the status of the PV array and utility grid, waiting in standby until the PV array is available to produce power to the grid.

Fault

The PV100S has encountered a fault condition. When this happens, regardless of the PV100S state of operation, the PV100S will stop processing all power and execute an orderly system shutdown. A description of the fault and fault code will appear on the operator interface LCD. The Fault state may be cleared from the keypad once the cause of the fault has been corrected. See Chapter 4, “Troubleshooting” for a complete description of all fault codes.

Manual Current

This operating state is provided to evaluate the existing PV array V-I characteristics. The PV controller regulates a constant amount of PV current as commanded by the user from the operator interface keypad, up to the PV current limit of the PV100S. If the user commands more PV current than is available, the DC bus voltage will drop below the minimum bus voltage level and the PV100S will enter Shutdown mode.

Matrix Test

This operating state is provided to verify proper operation of the matrix and associated control electronics. There is no power transfer between the PV and utility in this mode. The ON/OFF switch must be in the OFF position for the PV100S to enter this state.

Automatic Sleep Test

Toward the end of every solar day, the PV100S automatically determines when to stop producing power dependent upon the output power of the inverter. As the net output power of the PV100S nears zero, a timer is started to allow the inverter to ride through any brief irradiance reductions.
