Master/Slave Operation States

If daily role reversal is on, then the configured slave is operational slave on odd days (January 1,3,5,...) and operational master on even days (January 2,4,6,...).

Master Unit

The GT100E Master inverter will control the GT100E MS Combiner Box via a control cable. The Master inverter will enable and disable the Slave inverter, and monitor the status of the Slave inverter through an interconnect cable. If the interconnect cable is disconnected, the master will open the combiner box and go online.

Slave Unit

The GT100E Slave inverter will monitor the status of the Master inverter through the interconnect cable. The inverter will be enabled from the Master inverter. If the interconnect cable is disconnected then the slave will go online.

Master/Slave Operation States

The Master/Slave operation states will follow the standard states specified by the GT100E Grid Tie Inverter Operation, Maintenance and Troubleshooting Manual (P/N 152365) with the following Master/Salve configuration state.

1.At Power up, the Master inverter will disable the Slave inverter, and close the contactor in the GT100E MS Combiner Box.

2.The Master inverter will go online through the normal operating States. The Slave inverter will remain disabled.

3.When the Master inverter's power level increases, and reaches the High Power Threshold (configurable parameter). The Master inverter will shutdown, open the contactor in the GT100E MSCombiner Box, and the Master will also enable the Slave inverter.

4.Both the Master and Slave Inverters will go to an online state.

5.End of the Day or Cloud Interaction - When the Master inverter's power level decreases, and reaches the Low Power Threshold and has maintained the power level for the Minimum Transition Seconds (configurable parameter). The Master and the Slave inverters will
