Introduction GT100E MS Combiner Box The GT100E MS combiner box, when installed with dual GT100Es, allows the GT100E Master/Slave configuration to maximize energy production during periods of low irradiance. A system would consist of two - 100kW inverters, one as the master and the other as a slave, and as a result, the GT100E system will run at greater than 94% efficiency above 20kW. Master/Slave Configuration The Master/Slave configuration would be implemented on the DC side of the invert

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

Introduction shutdown. The Master inverter will disable the Slave inverter and close the contactor in the GT100E MS Combiner Box. The Master inverter will go online. Fault Condition If the Master or Slave Inverter gets a fault or the status signal from either inverter is lost, the inverters will shutdown and restart as stand alone inverters. Mis-configuration of Units If the Master or Slave Inverter are mis-configured by the operator, the inverters run as stand alone inverters. Figure 1-1 C
