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 inverter. The configuration would feed multiple PV arrays into the Master inverter until the irradiance increases and the power reaches the high power threshold of the Master inverter. Once the power reaches the Master inverter's high power threshold, the inverter would shutdown and disconnect from the additional arrays. The Slave inverter would then be enabled and both the Master and the Slave inverter would power up and come
The GT100E inverters will have the ability to run in the master/slave configuration or the ability to run independently
Difference between Configured Master/Slave and Operational
Master/Slave
Through the front panel or the Xantrex Solar GUI (Graphical User Interface), the user configures an inverter to be either configured master or configured slave. Next, the user sets daily role reversal on or off.
If daily role reversal is off, then the configured master is the operational master (operates as master) and the configured slave is the operational slave (operates as slave).
If daily role reversal is on, then the configured master is operational master on odd days (January 1,3,5,...) and operational slave on even days (January 2,4,6,...).
