There is an option to have three AC's on the XLR Thunderbolt and it is run by something called an "Energy Management System". Whatever that means?

An Energy Management System watched your load vs. your supplied power amps, whether it be shore power or generator. Some systems have a simple switch on the EMS panel where you select your input (20, 30, 50 amps). The EMS will shed load based on that and/or make sure things like 3 a/c units don't fire up at the same time causing too much of a load.
