    Abstract: Various embodiments manage a fuel cell IT grid system to maintain fuel cell temperatures above a threshold temperature. The system may include power modules each including a fuel cell, DC/DC converters each connected to a power module, a DC power bus connected to the DC/DC, IT loads each connected to the DC power bus, a load balancing load connected to the DC power bus, and a control device connected to a first power module. The control device may determine whether a temperature of the first power module exceeds the temperature threshold, determine whether an electrical power output of the power modules exceeds an electrical power demand of the IT loads in response to the temperature exceeding the temperature threshold, and direct excess electrical power output to the load balancing load in response to the electrical power output exceeding the electrical power demand.

    Abstract: Systems, methods, and devices of the various embodiments enable parallel control of multiple uninterruptable power modules (“UPMs”) connecting multiple power sources to a bus in parallel. A UPM may be comprised of at least one controller coupled to at least one inverter, and the UPM may be configured to convert the DC voltage output from a DC source to an AC voltage, such as an AC voltage suitable for output to an AC bus. A UPM may receive a power sharing command and control its at least one inverter based at least in part on the received power sharing command to output a voltage to a bus.

    Abstract: A method of operating a power generator having a first electrical output electrically connected to a utility grid and a second electrical output electrically connected to a load includes detecting if the first electrical output of the power generator is electrically disconnected from the utility grid, and electrically connecting at least a neutral line of the first electrical output to ground in response to detecting that the first output is electrically disconnected from the utility grid.

    Abstract: A system and method of provided power to one or more electrical loads of an electrical load module is provided. The electrical load module includes an alternating current (AC) power input port, a direct current (DC) power input port, a power distribution device, a first power supply device, a second power supply device, and a first electrical load component. The power distribution device is electrically coupled to the AC power input port via a first connector and the DC power input port via a second connection. The first electrical load component is coupled to the first power supply device and the second power supply device. The first power supply device and the second power supply device are configured to provide power to the first electrical load component and a feed from an alternative power source system is directly connected to the DC power input port of the electrical load module.
