Abstract: A method for controlling a portable power system, comprising: using a processor, selecting an engine efficiency range for an engine of a generator set of the portable power system, the engine efficiency range corresponding to a power output range of the generator set and to a power demand range of a load coupled to the portable power system; while a power demand of the load is less than a power output of the generator set, storing excess energy from the generator set in a battery bank of the portable power system; while the power demand of the load is greater than the power output of the generator set, providing additional power to the load from the battery bank; when a first predetermined depth of discharge threshold is reached by the battery bank, increasing the power output of the generator set to allow the battery bank to recharge; and, when a predetermined state of charge threshold is reached by the battery bank, ceasing the power output of the generator set and providing power to the load from the batte
