1. A hybrid energy system configured to carry a power load for a generator configured to output a first AC signal, the hybrid energy system comprising:
a battery bank comprising a plurality of batteries and configured to output a first DC signal;
a DC/DC converter, when operating in a first mode, is configured to receive and convert the first DC signal into a second DC signal, wherein the second DC signal is output to a DC bus;
an AC/DC converter configured to receive and convert the first AC signal from the generator into a third DC signal, wherein the second DC signal and the third DC signal are tied together on the DC bus;
a DC/AC converter configured to receive and convert the second DC signal from the DC bus into a second AC signal, wherein the second AC signal is output to an AC outlet interface;
a controller operable to control the DC/DC converter and to select a second mode for the DC/DC converter, wherein the DC/DC converter, when operating in the second mode, is configured to receive and convert the second DC signal from the DC bus into a fourth DC signal, wherein the fourth DC signal is output to the battery bank to recharge the battery bank, wherein the first mode is a battery discharge mode and the second mode is a battery recharge mode;
wherein the controller is configured to output a startup signal to the generator to start outputting the first AC signal when the controller selects the second mode for the DC/DC converter, wherein the controller is configured to control the operation of the generator such that the generator warms up and cools down before shutdown, and wherein the controller is configured to control the operation of the generator such that the generator ramps up its power output and ramps down its power output.
