Modular power supply and storage products

A supervisory control system comprising:

• a communications bus;
• a power controller coupled to the communications bus and including programmable logic configured to monitor a power demand attached to a power supply system managed by the supervisory control system;
• a DC power controller coupled to the power controller via the communications bus and including programmable logic configured to manage the operation of an energy storage subsystem included in the supervisory control system, wherein the DC power controller includes programmable logic configured to operate the energy storage system in a voltage control mode;
• and
• a power generation controller coupled to the power controller via the communications bus and including programmable logic configured to manage power electronics and an power generation subsystem included in the supervisory control system, wherein the power generation controller is brought online by the power controller if the power controller detects that the power demand placed on the power supply system is more than a transient demand.

A method comprising:

• detecting the presence of a power demand on a modular power supply, the modular power supply including a power generation subsystem and energy storage subsystem;
• powering the power demand via the energy storage subsystem in response to detecting the presence of the power demand;
• enabling AC power generation after determining that the power demand is not a transient demand;
• monitoring a state of charge of the energy storage system;
• and
• targeting a net power flow upon determining that the state of charge of the energy storage system falls below a predetermined level.
