Modular microgrid systems and methods

A core module of a microgrid comprising:

• a charge controller to regulate direct current (DC) electricity to provide regulated DC electricity;
• an inverter to convert the regulated DC electricity from the charge controller to provide, to the microgrid, alternating current (AC) electricity;
• and
• synchronization circuitry to synchronize the inverter, according to a reference signal, to cause the inverter to provide the AC electricity as synchronized AC electricity, wherein the synchronization circuit includes non-linear circuitry to operate with a non-linear characteristic.

A microgrid comprising:

• an energy source to provide direct current (DC) electricity;
• a charge controller to regulate the DC electricity to provide regulated DC electricity;
• an inverter to convert the regulated DC electricity from the charge controller to provide alternating current (AC) electricity for the microgrid;
• and
• a synchronization circuit to synchronize the inverter, based on a reference signal, to deliver the AC electricity as synchronized AC electricity, wherein the synchronization circuit includes a non-linear circuit.
