Self-synchronizing devices, systems, and methods

A system for self-synchronizing inverters comprising:

• a plurality of self-synchronizing inverters connected in parallel to provide a combined synchronized output, each self-synchronizing inverter of the plurality of self-synchronizing inverters comprising:
• a direct current (DC) input to receive DC electricity from a DC electrical source;
• a converter circuit to convert the DC electricity at the DC input to alternating current (AC) electricity at an AC output;
• and
• a synchronization unit to operate with a non-linear characteristic;
• and
• a node to connect an AC output of a first self-synchronizing inverter of the plurality of self-synchronizing inverters to an AC output of a second self-synchronizing inverter of the plurality of self-synchronizing inverters, wherein the synchronization unit of the first self-synchronizing inverter receives a reference sine-wave AC signal from the synchronization unit of the second self-synchronizing inverter, and wherein the synchronization unit of the first self-synchronizing inverter synchronizes the AC output of the first self-synchronizing inverter with the AC output of the second self-synchronizing inverter based on the reference sine-wave AC signal to produce a combined synchronized AC power output at the node.
