Arc Detection and Prevention in a Power Generation System

A method comprising:

• measuring electrical noise in an electrical system to obtain a first measurement;
• sending an output power to a load;
• comparing the first measurement to a first threshold;
• responsive to determining that the first measurement is above the first threshold, reducing a voltage or a current of input power of the electrical system while maintaining at least some of the output power at an output of the electrical system;
• after the reducing of the voltage and the current, measuring electrical noise in the electrical system to obtain a second measurement;
• and
• determining, based on the second measurement, whether to set an alarm condition.

A power device comprising:

• a power circuit and a control circuit, wherein the control circuit is configured to cause the power circuit to:
• draw input power from a photovoltaic generator, wherein the input power comprises a voltage at a first voltage level and a current at a first current level;
• provide output power at an output of the power device;
• reduce the voltage or the current of the input power from the first voltage level to a second voltage level or from the first current level to a second current level that extinguishes an arc while maintaining at least some of the output power;
• and
• responsive to the arc extinguishing, increase the voltage of the input power.
