Necessity for DC arc detection and interrupting
What is arc?
As a discharge phenomenon that occurs in a circuit in which direct current flows, the types of arcs include series arc, parallel arc, and partial disconnection arc.
When PV facilities are exposed to moisture, salt, and yellow dust for a long period of time, the insulation failure of DC power lines progresses, resulting in DC arcs.

01
Electrical fire accident prevention
DC arcs occur widely and can cause serious fire accidents if not detected promptly in the beginning, so technology to detect and interrupt them in the early stages is very necessary
02
Securing stability of power supply
Preventing fire accidents in PV modules and combiner box in advance enables stable operation of the PV system and minimizes power generation down time
03
Securing profitability
Securing economic feasibility by minimizing power loss by preventing malfunction of arc detection due to noise from external electronic devices such as inverters, which is a problem of existing technology
G2POWER’s PV generation system is an optimized solution for power generation efficiency by detecting DC arcs generated from
solar PV lines to prevent fire accidents and malfunctions to raise the reliability of PV system operation.
