How to prevent the arcing of the DC side of the inverter?
2.Solax’s solution In order to prevent the arcing of the DC side of the inverter from causing fires and other hazards, SolaX engineers have developed the integrated AFCI function, which detects the arcing of the DC side and cuts the circuit in time to protect the user and the electrical system.
Why are arc faults difficult to extinguish?
There is no natural zero−crossing in the DC current, which results in the relevant fault arcing being difficult to extinguish by itself [6, 7]. According to the relationship between arcs and PV inverters, arc faults can be categorized as series and parallel ones.
Does a PV inverter have an arc-fault circuit interrupter?
The inverter is equipped with an integrated photovoltaic (PV) arc-fault circuit interrupter as required for PV systems by National Electrical Code® ANSI/NFPA 70 (NEC).
Are DC arc faults dangerous?
Author to whom correspondence should be addressed. DC arc faults are dangerous to photovoltaic (PV) systems and can cause serious electric fire hazards and property damage. Because the PV inverter works in a high−frequency pulse width modulation (PWM) control mode, the arc fault detection is prone to nuisance tripping due to PV inverter noises.
