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.
This paper presents a novel approach that simultaneously enables photovoltaic (PV) inversion and flexible arc suppression during single-phase grounding faults. Inverters compensate for ground currents through an arc-elimination function, while outputting a PV direct current (DC) power supply.
Under grid voltage sags, over current protection and exploiting the maximum capacity of the inverter are the two main goals of grid-connected PV inverters. To facilitate low-voltage ride-through (LVRT), it is imperative to ensure that inverter currents are sinusoidal and remain within permissible limits throughout the inverter operation.
Currently, research on fault current suppression in PV inverters is limited. Therefore, it is necessary to rely on arc-suppression devices to compensate for the fault current. Zhang et al. proposed a cascaded arc- suppression device that integrated flexible arc suppression by regulating zero-sequence currents.

Since the voltage amplitude of the arc suppression device is different during the normal operation and single line-to-ground fault, the problems of high cost and low module utilization rate
Grid-connected PV inverters (GCPI) are key components that enable photovoltaic (PV) power generation to interface with the grid. Their control performance directly influences system
Thus, once an arc-ground fault occurs in the distribution grid, the photovoltaic inverter automatically outputs a reverse inductive current to achieve arc suppression at the grounding point.
