Household inverter DC arc function

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 do photovoltaic inverters arc?

Photovoltaic inverters, as key devices, play an important role in converting DC energy to AC energy. However, arcing faults may occur due to aging, damage, or poor contact of components inside the inverter.

What are PV inverter arc faults?

Arc faults not only reduce the efficiency and reliability of the PV power generation system, but also may cause safety risks such as fire, which poses a threat to the safe and reliable operation of the PV system. Therefore, timely and accurate diagnosis of PV inverter arc faults is crucial.

What is integrated arc fault circuit interrupter (AFCI)?

When a PV inverter with an integrated arc-fault circuit interrupter (AFCI) is used, a serial electric arc in the PV array is detected soon enough and extinguished by an interruption of the current.

How do I Reset my inverter if it detects an arc?

If the inverter detects the arc five times, it will shut down completely. Clear the Alarm: Hold the Escape button for three seconds to reset the inverter. Enter the password 0010 or use the sequence DOWN DOWN UP DOWN. Select "ALARM MESSAGES" to view details of the incidents.

What are DC arc faults?

DC arc faults may occur due to aging, damage or poor contact of internal components of the inverter. Arc faults not only reduce the efficiency and reliability of the PV power generation system, but also may cause safety risks such as fire, which poses a threat to the safe and reliable operation of the PV system.
