FAQs 6

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).

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.

Do PV systems need arc-fault circuit protection?

These requirements apply to newly installed PV systems with a maximum voltage of 80 volts or greater. Such PV systems must be equipped with direct current (DC) arc-fault circuit protection. DC arc-fault circuit protection provides supplementary protection against fires that may arise as a result of arcing faults in PV system components or wiring.

What causes an electric arc in a PV system?

om a current passing through a normally non-conductive material such as air.When connecters or cables in a PV system are improperly connected or are dam ged, the electric current may pass through the air, causing an electric arc. Arcs generate heat which can cau

How does an inverter detect an arc fault?

The inverter displays an error message indicating that an arc-fault has been detected, and also transmits an error message through its remote monitoring communications interfaces. A manual restart process is required to resume system operations.
