6 FAQs about [Arc fault solar inverter]

Can a microinverter cause a DC arc fault?

DC arc faults do not occur on solar systems that use microinverters and some systems that use DC optimisers that reduce the DC voltage to safe levels in the event of a fault. Microinverters and DC optimised systems were developed more than 10 years ago to prevent solar fires caused by DC arc faults.

Can a DC arc fault damage a solar inverter?

DC arc faults also cause significant damage to solar equipment. The highest quality DC cabling components can be selected and installed with the greatest care. However, cable insulation and conductor degradation will occur over time, which can cause a DC arc fault. If you see or hear a DC arc fault, can switching off your inverter stop the arc? NO

What causes a DC arc fault in a solar system?

The likelihood of a DC arc fault increases as solar systems age. This is because joints in the DC wiring corrode over time increasing the impedance, causing heat and the breakdown of the continuity of the joint resulting in a DC arc fault.

Can arc detection be integrated in PV inverter equipment and installations?

This article describes what has created the need for arc detection, an analysis of detection methods, and a possible solution to integrate arc detection in PV inverter equipment and installations. There are two types of inverters used in solar PV installations today—microinverters and string inverters.

What causes arcs on PV inverters?

Arcs can occur on both dc and ac side of PV inverters. A disconnection of a cable, for example, may cause a dc arc when high current is flowing. Compounding this problem is the fact that the PV array will supply current continuously while irradiance is occurring on the solar cell. This can lead to continuous arcing and lead to fires.

What is a DC arc fault?

DC arc faults only occur on string inverter systems that have unprotected DC voltage circuits above approximately 80 volts DC. DC arc faults do not occur on solar systems that use microinverters and some systems that use DC optimisers that reduce the DC voltage to safe levels in the event of a fault.
