How your PV system detects and prevents fault arcs

Read this blog to find out how your photovoltaic system detects and prevents arc faults.

Arc Fault Detection in SolarEdge Inverters

Enable and test arc fault detectionUsing SetAppTo enable Manual Reconnect or A utomatic Reconnect (Europe and APAC only):To resume system operation, perform a manual restart as follows:To troubleshoot self-test failures:To enable or disable arc detection:To enable Manual Reconnect or Auto Reconnect (Europe and APAC only):To resume system operation, perform a manual restart as follows:To troubleshoot self-test failures:If the self-test fails, an error message displays indicating that the arc detector hardware failed during the wake-up tests. If the inverter is connected to the monitoring platform, the error is displayed there as well. The inverter continuously repeats the arc detection self-test until it is successful. If the problem persists, contact support.See more on knowledge-center.solaredge SMA America
