F47

DC Under Voltage

Schneider Electric · XW Pro NA Operation Guide

What does F47 mean?

This Automatic Fault occurs as an immediate DC under-voltage shutdown if the DC voltage drops below 32 V. The fault automatically clears, and the inverter restarts when the DC voltage reaches V+4 V (36V), pointing to potential battery or load issues.

Complete Troubleshooting Guide

  1. 1

    Check for the correct battery voltage at the inverter’s DC input terminals.

  2. 2

    Check for an external DC load on the batteries.

  3. 3

    Check condition of batteries and recharge if possible.
