HE-GF-FLA-48500 Manual_20250327_EN.pdfC02Battery undervoltage.Fault
Pack-level under-voltage fault displayed on the LCD BMS fault code / flag screen (section 4.4).
Pack voltage fell below the BMS under-voltage threshold during discharge, typically near the 48 V cut-off voltage (section 2.4). The Special Attention note on page 1 warns that an over-discharged pack cannot be repeatedly activated and may fail to be activated by the AC or PV activation cable.
Restart the unit, if the error persists, contact the repair center. Stop the load and recharge from mains or PV as soon as possible (page 1 Special Attention).
