This is the complete fault table for the Felicity LPBF48200-H Battery family — 13 codes shared by 2 model numbers, transcribed from the official manual. On this Felicity device, a fault code means the unit has entered protection and stopped normal operation; a warning leaves it running. The exact indication (LED pattern or display code) is listed per code below.
Last checked against the official manuals on July 10, 2026.
Battery pack overall voltage above protection threshold (BMS protection).
CauseTotal battery voltage has exceeded the BMS upper voltage limit.
Recommended fixRestart the unit; if the error persists, contact the repair center.

Battery pack could not satisfy parallel-operation conditions (e.g. voltage difference between local and other packs >3V, or wiring issue).
CauseSingle unit configured as parallel slave, mis-wired parallel connection, or voltage mismatch (>3V) between paralleled packs.
Recommended fix1. Please check if single unit is installed to parallel system. 2. if this error happens during parallel installation, please check wires connection. if they are connected correctly, please finish parallel installation first, and then restart the unit. 3. if the problem remains, please contact your installer.
