LOAD-01Cross-brand / Protocol · Power cabinet / LMSFree sampleDynamic load management caps to 0 A
Dynamic load management caps to 0 A (LOAD-01) — Load management field fault. Stay OEM-agnostic until the protocol stage pins a hardware path; capture SECC/OCPP/vehicle evidence before opening the cabinet.
CFG-03Cross-brand / Protocol · DC Fast ChargersFree samplePower module map incorrect after expansion
Power module map incorrect after expansion (CFG-03) — Configuration field fault. Stay OEM-agnostic until the protocol stage pins a hardware path; capture SECC/OCPP/vehicle evidence before opening the cabinet.

BESS-UVFluence / BESS · BESSFree sampleBESS undervoltage at cabinet
Fluence BESS reports an undervoltage (UV) inhibit at the EVSE feed — either the PCS AC output or the shared DC bus — so dependent chargers brown out mid-session or latch Faulted while the BESS HMI independently alarms UV. It shows up most on hot afternoons when several dispensers ramp together and SOC is already drawn down from an overnight fleet pull, so the first minutes of triage are about proving whether the EVSE is really broken or the depot just asked for more than the BESS could deliver at that SOC.
BESS-OVFluence / BESS · BESS solo+BESS overvoltage trip
Fluence BESS overvoltage (OV) protection trips and opens the discharge/charge path feeding the EVSE bus, so dependent di…
