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.
