PV & BESS fault library
Every fault and failure mode NuraVolt detects across solar PV and battery storage — what it looks like in the data, what causes it, what it costs, and how physics-informed ML flags it early.
PV string underperformance
A string delivering less current than its peers under the same irradiance.
Read moreInverter clipping
AC power held flat at the inverter rating while DC is available.
Read moreMPPT imbalance
Unequal power across the MPPT inputs of a single inverter.
Read moreDC insulation resistance degradation
Falling insulation resistance on the DC side — a safety-critical fault.
Read moreInverter IGBT overtemperature
Power-stage overheating from cooling failure or a blocked heat sink.
Read moreSoiling loss
Energy lost to dust, dirt, and deposits on the module glass.
Read moreBESS capacity fade
Loss of usable battery capacity as State of Health declines toward warranty limits.
Read moreBESS cell imbalance
Growing voltage spread between cells in a battery string.
Read moreBESS thermal stress
Cumulative high-temperature exposure that accelerates battery degradation.
Read moreBESS round-trip efficiency decay
Falling round-trip efficiency as internal resistance rises.
