Alarms & troubleshooting

BATT_DISCHARGE_OVERCURRENT (Battery High-Rate Discharge Overload)
Main DC bus red alarm lit, fuse holder temperature rises rapidly, acoustic alarm active
Mains outage coincident with RF PA peak traffic, discharge draw exceeds 3-hour rating limit (>150A) risking terminal melt
1. Audit DC shunt current telemetry, shed non-essential edge computing and secondary telecom loads; 2. Inspect front terminal cable gauge, ensuring minimum 50mm² high-temperature flame-retardant copper cable; 3. Parallel-connect a second 6-FMX-150B string to share discharge amperage and reduce C-rate stress.
BATT_SHORT_CIRCUIT_RISK (Battery External Circuit Short/Ground Fault Hazard)
Insulation monitor alerts DC bus to earth resistance degraded below 100 Ohms/V; ground fault alarm tripped
Damaged insulating pad on rack cutting cable sheath, missing terminal safety cover, or condensation leakage path
1. Inspect enclosure, verifying flame-retardant terminal insulating protective covers are locked over all terminals; 2. Measure insulation resistance of positive and negative poles to chassis ground with 500V megohmmeter; 3. Eliminate condensation and install rubber grommets/bushings around all cabinet cable pass-through knockouts.
BATT_UNDERCHARGE_SULFATION (Chronic Undercharge & Plate Sulfation Warning)
Controller warns cumulative float undercharge exceeds 30 days; total string internal resistance drifting upward
Cable voltage drop lowers terminal voltage below -53.0V, or prolonged cloudy weather in hybrid solar sites
1. Measure voltage drop between rectifier bus and battery terminals (must not exceed 0.5V); 2. Compensate by raising rectifier float setpoint so voltage directly across terminals reaches nominal -53.5V (2.23V/cell); 3. Execute periodic boost equalizing cycle to dissolve hardened lead sulfate crystals back into active material.
