Troubleshooting
NOTE: If a battery has three of the same error in a span of five minutes, the battery will lockout on the third error detection. The
solution is to fully power cycle the battery to clear the lockout error.
Event / Error Description Solution
Excess charge current Reduce the charging current to the battery from all charging sources.
Excess battery load(s) Reduce discharging current from the battery by reducing load consumption.
System Short Circuit Disable all battery connected systems and check for a system wide short circuit.
Internal battery error Power cycle the battery by turning it OFF and then ON.
If the error persists, contact technical support.
Internal temperature sensor
error
Power cycle the battery by turning it OFF and then ON.
If the error persists, contact technical support.
Cell voltage too high An internal battery cell has been overcharged in the battery. Remove by disconnecting all charging
sources and wait for the error to resolve by itself.
If the error persists, contact technical support.
Cell voltage too low An internal battery cell is over discharged. Disconnect all loads connected to the power system. Check
your charging source and be sure to use an approved charging source such as a Xantrex charger or
inverter/charger.
Battery voltage too high The battery has been overcharged. Remove by disconnecting all charging sources and check the
charger settings to ensure that a compatible battery type has been configured such as LFP.
If the error persists, contact technical support.
Battery voltage too low The battery has been over discharged. Charge the battery and check the Low Voltage Disconnect setting
on the Xantrex charger or inverter/charger or the SoC meter, if available.
If the error persists, contact technical support.
Battery is too hot to charge The battery is too hot to operate correctly during its charge cycle. Decrease the ambient heat in the
immediate battery environment, if possible or check for other environmental causes and safely remove
the cause.
Battery is too hot to
discharge
The battery is too hot to operate correctly during its discharge cycle. Decrease the ambient heat in the
immediate battery environment, if possible or check for other environmental causes and safely remove
the cause.
Battery is too cold to charge The battery is too cold to operate correctly during its charge cycle. Increase the heat in the immediate
battery environment by safely introducing a heat source.
Battery is too cold to
discharge
The battery is too cold to operate correctly during its discharge cycle. Increase the heat in the immediate
battery environment by safely introducing a heat source.
Battery temperature
differential is too high during
charging
Leave the battery at room temperature for several hours.
If the error persists, contact technical support.
Battery temperature
differential is too high during
discharging
Leave the battery at room temperature for several hours.
If the error persists, contact technical support.
BMS temperature is too high
during charge or discharge
The battery is too hot to operate correctly during its cycle.
Decrease the ambient heat in the immediate battery environment, if possible. Or check for other
environmental causes and safely remove the cause.
