What to do if my EG4 Battery Pack shows different SOC value of batteries in parallel operation?
If your EG4 Battery Pack shows different SOC value of batteries in parallel operation, deep discharge the battery bank (less than 20% SOC), then charge battery bank fully.
Why is my EG4 Battery Pack power supply unstable?
An unstable power supply in your EG4 Battery Pack may occur because the battery capacity is not at full power. Check the battery cable connection to ensure it is properly connected.
What to do if my EG4 LL shows ALM LED always on?
If the ALM LED on your EG4 Battery Pack is always on, it indicates a short circuit. Disconnect the power cable and inspect all cables for damage or improper connections.
What to do if my EG4 Battery Pack has a discharge short-circuit?
If your EG4 Battery Pack experiences a discharge short-circuit, it means the discharge current is too high. Turn the BMS and breaker off and then back on to reset. Also, lower the loads connected to the battery.
How to fix EG4 LL inverter communication failure?
To address an inverter communication failure with your EG4 Battery Pack: * Check the communication port connection. * Verify the battery ID setting. If needed, input the proper “host” battery DIP switch address and power cycle the battery.
What to do if my EG4 LL Battery Pack has a cell over-voltage?
If your EG4 Battery Pack is showing a cell over-voltage, check individual cell voltage in BMS Tools.
What to do if my EG4 Battery Pack has a charge under-temperature?
If your EG4 Battery Pack indicates a charge under-temperature, power off the module and warm up the location.
What to do if my EG4 LL has a discharge under-temperature?
If your EG4 Battery Pack indicates a discharge under-temperature, power off the module and warm up the location.
What to do if my EG4 LL Battery Pack has a pack under-voltage?
If your EG4 Battery Pack shows a pack under-voltage, the module needs to be charged.
What does it mean if ALM LED flashes 20 times with SOC1 LED on in my EG4 LL Battery Pack?
If the ALM LED flashes 20 times with the SOC1 LED on your EG4 Battery Pack, it indicates unbalanced voltage within a cell. To resolve this, deeply discharge the battery bank (less than 20% SOC) and then fully charge it.
