Why is the EXICOM POWER SOLUTIONS Battery Charger showing 'All Rectifier Fail'?
- C
  Christine SosaAug 18, 2025
  The 'All Rectifier Fail' error on your EXICOM POWER SOLUTIONS Battery Charger can occur due to several reasons: * The SMR (Switch Mode Rectifier) might not be communicating, so check the SMR CAN wiring. * An SMR may have been removed; ensure all SMRs are properly inserted. * The SMR might not be ON; verify that the input MCCB is ON and the input voltage is healthy. * There could be a fault in all SMRs; in this case, open the cover and check the SMR red LED. If the red LED is ON, remove each SMR and check them individually.
