How to fix CommErr on my CPS SCA Inverter?
To address a CommErr on your CPS Inverter: - Observe for 5 minutes to see if the alarm clears automatically, as the terminal block connectors of internal communication wires might have poor contact. - If the problem persists, switch off the 3-phase working power supply and then reboot the system.
Why is the GRID LED blinking on my CPS Inverter?
If the GRID LED is blinking on your CPS Inverter, try the following: - Turn off the external AC breaker. - Switch the DC switch to the “OFF” position. - Check that the grid voltage is normal and the AC side cable connection is correct and secure.
What does it mean if my CPS Inverter displays TempOver (Over-temperature protection)?
If your CPS Inverter displays TempOver (Over-temperature protection), take the following steps: - Confirm that the external ambient temperature is within the specified operating range. - Check if the air inlet or fan is blocked. - Verify that the installation location is appropriate. - Observe for 30 minutes to see if the alarm clears automatically.
What to do if my CPS SCA displays Protect0020 (Grid relay error)?
If your CPS Inverter displays a Protect0020 (Grid relay error), try restarting the inverter by turning both the AC and DC switches off, waiting one minute, and then turning them back on to allow all energy to discharge. If the fault continues, the inverter may need to be replaced.
What to do if my CPS SCA displays Fault0100 (Grid relay fault)?
If your CPS Inverter displays a Fault0100 (Grid relay fault), try restarting the inverter by turning both the AC and DC switches off, waiting one minute, and then turning them back on to allow all energy to discharge. If the fault persists, consider replacing the inverter.
What to do if my CPS SCA shows GridV.OutLim error?
If your CPS Inverter displays a GridV.OutLim error, first ensure that the grid connection is properly established. If the problem persists, try restarting the inverter.
What to do if my CPS Inverter displays Fault0080 (Bus Hardware over current fault)?
If your CPS Inverter displays a Fault0080 (Bus Hardware over current fault), try restarting the inverter by turning both the AC and DC switches off, waiting one minute, and then turning them back on to allow all energy to discharge. If the fault continues, the inverter may need to be replaced.
What to do if my CPS SCA Inverter displays Protect0150 (Mini MCU Fault)?
If your CPS Inverter displays a Protect0150 (Mini MCU Fault), try restarting the inverter by turning both the AC and DC switches off, waiting one minute, and then turning them back on to allow all energy to discharge. If the fault persists, consider replacing the inverter.
What to do if my CPS SCA displays Fault0130 (Bus over total voltage)?
If your CPS Inverter shows a Fault0130 (Bus over total voltage) error, try restarting the inverter by turning both the AC and DC switches off, waiting one minute, and then turning them back on to allow all energy to discharge. If the fault continues, the inverter may need to be replaced.
What to do if my CPS SCA Inverter displays Protect0030 (Inverter Over Current)?
If your CPS Inverter displays a Protect0030 (Inverter Over Current) error, try restarting the inverter by turning both the AC and DC switches off, waiting one minute, and then turning them back on to allow all energy to discharge. If the fault persists, consider replacing the inverter.
