What does IntFanErr mean on my CPS Inverter?
- BBrandon ReynoldsSep 23, 2025
If your CPS Inverter displays IntFanErr, it means the inverter needs to be replaced.
What does IntFanErr mean on my CPS Inverter?
If your CPS Inverter displays IntFanErr, it means the inverter needs to be replaced.
What to do if my CPS Inverter displays Protect0070 (Bus imbalance)?
To address a Protect0070 (Bus imbalance) error on your CPS Inverter: 1. Increase the limit of IDCmax (for example, to 400mA) to allow the inverter more room to adjust in transient conditions to cope with impedance and voltage imbalances between Grid phases. 2. If the alarm still occurs after adjustment, the inverter may need to be replaced.
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 Protect0090 (Bus over voltage) error?
If your CPS Inverter shows a Protect0090 (Bus over voltage) error, try restarting the inverter by turning off both AC and DC switches, waiting one minute to allow all energy to discharge, and then turning them back on. If the fault persists, the inverter may need to be replaced.
What to do if my CPS SCA displays Protect0030 (Inverter Over Current) error?
If your CPS Inverter displays a Protect0030 (Inverter Over Current) error, try restarting the inverter by turning off both AC and DC switches, waiting one minute to allow all energy to discharge, and then turning them back on. If the fault continues, the inverter may require replacement.
What to do if my CPS SCA Inverter displays Protect0070 (Bus imbalance) error?
If your CPS Inverter shows a Protect0070 (Bus imbalance) error, try increasing the limit of IDCmax (for example, to 400mA) to give the inverter more flexibility to adjust during transient conditions, which can help with impedance and voltage imbalances between Grid phases. If the alarm persists after this adjustment, the inverter may need to be replaced.
What to do if my CPS SCA shows ExtFanErr?
If your CPS Inverter is showing an ExtFanErr, observe it for 5 minutes to see if the alarm clears automatically. Check the fan blades for any obstructions. You can also try switching off the 3-phase work power supply and then rebooting the system. The error may be caused by the fan being blocked, the fan's service life expiring, or a poor connection at the fan socket.
What to do if my CPS Inverter displays a CommErr error?
If your CPS Inverter displays a CommErr, first, observe the inverter for 5 minutes to see if the alarm clears automatically. If it doesn't, switch off the 3-phase working power supply and then reboot the system. This error may be due to poor contact in the terminal block connectors of the internal communication wires.
What to do if my CPS SCA Inverter displays Warn0050 (TempSensorErr)?
If your CPS Inverter shows Warn0050 (TempSensorErr), observe the temperature display. You can also try switching off the 3-phase working power supply and then rebooting the system.
What to do if my CPS Inverter displays Warn0030 (EepromErr)?
If your CPS Inverter is showing Warn0030 (EepromErr), observe it for 5 minutes to see if the alarm is eliminated automatically.
