What does Warn0030 (EepromErr) mean on my CPS SCA Inverter and how to fix it?
If your CPS Inverter shows Warn0030 (EepromErr), observe for 5 minutes to see whether the alarm will be eliminated automatically.
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 Inverter displays PVVoltOver?
To address a PVVoltOver error on your CPS Inverter: - Measure the voltage at the DC terminals in the wire-box and compare it with the reading in the Measurement menu. Ensure the PV voltage is less than 1500V in open circuit condition. - If the display reading isn't within 2% of the meter reading, consider replacing the inverter. - If the display reading is within 2% of the meter reading, adjust the number of panels in the string.
What does Warn0050 (TempSensorErr) mean on my CPS SCA Inverter and how to fix it?
If your CPS Inverter displays Warn0050 (TempSensorErr), observe the temperature display. If the issue persists, switch off the 3-phase working power supply and then reboot the system.
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.
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 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)?
If your CPS Inverter displays a Protect0090 (Bus over 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.
