What to do if the 'GRID' LED is blinking on my CPS Inverter?
If the 'GRID' LED on your CPS Inverter is blinking, take the following steps: 1. Turn off the external AC breaker. 2. Switch the DC switch to the 'OFF' position. 3. Verify that the grid voltage is within the normal range and that the AC side cable connection is correct and securely fastened.
How to troubleshoot when the 'Power' LED and LCD screen don't light up on a CPS SCA60KTL-DO/US-480?
If neither the 'Power' LED nor the LCD screen on your CPS Inverter is lighting up, please do the following: 1. Turn off the external AC breaker. 2. Switch the DC switch to the 'OFF' position. 3. Check the PV input voltage and polarity.
What to do if my CPS Inverter shows TempOver (Over-temperature protection) error?
To address the over-temperature protection issue (TempOver) on your CPS Inverter: 1. Make sure the surrounding temperature is within the inverter's operating range. 2. Check for any blockages at the air inlet. 3. Ensure the fan isn't obstructed. 4. Verify the installation location is suitable. 5. Wait for 30 minutes to see if the alarm clears. 6. If the issue persists, further assistance may be needed.
What to do if my CPS Inverter displays Warn0040 (DC SPD) error?
To resolve a Warn0040 (DC SPD) error on your CPS Inverter: 1. Visually inspect the DC Surge Protection Device (SPD). 2. If the indicator is red, replace the SPD module. 3. If the indicator is green, remove and reinstall the SPD module in its socket. If the problem continues, further assistance may be needed.
What to do if my CPS Inverter displays GFCIErr (leakage current high)?
If your CPS Inverter displays a GFCIErr (leakage current high) message, check the PV and ground wires: 1. Turn OFF the AC switch to disconnect from the grid. 2. Open the fuse holders to isolate the PV strings and test them with a string test set. 3. Add one PV string at a time and start up the inverter to see if the alarm occurs. 4. If no alarm, turn OFF AC switches to disconnect from the grid and add the next string, then start the inverter again. 5. Continue until you identify the string that triggers the alarm, then trace back the faulted string to find any leakage to Earth Ground.
What to do if my CPS Inverter displays Protect0020 (Grid relay error)?
To address a Protect0020 (Grid relay error) on your CPS Inverter: 1. Restart the inverter by turning both the AC and DC switches off, wait one minute, and then turn them back on. 2. If the fault persists, the inverter may need to be replaced.
What to do if my CPS Inverter displays Protect0030 (Inverter Over Current)?
To resolve a Protect0030 (Inverter Over Current) error on your CPS Inverter: 1. Restart the inverter by turning both AC and DC switches off, waiting one minute, and then turning them back on. 2. If the fault persists, the inverter may need replacement.
What to do if my CPS Inverter displays Protect0150 (Mini MCU Fault)?
To address a Protect0150 (Mini MCU Fault) on your CPS Inverter: 1. Restart the inverter by turning both the AC and DC switches OFF, wait for 1 minute to allow all energy to discharge, and then turn both switches ON. 2. If the inverter cannot clear the fault, it may need to be replaced.
What to do if my CPS Inverter displays Protect0090 (Bus over voltage)?
To address a Protect0090 (Bus over voltage) error on your CPS Inverter: 1. Restart the inverter by turning both the AC and DC switches off. Wait for one minute to allow all energy to discharge, then turn both switches on. 2. If the inverter cannot clear the fault, it may need to be replaced.
What to do if my CPS Inverter displays Protect0110 (BUS over voltage (firmware))?
To address a Protect0110 (BUS over voltage (firmware)) error on your CPS Inverter: 1. Restart the inverter by turning both the AC and DC switches OFF. Wait for 1 minute for all energy to discharge, then turn both switches ON. 2. If the inverter cannot clear the fault, it may require replacement.
