What to do if my CPS Inverter displays Protect0170 (DCI high)?
To address a Protect0170 (DCI high) error on your CPS Inverter: 1. Increase the limit of DCImax (for example, to 400mA) to give the inverter more flexibility in handling transient conditions and voltage imbalances between grid phases. 2. If the inverter still shows the error after raising the limit, it may need to be replaced.
What does ExtFanErr mean on my CPS Inverter and how to fix it?
If you see the ExtFanErr message on your CPS Inverter: If the fan is spinning: Replace the inverter, as the sensing circuit may be faulty. If the fan is not spinning: Remove the six bolts holding the two external fans in place. Open the white, snap-on wire connector. Measure the voltage between the pins connected to the RED and BLACK wires. If the voltage is below 6VDC, replace the inverter. If the voltage is higher than 6V, replace the fan.
What to do if my CPS Inverter displays IsolationErr (Insulation resistance low)?
If your CPS Inverter displays the message IsolationErr (Insulation resistance low), 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 the AC switches to disconnect from the grid, add the next string, and start up the inverter again. 5. Continue until you can find the string that triggers the alarm. Trace back the faulted string to find any leakage to Earth Ground. Note: The parameter “ISOResist” in the hidden menu can be adjusted.
How to troubleshoot TempSensorErr on my CPS Inverter?
To troubleshoot a TempSensorErr on your CPS Inverter, follow these steps: 1. Observe the temperature display. 2. Switch off the external AC disconnect and then switch it back on to reboot the system. 3. If the issue is not resolved, further assistance may be needed.
What to do if my CPS Inverter displays Warn0050 (TempSensorErr)?
If your CPS Inverter displays the message Warn0050 (TempSensorErr): 1. Observe the temperature display. 2. Switch off the external AC disconnect, then back on to reboot the system. 3. If the issue persists, further assistance may be needed.
