  To resolve a Protect0100 (The sensor fault of leakage current) error 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, further assistance may be needed to replace the Filt board or inverter.

What to do if my CPS Inverter displays GFCIErr (leakage current high)?
- A
  Angel ChapmanAug 27, 2025
  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 does ExtFanErr mean on my CPS Inverter and how to fix it?
- W
  Walter ButlerSep 6, 2025
  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.
