How to fix a Ground I Fault on a Clenergy SPH15 Inverter?
- R
  Richard SmithSep 9, 2025
  A Ground I Fault on your Clenergy Inverter indicates excessive ground current. To address this: 1. Disconnect the inverter from the grid power. 2. Carefully inspect the AC wiring and connection system. 3. After resolving the cause, reconnect the inverter to the grid power and check its status. If the problem persists, the GFCI circuit may be faulty, and you should contact your inverter service representative.

What should I do if my Clenergy Inverter displays PV Over Voltage?
- S

  If your Clenergy Inverter is showing a PV Over Voltage error, start by checking the PV open-circuit voltage, making sure it is less than 500VDC. If the PV voltage is significantly lower than 500VDC (e.g., less than 430V), measure the DC voltage using a multimeter and compare the readings with the LCD display. If the readings differ by more than 5%, contact your inverter service representative.

How do I troubleshoot an Isolation Fault on my Clenergy SPH15?
- G
  Geoffrey RodgersSep 13, 2025
  To troubleshoot an Isolation Fault on your Clenergy Inverter, check the impedance between PV (+) & PV (-) and earth ground, ensuring it exceeds 8MΩ. A lower impedance may indicate a ground fault in the PV array or wiring, requiring assistance from your PV array service provider or electrician. If these steps do not resolve the issue, the isolation detection circuit might be faulty, and you should contact your inverter service representative.

What to do if Clenergy SPH15 Inverter shows Consistent or Mismatch Fault?
- P
  Paige SimpsonSep 18, 2025
  A Consistent or Mismatch Fault on your Clenergy Inverter suggests inconsistencies between the main (master) and redundant (slave) controllers. To resolve this, disconnect either PV (+) or PV (-) from the input and then restart the unit. If this does not correct the problem, contact your inverter service representative.
