Removing C9 Capacitor from a faulty Wi-Fi board

Removing C9 (short circuit component) from a Faulty Wi-Fi Card 

Kindly note that prior to executing the procedure, the installer must first obtain 3rd Party Repair authorisation from Sunsynk Support on a case-by-case basis. 

Furthermore, the installer acknowledges that in the improbable event of any damage occurring to the inverter during this 3rd Party Repair process, responsibility for such damage falls upon the installer. Consequently, any subsequent repairs necessitated by said damage will be subject to applicable charges.

Please refer to the attached instruction document:

Removing C9 (short circuit component) from a Faulty Wi-Fi Card

Kindly note that prior to executing the procedure, the installer must obtain authorisation from Sunsynk Support on a case-by-case basis. Furthermore, the installer acknowledges that in the improbable event of any damage occurring to the inverter during the process, responsibility for such damage falls upon the installer. Consequently, any subsequent repairs necessitated by said damage will be subject to applicable charges.
Before beginning any work, please ensure the AC and DC supplies powering the inverter have been isolated.

1. Remove the front cover from the inverter. (Optionally remove the plastic cover if required for more access).
   

2. Unscrew the 2 screws on the Wi-Fi board that is to be replaced.
   

3. Lift the Wi-Fi card away from the inverter.
   

4. Identify the C9 Capacitor immediately adjacent to the P2 connector. Using a multimeter, test across C9 for 12V DC. If 12V DC is not present, C9 has become short circuit. Using fine electronic cutters or snips, very carefully remove C9 from the PCB board.
   

5. Reattach the Wi-Fi board to the inverter casing with the two screws. Also reattach the plastic cover if removed.

To check if the repair was successful, when the inverter is powered back on and a datalogger is plugged in, the datalogger should now light up.
