¶ Advanced Diagnostics (P-Codes)
Access the Diagnostic Page via Settings > Advanced > Integrel Diagnostics. The Diagnostic Page is divided into columns. Each column displays information (parameters) related to individual Integrel system components such as the Integrel Controller, Bank Sensor, or Smart Switch. Parameters are numbered sequentially and provide varying information depending on the component. The following tables provide a decoder for each parameter.

¶ Troubleshooting Table
The following table lists potential issues that may occur during installation, testing, and commissioning.
| Issue | Possible Cause | Solution |
|---|---|---|
| Battery page: No battery data | No CAN bus connection to Bank Sensor | Check RJ45 cable connection between battery bank sensor(s) and Integrel Argo CAN bus network |
| Smart Switch not connecting | No CAN bus connection to Smart Switch | Check RJ45 cable connection between Smart Switch and Integrel Argo CAN network |
| Battery page: Battery showing 0V | Battery voltage tap on backwards | Check voltage taps are wired correctly. If backwards, voltages may be incorrect or zeroed out |
| Battery page: kW reading is backwards (negative when charging, positive when discharging) | Bank Sensor is installed backwards | Contact Integrel Support; this is corrected in settings without rewiring |
| PWM at 100% but no power generation | Blown fuse or generator failure | Contact Integrel Support |
| PWM at 99% but low power generation | 12V supply to controller may be low | Check 12V supply voltage of house bank. If monitoring with 12V Bank Sensor, verify it shows >12.0V |
| PWM at 99% but low power generation | OEG phase cable(s) damaged | Check OEG phase cables are connected and not damaged |
| Engine RPM is incorrect | System configuration needs adjustment | Contact Integrel Support |
| RPM not showing on touchscreen | Phase connections | Check phase connections |
| RPM not showing on touchscreen | Loom fault | Check loom is not damaged. Check noise is not coupling into the loom from nearby cables |
| RPM not showing on touchscreen | System in diagnostic mode | Disconnect USB or Bluetooth, cycle system power |
| RPM not showing on touchscreen | Controller board failure | Check J1939 connection (if enabled). Contact Integrel Support otherwise |
| Touchscreen shows "Max voltage exceeded" | Li-ion setting wrong | Check Li-ion settings |
| Battery voltage dropping below cut out voltage | Load device connected between Smart Switch and battery bank | Check switch settings are correct and check wiring configuration. A single 24V nominal Lithium battery should never drop below 20V |
| Engine seems to be overloaded | System configuration needs adjustment | Contact Integrel Support; several settings interact here and we will review them with you |
| Engine seems to be overloaded | In-gear detection failing | For engines <50hp, check in-gear cable/switch is connected and working. Check J1939 in-gear configuration (Yanmar only) |
| Integrel Panel Switch keeps tripping | Faulty switch | Try a higher current rated switch, no more than 10 amps |
| Integrel Panel Switch keeps tripping | Controller fault | Check voltage to Controller and that PWM is wired correctly |
| Message: Battery missing (Smart Switch) | 48V V tap missing | The 48V V tap for the switch is missing |
| Message: Battery missing (Smart Switch) | Internal fault | Contact Integrel Support |
| Controller has 12V but not powering | Internal fault | Contact Integrel Support |
| Generator temperature reads -77°C | Connection is open circuit or temperature sensor is damaged | Check connection between controller and OEG temperature pins. This may also mean a failed sensor |
| Audible noise in the stereo or audio system, or interference with sensitive DC equipment such as watermaker pumps, while the system is generating | Electrical noise from the E-Power system during generation | Fit the E-Power Noise Suppression Kit, one per Controller. Compatible with all controller versions (Legacy, v4 Molex, and v5 M12). See the installation guide on the Manuals page. The noise is present only while the system is generating |
¶ System Resets
Occasionally a system reset is required to clear errors or restore normal operation.
| Symptom | Reset Type | Check After Reset |
|---|---|---|
| Error on screen that will not clear | Soft Reset | — |
| Start-up self-check warning | Soft Reset | Check 12V supply can deliver 15 amps per controller |
| Error on screen reading ID 0001 or FFFF | Full System Reset | Check network termination and that network uses shielded cables |
| Controller has frozen, fans running continuously | Hard Reset | Check 12V supply can deliver 15 amps per controller. A power drop may cause this issue (may happen during software update if power drops) |
Note: Report any of the above issues to support@integrelsolutions.com
¶ Soft Reset
Power off both controllers, leave for 10 seconds, then repower.
¶ Full System Reset
- Power off the Controllers.
- Disconnect the Integrel Smart Switch (both network and data cables).
- Wait 10 seconds.
- Reconnect the Smart Switch.
- Power on both controllers.
¶ Hard Reset
Warning: A hard reset is rare but may be required if the controller has frozen. Contact Integrel Support before performing a hard reset.
