IVGM5-8K LP2G1 hybrid inverters (fault code list, solid fault LED); warning list uses 92 for remote shutdown alarm
Felicity 92 error code
Parallel version inconsistent (solid LED): inverters in the parallel group run different software versions; in the warning list the same number is the remote shutdown alarm (flashing LED).
Likely causes
- Mixed firmware versions in the parallel group
- A remote shutdown command was received (warning variant)
- Monitoring or remote-control input wired incorrectly
- An interrupted firmware update
Checks to run, in order
- 1Note whether the fault LED is solid (fault) or flashing (warning)
- 2Record the firmware version on every inverter in the group
- 3If flashing, check the remote shutdown input and monitoring platform
- 4Check for an interrupted update
Fixes
- For the solid fault, update every unit to the same firmware with distributor guidance
- For the warning, clear the remote shutdown command
- Restart the group and confirm the versions match
When to escalate
Code 92 needs all parallel units on matching firmware - escalate to the distributor before updating.
Fix it with the right tools
Check the system around the fault before replacing parts: load, battery bank, PV string and commissioning settings. If you need a second opinion, send the code and your inverter model to our team.
Before you open the inverter
- Isolate both the AC and DC sides, then confirm the display is dead before touching terminals.
- Use insulated tools and one hand where possible. DC arcs do not self-extinguish like AC.
- If you see burnt terminals, swollen cells, leaking electrolyte or a burning smell, stop and escalate instead of resetting the fault.
Questions installers ask
What does Felicity 92 mean?
Parallel version inconsistent (solid LED): inverters in the parallel group run different software versions; in the warning list the same number is the remote shutdown alarm (flashing LED).
How do I fix Felicity 92?
For the solid fault, update every unit to the same firmware with distributor guidance For the warning, clear the remote shutdown command Restart the group and confirm the versions match
When should I escalate Felicity 92?
Code 92 needs all parallel units on matching firmware - escalate to the distributor before updating.
Can I reset Felicity 92 myself?
Only after isolating the AC and DC sides and running the checks above. If Felicity 92 returns immediately, stop resetting it and escalate; a repeating fault usually points to a real circuit, battery or hardware problem.
Which models show Felicity 92?
Felicity 92 is documented for IVGM5-8K LP2G1 hybrid inverters (fault code list, solid fault LED); warning list uses 92 for remote shutdown alarm. Confirm the code on your own unit's display or manual before ordering parts.
More Felicity error codes
- Felicity 04Low cell voltage / over-discharge protection.
- Felicity 05PV over-current fault: the PV input current exceeded the inverter's PV input limit.
- Felicity 18PV short-circuit fault on the PV input; in the warning list the same number means battery under-voltage alarm.
- Felicity 19Battery open-circuit alarm: the inverter no longer detects a battery on its terminals.
- Felicity 20Battery SOC low alarm: the battery's state of charge has fallen to the low-SOC warning threshold.
- Felicity 21BMS communication alarm: abnormal communication between battery and inverter in non-SOC mode.
