IVGM5-8K LP2G1 hybrid inverters (fault code list, solid fault LED); warning list uses 93 for flash-not-burned alarm
Felicity 93 error code
Parallel setting inconsistent (solid LED): the parallel configuration differs between units; in the warning list the same number means the flash is not burned (flashing LED).
Likely causes
- Different parallel mode or phase setting between units
- A unit's firmware was never programmed at the factory
- Configuration changed on only one inverter
- Interrupted commissioning
Checks to run, in order
- 1Note whether the fault LED is solid (fault) or flashing (warning)
- 2Compare the parallel mode and phase settings on every unit
- 3Check whether the unit with the warning has valid firmware
- 4Review the commissioning record
Fixes
- Match the parallel settings across the group
- For the flashing warning, arrange firmware programming with the distributor
- Restart the group after the settings match
When to escalate
A flashing code 93 means the flash is not programmed - escalate to the distributor; do not attempt a field flash.
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 93 mean?
Parallel setting inconsistent (solid LED): the parallel configuration differs between units; in the warning list the same number means the flash is not burned (flashing LED).
How do I fix Felicity 93?
Match the parallel settings across the group For the flashing warning, arrange firmware programming with the distributor Restart the group after the settings match
When should I escalate Felicity 93?
A flashing code 93 means the flash is not programmed - escalate to the distributor; do not attempt a field flash.
Can I reset Felicity 93 myself?
Only after isolating the AC and DC sides and running the checks above. If Felicity 93 returns immediately, stop resetting it and escalate; a repeating fault usually points to a real circuit, battery or hardware problem.
Which models show Felicity 93?
Felicity 93 is documented for IVGM5-8K LP2G1 hybrid inverters (fault code list, solid fault LED); warning list uses 93 for flash-not-burned 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.
