IPV Pro series (IPV-4K24U Pro, IPV-6K48U Pro, IPV-12K48U) — inverter fault code
Itel Energy 44 error code
The PV current sensor has failed.
Likely causes
- PV current-sensor circuit failed
- Sensor damaged by a PV-side short or surge
- Internal sensor connector or wiring fault
Checks to run, in order
- 1Compare the LCD PV current with a clamp meter
- 2Check for a recent PV short or reverse polarity
- 3Restart and see whether the code clears
Fixes
- Restart the unit once
- If the code returns, return the unit to the repair centre
When to escalate
Code 44 is an internal sensor failure; escalate to the distributor for PV input board service.
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 Itel Energy 44 mean?
The PV current sensor has failed.
How do I fix Itel Energy 44?
Restart the unit once If the code returns, return the unit to the repair centre
When should I escalate Itel Energy 44?
Code 44 is an internal sensor failure; escalate to the distributor for PV input board service.
Can I reset Itel Energy 44 myself?
Only after isolating the AC and DC sides and running the checks above. If Itel Energy 44 returns immediately, stop resetting it and escalate; a repeating fault usually points to a real circuit, battery or hardware problem.
Which models show Itel Energy 44?
Itel Energy 44 is documented for IPV Pro series (IPV-4K24U Pro, IPV-6K48U Pro, IPV-12K48U) — inverter fault code. Confirm the code on your own unit's display or manual before ordering parts.
More Itel Energy error codes
- Itel Energy 01Display code 01 covers two events: as a warning it signals output overload (flashing fault LED, two beeps per second); as a fault it signals DC bus over-voltage (solid fault LED, output switched off).
- Itel Energy 02Display code 02 covers two events: as a warning it signals the upper cooling fan is locked (three beeps); as a fault it signals DC bus under-voltage (solid fault LED, output switched off).
- Itel Energy 03Display code 03 covers two events: as a warning it signals the lower cooling fan is locked (three beeps); as a fault it signals that the DC bus soft-start sequence failed (solid fault LED).
- Itel Energy 04Grid voltage is above the upper limit of the inverter's grid window; warning only, with no buzzer alarm.
- Itel Energy 05In a parallel system the AC outputs of the units are not connected together, or a unit is running on a different phase.
- Itel Energy 06Remote shutdown is enabled, typically from the monitoring app over Wi-Fi, so the inverter is being held off remotely.
