IPV series (IPV-4K24U, IPV-6K48U, IPV-4K24U Pro, IPV-6K48U Pro, IPV-12K48U) — inverter fault code
Itel Energy 14 error code
The inverter's output voltage rose above the permitted level, so the output was switched off.
Likely causes
- Internal output-voltage regulation fault
- Large load switching off and causing an output voltage overshoot
- Surge on the output circuit
Checks to run, in order
- 1Measure the output voltage at the terminals with a true-RMS meter
- 2Compare the meter reading with the LCD, with and without load
- 3Ask whether a large load switched off when the fault appeared
Fixes
- Restart and check the output voltage with a small load
- If the output stays high with no load, return the unit for service
When to escalate
If output voltage measures high with no load connected, escalate for output-stage service before reconnecting loads.
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 14 mean?
The inverter's output voltage rose above the permitted level, so the output was switched off.
How do I fix Itel Energy 14?
Restart and check the output voltage with a small load If the output stays high with no load, return the unit for service
When should I escalate Itel Energy 14?
If output voltage measures high with no load connected, escalate for output-stage service before reconnecting loads.
Can I reset Itel Energy 14 myself?
Only after isolating the AC and DC sides and running the checks above. If Itel Energy 14 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 14?
Itel Energy 14 is documented for IPV series (IPV-4K24U, IPV-6K48U, 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.
