Kia Niro: AC Inverter System / Description and operation


An inverter is a device that transforms the DC voltage from the battery into an AC voltage (115V). The inverter can power various electrical devices that consume 150W or less, including mobile phone or notebook rechargers, audio systems, and TVs.

Inverter system Protection Function

LED Status
Undervoltage protection
Shuts down for safety at voltages lower than 11.3 V ± 0.3 V.
LED flickering
Resumes operation at 12.2 V ± 0.3 V.
LED lighting
Overvoltage protection
Shuts down for safety at voltages higher than 15.5 V ± 0.3 V.
LED flickering
Resumes operation at 15.5 V ± 0.3 V.
LED lighting
Overheat protection
Shuts down for safety if temperatures exceed 105°C ± 10°C.
LED flickering
Resumes operation at 95°C ± 10°C.
LED lighting
Overcurrent protection
Turns OFF when overcurrent above a set point is detected.
LED lighting
The inverter stops for 20 seconds before it restarts.
LED flickering
(20 seconds)
Turns OFF when overcurrent is detected 3 times. (Turn the AC inverter switch ON again to turn on the inverter.)
short circuit protection
The inverter shuts down for safety if there is a short circuit between the AC1 and AC 2 outputs during operation.
undervoltage/overvoltage shutdown protection
Shuts down at voltages lower than 10.7 V ± 0.3 V.
Shuts down at voltages lower than 16.5 V ± 0.3 V.


DO NOT touch or insert any foreign substance into the AC inverter. Be aware of the potential risk of electric shock or fire.


Only use the AC inverter when the engine is running. Always disconnect the inverter when not in use.

Using the AC inverter when the engine is off or leaving an electric device plugged in for a long time may drain the battery of the vehicle.

DO NOT use any electric devices that consume more than 115V (150W) of power.

Some electric devices may not operate properly even though they consume less power than rated capacity of inverter provided by the vehicle.

Household appliances that require high voltage at initial operation (e.g. compressor operated refrigerator, electrically powered tools, etc.)

Measuring equipment used to process accurate data (e.g. medical equipment, precision measuring equipment, etc.)

Equipment that requires stable power supply (e.g. electric blanket/mattress, touch sensor lighting, etc.)

Connecting an electrical device that generates excessive levels of electromagnetic noise to the AC inverter may cause abnormal sounds in the audio equipment or a malfunction in the vehicle's electronic devices.

Connecting a faulty electronic device to the AC inverter may damage the inverter or the electric system of the vehicle.


The LED indicator blinks if the AC inverter input voltage falls below 11.3 V. The inverter shuts off if the voltage falls below 10.7 V.

Inspect the battery and recharging system.
