Hyundai Santa Fe (TM): AC Inverter System

Hyundai Santa Fe TM 2019-2023 Service Manual / Body Electrical System / AC Inverter System

Description and operation

Description

An inverter is a device that transforms the DC voltage from the battery into an AC voltage (220 V). The inverter can power various electrical devices that consume 200 W or less, including mobile phone or notebook rechargers, audio systems, and TVs.

Inverter System Protection Function

Item	Condition	LED Status
Undervoltage protection	Shuts down for safety at voltages lower than 11.3 V ± 0.3 V.	LED flickering
Undervoltage protection	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
Overvoltage protection	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
Overheat protection	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 its 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.	LED OFF
undervoltage/overvoltage shutdown protection	Shuts down at voltages lower than 10.7 V ± 0.3 V.	LED OFF
undervoltage/overvoltage shutdown protection	Shuts down at voltages lower than 16.5 V ± 0.3 V.	LED OFF

–	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 220 V (200 W) of power.

–	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.
