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.

 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
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.
