Vehicle inverter has low voltage alarm and low voltage protection, the car in the engine start when the current requirements are particularly large, at this time the car battery in the rapid discharge, the voltage will drop rapidly. The low voltage alarm of the inverter is generally around 10-11V (12V vehicle inverter), and when the battery voltage is lower than this voltage, the inverter will enter the low voltage alarm, so the traffic light will flash together.

The low-voltage protection of the vehicle inverter is generally about 10.5V, below this voltage, the inverter automatically shuts down. Different manufacturers of inverter low voltage alarm mode is different, some sound, some indicator.
