Inverter Unit: Fail-safe

WARNING: This page is about a different car, the 2018 Nissan Titan XD and 2018 Nissan Titan. However, it is still accessible from the selected car via links, so may be relevant.

When a malfunction listed below occurs, the inverter unit turns OFF the AC 120V outlet main switch indicator and stops the output.

Malfunction item	Fail-safe condition	Fail-safe cancellation condition
Inverter unit power supply voltage is greater than 15V	When inverter unit input voltage rises above 15V, the output will be suspended to protect the inverter unit.	After the inverter unit power supply voltage drops below 15V, the AC 120V outlet main switch ON → OFF → ON operation allows normal return.
Inverter unit power supply voltage is less than 11.5V for 2 seconds or more	When inverter unit input voltage is lowered, the output will be suspended to protect the battery from running out.	After the inverter unit power supply voltage rises above 11.5V, the AC 120V outlet main switch ON → OFF → ON operation allows normal return.
Inverter unit power supply voltage is less than 9V
Inverter unit AC 120V output voltage is greater than 170V	When inverter unit AC 120V output voltage is greater than 170V, the output will be suspended.	After the inverter unit AC 120V output voltage drops below 170V, the AC 120V outlet main switch ON → OFF → ON operation allows normal return.
Inverter unit output current is greater than 3.7A (400W mode)	When inverter unit output current rises above 3.7A, the output will be suspended to prevent over current (e.g., connecting an electric appliance exceeding rated output).	After the inverter unit output current drops below 3.7A, the AC 120V outlet main switch ON → OFF → ON operation allows normal return.
Inverter unit input current is greater than 13.3A (150W mode)	When inverter unit input current rises above 13.3A, the output will be suspended to prevent over current (e.g., connecting an electric appliance exceeding rated output).	After the inverter unit input current drops below 13.3A, the AC 120V outlet main switch ON → OFF → ON operation allows normal return.
Inverter unit is overheated	When the inverter unit is overheated [thermistor temperature above 100°C (212°F)], the output will be suspended to protect the inverter unit.	After the inverter unit temperature is lowered, the AC 120V outlet main switch ON → OFF → ON operation allows normal return.
Inverter unit output signal (AC 120V output signal) is shorted	When inverter unit output signal is shorted, the output will be suspended.	After recovering from inverter unit output signal short, the AC 120V outlet main switch ON → OFF → ON operation allows normal return.
