Connecting the Remote Controller to your Power Inverter

  1. Using the RJ-45 Remote Control Cable, connect the Remote On/Off Controller to the RJ-45 cable jack (Labeled REMOTE) on the front of your power inverter
  2. Press the POWER button on the Remote On/Off Controller to turn on your inverter
  3. When the inverter is powered on the Input Voltage LED is green

Once the remote is connected, you can turn the power ON or OFF from both the inverter and the remote controller. On smaller models having a push-button ON/OFF switch, it does not matter whether the power button is in the ON or OFF position when using the remote. The remote will function as your ON or OFF switch when the power button is in either position.


Your Cobra Remote On/Off Controller with Fast Charge USB is compatible with all Cobra PRO, PURE SINE, and POWER Series power inverters. These inverters, when used with the Remote On/Off Controller, will support the Remote’s Fast Charge and audible alarm features as well as turn the inverter ON when in OFF mode. Additionally, if you purchased a PRO Series Inverter, the LCD will display INPUT and OUTPUT as well as fault messaging as shown below.If you purchased a PURE SINE 400W or POWER 500W Inverter, see the COBRA PURE SINE OR POWER SERIES REMOTE DISPLAY MESSAGING section on page 9 for details.


Standby ModeWhen you plug in the Remote On/Off Controller with Fast Charge USB and press the power button to ON, the display will show AC Output (Watts being used) and the DC Input (Battery Volts). The images below show the messaging on the LCD display when the remote is turned ON or OFF.

NOTE: Backlight automatically turns off 5 seconds after pressing the POWER button.

Fault MessagingYour inverter and remote are equipped to sound an alarm to alert you when power requirements or battery voltage is not in range. This is considered a “fault”. When this happens, both the inverter and remote alarms will sound, and if the fault is not addressed, the inverter will shut down and the remote will display a fault message. Below is a list of “faults” and the messaging that will appear on the LCD display when these faults occur.

DC Input Low Voltage Alarm (Default Setting)The alarm will sound when the battery is at 11.5V.
DC Input Low Voltage Cutoff (Default Setting)The alarm will sound and the inverter will shut down when the battery is at 10.5V.
DC Input Low Voltage Alarm (Alternate Setting)The alarm will sound when the battery is at 10.5V.
DC Input Low Voltage Cutoff (Alternate Setting)The alarm will sound and the inverter will shut down when the battery is at 9.5V.
DC Input HighVoltage Alarm The alarm will sound when the battery is at 15.0V
AC Output ShortThe alarm will sound and the inverter will shut down when the AC output is shorted.
AC Output OverloadThe alarm will sound and the inverter will shut down when the AC output exceeds the inverter limits.
Inverter Over TemperatureThe alarm will sound and the inverter will shut down when the inverter overheats.
GFCI TripThe alarm will sound and the inverter will shut down when a Ground Fault is detected.


If you purchased a Cobra POWER 500W or PURE SINE 400W inverter, the remote display will display the operating status of your inverter when plugged in.

NOTE: Backlight turns off after 5 seconds from pressing the POWER

Fault DefinitionsWhen the Remote On/Off Controller is plugged into a PURE SINE 400W or POWER 500W inverter and a fault occurs due to Low Voltage, Over Voltage, Over Temperature or Battery Over Voltage, the remote and the inverter will sound an alarm, and the remote will show “ERROR CHECK INVERTER” on the display (as shown above). The alarm and “ERROR” message indicating an issue and the fault will need to be addressed in order to use and operate your inverter properly. Below is a list of faults that will trigger the alarm and “ERROR” message on the remote display.

  • An alarm will sound on the remote and inverter when the following occurs:– DC Input Low Voltage – battery reaches 10.5V signaling you to charge the vehicle battery (this can be done by turning on the vehicle)If an alarm occurs and your inverter continues to work with the above, this means the fault is occurring at the battery and needs to be immediately addressed. If the alarm is ignored, the remote will continue to display the ERROR message and the inverter will work until reaches its cutoff limit and shut down.
  • An alarm will sound and the inverter will shut down when the following faults occur:– DC Input Low Voltage Cutoff – battery has reached 9.5V and needs to be recharged immediately– DC Input High Voltage Cutoff – when the battery reaches 15.5V (can occur when a momentary surge spikes the battery Voltage)– AC Output Short – AC output is shorted (short circuit)– AC Output Overload – AC output load exceeds inverter AC output load limits (try unplugging some of your devices)– Inverter Over Temperature – the inverter is overheating (check for proper ventilation)– GFCI Trip – a Ground Fault is detected

If the inverter shuts down, the “ERROR CHECK INVERTER” message will display on the remote.


Problem/Symptom  Possible Cause  Troubleshoot 
Remote will not turn ON Remote cable connection,battery connection, or carbattery needs recharging 1. Check cable connection at remote and inverter2. If these are secure and the remote will still notturn on, check cable connection from the inverter to the battery or the CLA
