What does the code AC 3 mean when appearing on the digital display of my Predator 3500 Inverter?

He is asking about DC inverter AC and you all idiots giving solution of washing machine

Nothing indicates that you can get 240 volts from the Predator. Buy a transformer or an inverter capable for 240.

Fuse? If fine then open up unit and check components. First for anything spotted visually like burnt/shorted components and any solder cracks on the board from heat.

can not find much here but it seems like the air filter is pluged

Hi, here is the error codes that I could find for you, it seems you are overloading the inverter. That means you cannot connect a kettle or other heavy load to the output. See all error codes below, hoep this helps.

Problem: The AC load will not operate, error code shows on digital
display and alarm is sounding.
Error Possible Cause Solution
E01 Low voltage shutdown because battery is discharged.
Recharge battery. Shorten cables or use heavier cables.
E02 Over-voltage shutdown because of high input voltage.
Verify the charging system is properly regulated and the battery
is 12 V nominal.
E03 The AC product(s) connected are rated at more than the
inverter's continuous power rating; overload shutdown has
occurred. Use a product with a power rating within the inverter's continuous power rating (see Table 3).
E04 The inverter has overheated due to poor ventilation.
Overheating shutdown has occurred.Turn inverter off and allow to cool for 15 minutes. Clear blocked fan or remove objects covering unit. Move the inverter to a cooler place. Reduce load if continuous
operation is required.
E05 The AC products connected have a surge power that exceeds
the Digital Inverter's surge capability or the AC products connected are short-circuited and shutdown has occurred.The products exceed the inverter's surge capability. Use a product with a starting surge power within the Digital Inverter's capability.

sir plz answer me my ac orien 1 ton showing EC error on display what is this i can't understand what is this plz reply

Hi
Is the code OCP?
If it is not the code appearing in the display, then it is not a user code but O does refer to an over tollerance situation and L refers to an under tollerance situation can you clarify?

bought Traileye XP......already has code entered so total waste of money!!!!

Late Four Digit Ford Radio Codes (no SELECT button) ie. Ford 3000 Traffic, 4000RDS, 5000RDS, 6000RDS, 6006E, etc Switch the radio on and the word CODE should appear in the display Repeatedly press button 1 until the correct first digit of the code is displayed.
Repeatedly press button 2 until the correct second digit of the code is displayed.
Repeatedly press button 3 until the correct third digit of the code is displayed.
Repeatedly press button 4 until the correct fourth digit of the code is displayed.
Once the code has been correctly selected on the radio's display, press button 5 to enter. If "LOCK 10" is shown on the display, please contact us for guidance. If the display shows "LOCK 13" code entry will not be possible, and the unit will need to be electronically decoded by a car radio servicing specialist. Early Four Digit Ford Radio Codes (units with SELECT button) ie. Ford 2005, 2006, 2015, etc Switch the radio on and the word CODE should appear in the display. If CODE does not appear immediately, press the SELECT button momentarily, and CODE should then appear on the display. Repeatedly press button 1 until the correct first digit of the code is displayed.
Repeatedly press button 2 until the correct second digit of the code is displayed.
Repeatedly press button 3 until the correct third digit of the code is displayed.
Repeatedly press button 4 until the correct fourth digit of the code is displayed.
Once the code has been correctly selected on the radio's display, press the "SELECT" button to enter. Three Digit Ford Radio Codes ie. Ford 2000, 2001, 2005, 2007, etc Switch the radio on and the word CODE followed by three dashes should appear in the display. These three dashes should be flashing. Enter the three digit code by repeatedly pressing station presets 1-3 until each digit is correctly displayed, followed by preset 4 to accept the code. The unit should then function normally. If, after switching the radio on, the three dashes do not flash, then 3 or more incorrect code entries have been attempted. If a number 10 appears in the display, then ten incorrect codes have been tried and the unit will need to be decoded by a car radio servicing specialist.
