If your not getting enough voltage to the inverter it will beep to let you know you don't have enough power. Most common cause is a lose connection thru your cigarette lighter. Also if you turn your key off it might be shutting down power to your plug.
Make sure you have a good connection with your battery or plug adapter. You also need a good battery so you don't go into a low voltage condition which will make your inverter beep.

2. No power supply connecte to the inverter with zero charge in the battery

Kolin inverter fault code E1


Congratulations, your air conditioner has hit 720 hours of use. In an attempt to push people to keep these things extra clean the built-in this annoying feature that spits out an alarm every 720 hours of operation.

Let's reset it and hope that she lasts long enough to give you this error many times to come. :-)

Two ways to get it done:

1) Unplug the machine. Hold down the power button while you plug the machine in and wait for a beep about 5 seconds long. Let go of the power button. Unplug the machine. Plug it back in.

2) Unplug the machine. Hold down the mode button while plugging the machine back in and waiting for a beep of about 3 seconds duration. Let go of the mode button. The machine will start. Turn the machine off by pressing the power button. Resume trying to use the machine normally.

If these don't work, the "demand to clean filter" timer is broken and you will need to buy parts to repair the machine.

I attach my inverter with custom battery cables and it powers up. As soon as I plug in an extension cord (any cord)it starts beeping. I don't even have anything plugged into the other end.


please check the voltage of the battery may be the voltage of battery is low or use the multi meter and check DC volts before conneceting the battery and after conneceting once more check the DC volts it could slove the problem
the beeping sound is due to battery low voltage
what is the DC input of the Inverter check the battery hook up if the inverter is of example DC 24 volts please check what is the input
