Some inverters will not work plugged into a standard lighter port. I had to wire an outlet direct from the battery, using #6 wire and a 30 amp fuse and all has been fine.

How do I fix or reset my inverter?


Low input voltage or current.
Bad input voltage sensor.
Test by connecting directly to battery (with jumpers or make an adapter). The wiring or connection to your power port (cigar lighter) may be bad.

If it works at the battery, it is the car wiring. If not, it will cost more than the 25 dollar price tag to have it repaired. Just replace it (tryhttp://search.harborfreight.com/cpisearch/web/search.do?keyword=inverter )

Hi as I'm a girl and know very little information about inverters,I would like to power my freezer and microwave,so could someone please help me and tell me which one would work for me.thanks Sarah


find the watts on each appliance. Usually on the back of then. Add all the watts together then buy a inverter that can put out more than what you need. Say all the watts come up to 2,000watts you will need an inverter that's 2,500watts minimum so you don't burn up the inverter.

I have a 1250 watts inverter and i wanted to know if i can connect it to my 2003 ford explorer without connecting it straight to the battery


Let us look at the math. 1250 watts at 120 volts is w=va Watts equals volts times amps. Or in this case 1250 divided by 120 volts = 10.41 amps. But what is the 12 volt side capable of drawing. 1250 watts divided by 12 volts. 104.10 amps. This is more than what the average cigarette lighter or power port can provide. So, yes you need to connect directly to the battery, you can use a relay rated for 100 A in between the inverter and battery to control the power to the inverter. I would use a good #2 copper welding cable for the power leads. Now, if you are not planning on using the whole 1250 watts, then you can use a #4 welding cable (it is very flexible) for power leads.

Will not turn on


sounds to me like there is a dead short somewhere in the system, I would take it to an electrical appliance repair shop and they can fix it. If there are none in your town then look on the internet for one in your state so you won't have to send it very far to get it fixed.

After I hook up the power inverter to the battery, the AC product does not operate and/or the red FAULT light comes on.


It would depend on what type of AC product you'r trying t operate. While your load maybe only 1,000 watts, the starting inrush current may be too much for your inverter. Try turning inverter on, and see if it powers up. Try pluggin in something very small. Another possibility is the 12V circuit you're plugging the unit into isn't large enough to carry the current, and the incoming voltage is dropping too low for the unit to operate. A 1000 watt inverter is too large to plug into your cigeratte lighter unless you're only operating a very small load. Usually they are connected right to the battery. If you do this be sure to fuse it there , and run large enough wire to the inverter. You should probably have about a #4-#6 copper wire for such a large inverter.

Trips out even with low load. battery voltage is good


you must know the given maximum watts of the inverter.Let me say its especification is a 500 watts:
You must have a load of not exceeding a 500 watts becos it will surely trip or the inverter might be burned.So,if you said you have a low load,be sure that the load you inter is lower than the given wattage of your inverter.Ifd you have a question,just give me a message so that i could help.

Overloaded my inverter -now only works when hooked to car battery


It sounds like the fuse that protects you cigarette lighter is blown.

After you have replaced the fuse, check the voltage again. 0.015vdc would not have powered anything that in manufactured to operate on 12vdc.

When powering anything over about 250W, I would suggest connecting directly to the battery to avoid overloading the lighter circuit.

Why does the power inverter keep beeping when i plug up my laptop


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.

Hi, i've got a skytronic 300w soft start inverter making loud beep and then cutting out. I know its one of the safety cut outs but not which one. can it be repaired ? thanks


If your appliance draws over 300W or if your 12 v battery charge is low you will get a loud beep warning. Do you get the same beep with a low current appliance like a lamp? Make sure your battery has a good charge.

Some appliances have huge draw at start up even though they are rated under 300w your inverter may not be able to start.

Also some electric motors don't like modified sign wave inverters.
What are you trying to run and what is its rated watts?

I had my inverter beep when I had it connected via a cigarette lighter plug but when I used a connection straight to the battery it worked fine.
I was running a 500w grinder on a 1000w el cheepo inverter.
