SOURCE: Inverter beeps when I plug in extension cord. Nothing else

it is possible the alternator's power is higher than that of the inverter ,that is overload

Most power inverters are strictly single-phase. Meaning true 120V or 240V, and no splitting or duplication. It sounds as if your inverter is a single phase 120V, and likely is not stackable on the AC side.

I recommend looking for a Low Frequency Split Phase power Inverter if you want both 240 and 110 volts.

The correct size of inverter is an easy calculation and important to ensure long life from the inverter and the life of the appliances getting there power from the inverter. To calculate you take the volts and multiply by the amps which equals the wattage. Every appliance has a tag which must state the volts and amps. Locate the tag to find the information. Here is an example.

Under Counter Refrigerator 1.3 amps (120 volts x 1.3 amps = 156 watts)

Microwave (120 volts x 10 amps = 1200 watts)

Alarm Clock Radio (120 volts x .03 amps = 3.6watts)

TV (120 volts x .6 amps = 72 watts)

You now add all the watts together, since the above list could likely be running at the same time. There is a combine wattage of 1431.6 watts. In this example you would need at least a 1500 watt inverter. However given some unknown variables personally I would get a 2500 watt inverter. Less stress on the inverter, will lengthen the life of the inverter. Had the total been 1,000 watts a 1,500 watt inverter would suffice.

You must also remember that your alternator on your vehicle must be able to keep up with the power demand of not only your vehicle needs but your inverter needs as well.

A power inverter is an electronic device that converts electricityfrom one form to another. Power inverters have become more popularrecently as the technology has become more efficient and much moreaffordable.

The most popular use for a power inverter isconverting battery electricity into mains electricity. For exampleconverting your car batteries' 12 volts DC into mains electricity 240Volt AC (Australia) or 110 Volt AC (USA).

WHAT POWER INVERTERS WILL HELP YOU DO

WHAT TO LOOK FOR WHEN BUYING A POWER INVERTER

Apartfrom looking for a good quality well priced product there are a coupleof important elements to consider when selecting your power inverter:

HOW MUCH POWER IS ENOUGH ?

Powerinverters come in a range of power capacities so selecting the rightone for you is very important. Your power inverter needs to be able toprovide sufficient power for the equipment you want to use it with.

Here is a brief check list:

Usingan under-powered power inverter may damage it or the appliance you aretrying to use, so be sure to check the specific wattage requirementsand operating instructions for appliances / tools to be used.

PURE SINE WAVE INVERTERS

Normal mains power is known as Alternating Current (AC) and is a sine wave shape like the black line in the drawing below

Pure sine wave (black) versus modified sine wave (red)

Atypical power inverter produces a 'modified sine wave output' like thered line in the drawing above. While this works for most appliances,light dimmers, variable speed drills, sewing machine speed controls,some laser printers etc. will not operate correctly with a modifiedsine wave power inverter.

Pure sine wave power inverters areespecially designed to provide a more accurate sine wave output and socan be used with these appliances, but unfortunately they are moreexpensive.

Check with your with appliance manufacturer or itsspecifications to confirm if you can use a conventional power inverteror will need a pure sine wave inverter.

WARRANTY

One of thegreat things about electronic equipment is there is no moving parts(although there is a fan in some models) so you can expect a longserviceable life from a power inverter.

STANDARDS

Powerinverters generate dangerous mains voltages so ensure the product youchoose is approved for use with your mains voltage and supplier.

Powerinverters can also generate electro-magnetic radiation that caninterfere with other electronic equipment such as radios transmittersetc. Check for compliance with relevant standards such as C-Tick etc

SAFETY

Powerinverters can generate potentially lethal voltages so the utmost ofcare should be exercised using them to avoid accidental electrocution.

SUMMARY

To select your power inverter carefully check the power requirements for the appliance(s) you intend to use it with.

WHAT POWER INVERTERS WILL HELP YOU DO

- Power inverters enablemains operated electrical equipment to be used even where there is nomains outlets, like in your car, caravan or even on your boat!
- Powerinverters bring creature comforts from home when you go camping orcaravaning allowing you to use your TV, fridge or electric shaver infact most of the normal mains powered conveniences from the home.
- You can charge your laptop in the car even if it doesn't happen tohave a 12 volt adapter. In fact a power inverter can be a very handygadget just to have in your car for those times you need to use a mainspowered appliance while you're away from a power socket.

I can't find an online manual for the model of the appliance you are talking about, so I'm unable to figure out the wattage it draws. Nor do I know where you are in the world and the voltage you are running at, so I can't tell you straight off. But I can tell you how to figure it out very easily:

I imagine that know what your main power supply voltage is (either 240 volt or 110 volt).

You can look at the appliance and there will be a data sticker with the wattage rating on it somewhere (or it will be in the install/Owner manual).

Now you have these 2 bits of information we can do a simple sum:

Watts divided by Volts = Amps

Therefore example calculations look like this:

If you have a 500 watt appliance on a 240 volt system 500/240 = 2.083 so use a 3 amp fuse

An appliance with a 750 watt motor on 240 volts: 750/240 = 3.12 so use a 5 amp fuse

A 2KW (2000 watt) appliance like a hot air blower on a 240 volt system: 2000/240 = 8.33 amps so use a 10 amp (or more commonly 13 amp) fuse

A 500 watt motor on a 110 volt supply 500/110 = 4.5 so use a 5 amp fuse

A 1KW (1000 Watt) appliance at 110 volts: 1000/110 = 9.09 amps so use a 10 amp (or more commonly 13 amp) fuse

etc etc etc.....

If the sum comes out below 13 amps, you can use a 13 amp plug. If it doesn't you need to hardwire it into a proper cooker supply.

inverters run on a square voltage unlike normal 110 runs on a round voltage, the only 2 things that won't run on the inverter is fans and electric blankets

Jul 22, 2011 | Cobra 2500w Power Inverter

If your microwave is wired for 220 volts AC and your country standard house current is 220, and the plug is of the proper configuration, plug it in.

Standard microwave size is around 1100 watts at 110 volts Normally, two times the voltage is 1/2 the wattage. Ohms law, Voltares Law and Watts Law apply.

If your microwave is 1100 watts at 110 volts --- yes you will need a step- down transformer of some type.

it indicates an overload situation

not enough information provided as to voltage supplied to the inverter and the voltage of the grinder

examples are for 110 volts ac with a current draw of 4.2 amps the wattage is 462 watts or for 240 v ac with 4.2 amps the wattage is 1008 watts assuming that it is 240 volts and the inverter has a maximum ate of 1000 watts then it is overloaded and circuit protection is cutting in

check the wattage of the inverter and the wattage of the ac units you use and if there is not a 25% difference in favour of the inverter then it is an overload situation

Question does not seem to match this inverters capability.

INFO:

This Power Inverter converts vehicle’s 12-volt DC power into household 115-volt AC power. AC and USB outlets power and/or recharge personal electronics.

We have owned one of these Power inverters for over a year now and have run a great deal with it, from TV to drill press PC and any thing that was small and that could run from my car. Very nice product.

SET UP: Connect wires. ensure correct polarity, push button on top. Plug in 110 volt appliance.

Hope this tip was of some use.

even the smallest inverter can run a laptop, something is wrong with this unit

I had the same problem with myRm 700, too. Solution : connect your unit into the AC power pack . Turn it on. Then reinsert an address into the unit while plugged into the 110 volt ac wall outlet power supply. You may need to repeat this operation a few times.

Also, used mine in my 18-wheeler using a ac to dc power inverter. It seemed to work everytime. Note make sure the ac to dc inverter you by has enough dc output to feed your Gps all the juice it needs. That ac to dc inverter can be used to run other ac powererd appliances, too.
