Power (P), in Watts, is equal to the Voltage (V), in Volts, multiplied by the Current (I), in Amperes.
P=V*I
Using Algebra to solve for the Current (Amps) that are required:
I=P/V
Therefore: 2000 Watts / 12 Volts = ~167 Amps
Please note, that this is for a 100% efficient inverter. If the inverter is 90% efficient the actual draw would be:
Iideal*(1+(1-(%Efficiency/100)))=Iactual
167 Amps*(1+(1-(90/100)))=Iactual
167 A * (1+(1-0.9))=Iactual
167 A * (1+(0.1))=Iactual
167 A * (1.1)=Iactual
183 A = Iactual
The continuous current draw for a 90% efficient power inverter, operating from a 12V DC source, out putting 2000W at 120V AC, is 183 Amps.

∙ 13y agoAssuming no loss in the circuitry:
Amps * Volts = Watts
Amps * 12 = 400
Amps = 400 / 12
Amps = 33.33333...
BUT
inverts build heat, and that heat wastes electrical energy
Your inverter is probably drawing (at full load) somewhere near 40 amps.

The answer to this question, how many watts are drawn from the battery, is dependant upon what the amperage of the connected load is. A 1000W rated inverter is the maximum amount of connected wattage load that can be used from the inverter. W = A x V.

How many amps does a 5000-watt inverter draw from a 24 volt system?
it draws 210 amps
How many amperes use an electric heater?
The electric heater will have power rated in Watts. The Amps it will draw depends on the voltage system you are using. Can be calculated by formula I (Amps) = P / V In the USA with 110V system a 2400W heater will draw 2400 Watts / 110 Volts = 21.8 Amps In Australia with a 230 V system a 2400W heater will draw 2400 Watts / 230 Volts = 10.4 Amps
How many amps does a 400watt light draw from 220v?
The formula you are looking for is I = W/E.
How many watt power inverter is required to run a 1hp 110v motor?
Need to know the running amp draw. Starting amps would be useful l too. The average amp draw for a simple 1hp motor is about 7 amps, such as a fan motor. Ohms law says amps times voltage = watts, so 7 amp times 120v=840 watts. Consider that starting amperage is about 1-1/2 times running load, starting watts would be about 1200. You would need about a 1200 watt inverter to run that motor.
How many amps does a two-bulb 32 watt 48-inch fluorescent light draw?
draw 0.104 amps
How many amps does a 5000-watt inverter draw from a 24 volt system?
it draws 210 amps
How many amps does a 3000w inverter 240 v draw from a 12 volt system?
It would be at least 250 amps, maybe 300 amps.
Can a 240 watt 2.0amp dc-ac power inverter power a compact fridge?
Answer If, when you state "...240 watt 2.0amp..." you are indicating that 2 amps, or 240 watts at 120 volts, then that inverter will power a device which does NOT draw more than that amount of current. Check the plate or label on the compact fridge you want to power, and find the maximum current draw. For appliances, it will usually be stated in amps, rather than watts. If that amount is equal to or less than the output of your inverter, then it should work. Also, pay attention to the maximum current used by the appliance, versus the continuous output figure for the inverter, NOT the peak momentary output.
How many amps does a sound system use?
amps like.. amplifiers? it depends on how many speakers you have. or amps like.. current draw? again. depends on your power needs, your power amps... ect
If a laptop is powered by twelve volts will a 150 watt inverter work?
Maybe, or maybe not. Depends upon the wattage or amperage draw. At 120 volts and 150 watts, you can draw about 1.2 amps. Probably not enough for a newer laptop, but may power an older one fine. A 300 or 600 watt inverter can be bought on eBay for about 30 bucks.

How many amps does the elecrical system pull on a 2004 jeep grand Cherokee limited?
It all depends upon what is "ON" at the time. A running vehicle with only the ignition system operating uses about 10-15 amps. Turn on the headlights and it will draw an additional 10 amps. With everything on, it can draw from 30-100 amps. Do you mean "what is the alternator rated at?" Your Jeep alternator would be normally rated at about 100 amps output.
How many amps does a 400watt light draw from 220v?
The formula you are looking for is I = W/E.
How big of a power inverter will I need to power a 1000 watt car stereo amplifier amplifier draws roughly 100 amps of power?
You will need a battery charger capable of providing up to75 amps at 12 volts DC. This is called a converter, not an inverter. An inverter takes 12 v and transforms it usually to 120v AC or 220v Ac. Keep in mind that your 1000 watt amp will not draw 100 amps only briefly at times if at all unless you are at maximum volume. You probably could get by with a 50 amp charger and a big capacitor to supply the boost for a few seconds.

Can you power 100volt compressor with 400watt inverter?
It depends on the draw of the compressor.
