What kind of alterator do i need for a 3000 watt system

And you need 3000 watt hours 3 kWh of battery for each hour of run time. So basic 50-watt headlamps are only going to pull maybe 4A 50W.

What kind of alterator do i need for a 3000 watt system. Ad MAXX Output High Performance Lifetime Warranty Free Shipping. 3000 watts 12V 250A. Youd need a 250A alternator to keep up with it.

Youd also need a much fuel tank since your engine would have to work just as hard as any portable 3KW generator to keep up with the amp. Battery could would depend upon how often how long you want to run this amp without the engine running. Click to see full answer.

What Size Alternator Do You Need for Your Car Audio. It depends on the total energy required for your cars system. An as usual amp needs by the all electrical system of a general car supposed to be- Headlight -10A Car radio-10AAC -20ADefroster -15ATotal 55A.

This 55A power you can get easily from your inbuilt car alternator. No you dont need an isolator. Stock vehicle electricals can normally support 1200-1500 watts.

How many real world amps it draws will depend on your box rise. Get a voltmeter and see what you are charging at and add electrical upgrades as needed. You can go big 3 and alternator or big 3 and AGM battery.

Amps x Volts Watts Watts 7457 Electrical Horsepower Produced Electrical HP X 25 25 Efficiency Loss Horsepower Lost Electrical HP Produced HP Lost Total Horsepower Used. Lets apply the formula to an alternator that produces 57 amps at 149 volts. 57 x 149 8493 Watts 84937453 114 Electrical Horsepower Produced.

The alternator generates enough amperage to meet the needs of the combined electrical system at any given time and then each component draws its share. In order to determine how much amperage a component is going to draw you can divide its wattage by the voltage of the system. So basic 50-watt headlamps are only going to pull maybe 4A 50W.

Now with a dual alternator set up you will combine your stock alt to at your High Output alt me personally i would get the biggest one you could fit370 hairpin just for the fact you will idel with great power. And if you need some more you have plenty of reserve. 3000 watts 12V 250A.

Youd need a 250A alternator to keep up with it. Youd also need a much fuel tank since your engine would have to work just as. If you can not find the wattage on the devices nameplates then use the amperage of the devices.

I WE Amps WattsVolts. 3000120 25 amps. A total of 25 amps can be used from a 3000 watt.

What you really need is two amps. One that is 4 channel and one that is 2 channel. If they all have the same power output at 2ohms you should have the same volume across all the speakers.

I would look at the Alpine line. They make some nice amps. There are several things you can do to increase the performance of your electrical system.

First you can replace the stock alternator with a high-output alternator the single most important modification you can make. There are many high-output alternators on the market. For 1500 watts you would need XXX amount of leftover amps for your system.

1500 watts divided by 12 volts at idle because it is safer this way instead of 138 or 144 125 amps. 1500 12 125 Now multiply 125 amps by 12 efficiency factor for class D amps or 14 for class AB amps. 125 X 12 150 class D 125 X 14 175 class AB.

In an ideal system your 3000 watt inverter will power 3000 watts of load. And you need 3000 watt hours 3 kWh of battery for each hour of run time. Of course it doesnt work quite that well due to inefficiencies and duty cycle limitations but this is the basic idea.

Now if you do need a new and larger alternator after finding the stock rating then allow your alternator about 10 Amperes credit or buffer area. As a note when calculating your required current for your audio system this is an easy way to do it. 10 AWG battery cables should be used on power inverters rated up to 3500 watts and most commonly used on 2000 2200 2500 3000 3300 and 3500 watt inverters.

You can find our 10 AWG cables here on IRU and on Amazon. We have 200A and 300A ANL fuses and fuse kits available for use with 10 AWG cables. You can find them on IRU and Amazon as well.

Ben Hartley wrote a great lengthy answer. In order for you to pull 3000 watts through that inverter you would need something like 2 full sized automotive batteries designed for large vehicles. As another writer stated a 3000 watt inverter is very likely too big for your needs.

I will assume you already have the solar panels and the inverter. What size battery do I need for a 3000 watt amp Answered By. Sep 21 2021 250 amp alt stock battery and a Good Group 31 Powermaster 3100 kinekit 2400 or 3800 Shuriken BT-120 will keep you good with a 3000 watt amp.

You can figure out the amperage draw of your system using Ohms Law to determine how much capacity youll need. I current P power in wattage divided by E power in voltage Lets say youve got one 2000 watt amp like the q1-22002 and a 1000 watt multiple channel amplifier like the Q4-150. Your alternator is rated at 144 volts.

Now that we know what two of the three values are we can solve for the third value. Understanding the needs of your system can help you know when to choose 4-gauge wire instead of 8-gauge wire. Do a little bit of math and then consult our wire size chart below.

Of course if youre looking for a new car amplifier we list the recommended amp wiring kit with each amp. The formulas for calculating current draw. Lets use E to represent this unit.

E represents the energy stored in a battery which is also expressed in watt-hours. Input Numbers Into a Battery Amp Hour Calculator or the Formula Below. The calculator will use this formula to determine the amp hours.

You can always opt to do the math yourself. E V Q. Q amp hours E V.

When using only one battery refer to the Primary column. When using a second battery as a supplemental battery refer to the Secondary column. When replacing the original battery and adding supplemental power use a combination of the two columns to arrive at the desired level of power needed to satisfy any stereo system.

Lets look at a specific example. If you have a mono block and a 4-channel amplifier that each are rated at and outputting 500-watts RMS power you have a total of 1000-watts. Your alternator is rated at 144 volts so the resulting calculation for current amps would be I 1000144.

The result is 6944 amps. Ad MAXX Output High Performance Lifetime Warranty Free Shipping.
