# Question: How Big Of An Alternator Do I Need For 3000 Watts?

## How many batteries is 5000 watts?

The number of batteries will depend on the DC input requirement of the inverter.

Usually, a 5kW inverter will have a 24v DC input requirement.

So you will need two 12v batteries.

Some models use 48V DC, in which case you will need four 12V batteries..

## How many watts does a 200 amp alternator produce?

2880 wattsA large alternator can be 200 amps or more. 14.4 volts x 200 amps = 2880 watts.

## Will a capacitor help my alternator?

Capacitors will not make up for an inadequate power source. They WILL filter the power, providing a cleaner power flow to the amps, as well as filtering the draw from the battery & alternator.

## How many watts can a 120 amp alternator handle?

1200 wattsThe other sorta relative rule of thumb is that 10 amps can translate to somewhere in the neighborhood of 100 watts… so a 120 amp alternator could do 1200 watts.

## How many amps is 2000 watts alternator?

The easiest way to ballpark that figure is to use the formula amps x volts = watts. For example, if you installed a 2,000-watt amp, assuming a nominal voltage of 13.5V, you’d add roughly 150 amps of demand to the electrical system.

## Can an alternator be too powerful?

You can never have too much amperage when it comes to alternators; therefore, you never have to worry about choosing an alternator with too high of a rated output. Here’s why: Amperage is basically the amount of electrical current your alternator can supply. And it basically operates off of supply and demand.

## How big of an alternator do I need for 5000 watts?

It’s going to consume 7142 watts to create that 5000 watts. 7142 / 14.4 = 496a. You will need 532 amps of alt to sustain this amp constantly while running the car and a few accessories.

## How many watts can my alternator handle?

at a charging voltage of around 14 Volts that yields in 560 to 770 Watts. In modern cars alternators have outputs between 70 and 180 Amps! especially when catalytic converter systems with heating elements etc are used. Sometimes alternators are water cooled as well (BMW 150 Amps).

## What size alternator do I need?

As a rule of thumb, 12-volt alternators use one horsepower for every 25 amps of output, or to put it another way, their ratio of output to horsepower load is 25:1. So, when selecting a new alternator, you need to size it for the limits of the capacity of its drive belt.

## How many watts does a 300 amp alternator produce?

But nowadays, a single alternator can produce power up to 2500 Watt, depending on the power demand. The power that can be produced by an alternator is determined by the alternator rating. The output of the alternator ranges from 40 Amp up to 120 Amp. For high-amp alternator, it can generate up to 300 Amp.

## Can a sound system kill your alternator?

OP: yes your charging system can be permanently damaged if your system is too ‘badass’ also running the system with the car off (especially) for a long time can cause the life of the battery to be severely shortened and cause the alternator to have to re-charge a drained battery which is wasnt designed for.

## How many volts should my alternator be putting out?

13 voltsThe voltage should read a minimum of 13 volts. A good alternator should put out between **13.5-14.5 volts. Stress test the alternator – Place a load on the alternator by turning on the headlights, the radio and the air conditioning. The voltage should remain high with these circuits on.
