## 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).

## How many amps do I need for 5000 watts?

It may be that you have a circuit drawing 500 amps at 10 volts (500*10 = 5000 watts). Or you may have a circuit drawing 10 amps at 500 volts….How many amps does 5000 watts equal?PowerCurrentVoltage200 Watts1.667 Amps120 Volts3 more rows•Jul 1, 2020

## What size of 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 much power does it take to produce 100 amps from an alternator?

about 4 HPAn alternator typically takes about 1 HP (horse power) for every 25 amps of power generated. So, a 100 amp alternator will require about 4 HP at full output.

## Can a car alternator power a house?

First of all you need a steady source of rotational power in your home to turn the generator. If you don’t have that you are no-go. An alternator will put out perhaps 20–50 amps at 14 volts… that’s about 600 watts or so. … An alternator will put out perhaps 20–50 amps at 14 volts… that’s about 600 watts or so.

## How many amps should a 12 volt alternator put out?

Most automotive batteries are lead acid 12-volt DC (Direct Current). Each of the six cells in a 12-volt DC battery produces 2 to 2.1 volts. When the engine is running, the alternator will typically put out between 13.8 to 14.8 volts.

## How many batteries are needed for a 2000 watt inverter?

two batteriesTypically two batteries are needed for a 2,000 watt inverter like the part # 34278156 that you referenced.

## How many watts is an amp hour?

The key is to use the watts you know to calculate the amps at the battery voltage . For example, say you want to run a 250 watt 110VAC light bulb from an inverter for 5 hours. Amp-hours (at 12 volts) = watt-hours / 12 volts = 1470 / 12 = 122.5 amp-hours.

## 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 many 12 volt batteries can you run in parallel?

Technically, there’s no limit, but there is at least one caveat… No two batteries will have EXACTLY the same terminal voltages. That means, even for two batteries hardwired together, the slightly higher-voltage one will end up ‘charging’ the slightly lower voltage one.

## How many watts is 30 amps?

7,200 watts30-amp 240-volt circuit: 30 amps x 240 volts = 7,200 watts. 40-amp 240-volt circuit: 40 amps x 240 volts = 9,600 watts.

## What is the most powerful alternator?

— Remy International Inc., manufacturer and distributor of Delco Remy brand heavy-duty starters and alternators, has released its most powerful and efficient alternator yet to the aftermarket. The Delco Remy 55SI has a durable brushless design and is rated at 420 amps at 12 volts and up to 275 amps at 24 volts.

## What size alternator do I need for 3000 watts?

3000 watts / 12V = 250A. You’d need a 250A alternator to keep up with it. You’d 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.

## What is the difference between a marine alternator and a car alternator?

Industrial alternator applications require continuous-duty, high-output alternators built to last while operating safely. … This means that marine alternators must be self-cooling at high loads or have an additional cooling subsystem. Marine alternators also comply with strict safety specifications not required of cars.

## Will my amp kill my alternator?

Registered. Regardless of how big of amps you have, if you are listening to it without the car running, its going to draw alot of power, and it will kill your battery. Eventually, it will kill it to where it wont recharge. Your alternator strains greatly when you try to charge a dead battery with it as well.

## How many 12v batteries are needed to power a house?

Number of Batteries A battery bank designed to power an average American household for three days would need to supply 90 kilowatt-hours of energy. The battery from the previous example can supply 2.4 kilowatt-hours, so this system would need 38 batteries.

## 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. The limiting issue here is the low system voltage requires very high amperage to get high power. High amperage requires very large conductors (wires), which is limiting.

## 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.

## Is a 160 amp alternator good?

The high amp alternator will give you more replacement juice if you are running any high amp load appliances. The 160 amp is known to be used on emergency vehicles that are at a standstill and still running lots of 12v power thru said appliances.
