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.
How many amps is A good alternator?
Most factory alternators are rated at 65 to 100 amps and are capable of handling your vehicle’s basic necessities, such as headlights, gauges, fuel pumps, A/C, etc.
How big of an alternator do I need for 2000 watts?
To figure out how much capacity or amperage the alternator must deliver, determine how much extra power the audio system demands on top of the current system. 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.
How many watts does A 150 amp alternator produce?
Sometimes alternators are water cooled as well (BMW 150 Amps). Wattages may vary between 980 and 2520 Watts !
What is the advantage of A higher amp alternator?
That’s because an oversized alternator produces more output at lower speeds, including idle. That increased output prevents the battery from having to help supply the load—and this keeps it at a more ideal state of charge. The battery cycles less, which translates into better battery life.
What size alternator do I need for 3000 watts?
To obtain 3000 Watts AC at 120 Volts from an inverter, you must replace your 100 AMP alternator with an expensive 250 AMP alternator and install MULTIPLE heavy duty batteries. In addition, 50 more amps are required to operate your vehicles accessories, lights, flashers etc.
How many amps does a typical car alternator produce?
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. Commercialized alternator is usually 12 V.
What size alternator do I need for a 1000 watt amp?
As a general rule, you need about 100 amps of current for every 1000 watts of power generated. Add that to the base electrical requirements of your vehicle for the total amount of amp-hours you need for your system. Example: You plan to install a 2,000 watt amplifier.
How many batteries do I need for 5000 watt amp?
You will need at least one 450-500 12V battery or two 210 12V batteries to supply 5000 watts of power for 30-45 minutes. If you’d like an hour of 5000 water of power, you’ll need a 750ah 12V battery.
How many batteries do I need for a 2000 watt amp?
When it comes to batteries, a 2000 watt inverter needs 24 volts to generate power. You would be able to use 100Ah x 24Ah if you used 2 batteries of 12 volts 200Ah.
How many amps does alternator put out at idle?
Typically you can find alternators up to about 100A with the internal regulator and 1-wire output feed, higher than 100A and you need to start looking into a separate stand-alone V-regulator as the heat generated by a high-Amp alternator’s diode bridge and the v-regulator itself would greatly shorten the life of that
How much HP does an alternator draw?
An alternator takes about 1 HP for every 25 Amps of power. At full output, a 100 Amp alternator will need about 4 HP. For a long time, most alternators don’t operate at full output.
Does an alternator make AC or DC?
The output of an alternator is direct current (DC). When the alternator pulley is rotated, alternating current (AC) passes through a magnetic field and an electrical current is generated. This is then converted to DC via the rectifier.
Does an upgraded alternator really make a difference?
A general high output alternator will provide more amperage, and in other words more power, but it will also increase the engine speed, proving itself capable of generating more power, but not being very useful in the long run.
Why do I need a 220 amp alternator?
With a 220A alternator, you can run a large capacity inverter (2kW or greater) while the engine is running. This allows using things like a convection/microwave, or secondary A/C unit.
How many amps does alternator charge battery?
A: Charging time depends on the battery and the charger. For a battery being charged by the car’s alternator it can take an hour of driving to get it fully charged. Car batteries range from 40AH to 110AH, and alternators range from 45 amps to 200 amps.
How many watts can a 270 amp alternator handle?
A typical 12 volt alternator has an operating voltage of around 13.8 volts normally but will likely drop to about 13 volts at peak power. 13 times 270 is 3,510 watts. So we might expect a typical 12 volt, 270 amp alternator to be able to supply around 3,500 watts maximum.
How large of an 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 amp hours do I need for 3000 watt amp?
Most electrical systems need between 60-120 amps to operate, so let’s factor that in too. 3,000 / 14.4= 208 + 120 = 328. For this system, you’d want 328 amp hours of charging power available.
How do I know what amp alternator I need?
Look for a diagram under or near your fuse box cover. It will have individual amperage numbers (sometimes along with volts) already set by the manufacturer. Add up those numbers to find what amperage your alternator needs to feed the car’s electrical system. Verify this number with the part manufacturer, if necessary.
At what RPM does an alternator start charging?
These rpm, along with the pulley ratio, directly affect an alternator’s performance and life expectancy. An alternator has a normal range of operation. Most alternators need to spin at about 2,400 rpm at idle, have their maximum output above 6,000 rpm, and should never exceed 18,000 rpm.
