The dual power system design works well with vehicles like RVs or police surveillance vehicles. Two alternators can also serve as a jerry-rigged replacement for larger alternators by combining two in series to reach the same level of power output, which is particularly helpful in improvised repair situations.
Can you wire two alternators to one battery?
It will work just fine. When your batteries are low both alternators will charge the bank. as they start to top off, one alternator will probably start to ramp down it’s charge rate sooner than the other due to the regulators having small differences.
Do I need a bigger alternator for my sound system?
You might need a bigger alternator for your sound system When it comes to car audio, more power means more sound and vice versa. If you want your music to be big and loud with a huge bass response, you need a big amplifier with a big subwoofer—and a lot of power to run it.
What is a secondary alternator?
A secondary electrical system is simple to understand. In addition to the stock alternator, a high-amp alternator (or multiple high amp alternators), along with suitable voltage regulation controls, is installed on the engine with its output connected to a high capacity, deep cycle battery (or batteries).
Can you run 2 alternators in parallel?
If you connect two alternators in parallel, the two feedback loops will interfere with one another, unless you isolate the two alternator feedback loops by putting one additional rectifier diode per alternator downstream of the feedback loop.
What do dual alternators do?
The two alternator option helps keep the batteries charged when using a lot of electrical power, such as snow plow, or tow truck operation. Both alternators work together as one large one.
How do you connect two alternators in parallel?
The RMS line voltage (terminal voltage) of the bus bar or already running machine and the incoming machine should be the same. The phase angle of the two systems should be equal. The frequency of the two terminal voltages (incoming machine and the bus bar) should be nearly the same.
Should I charge my car audio battery with an alternator?
However, the car audio battery also acts as a second load since the alternator has to keep both batteries charged. As such, consider this option if you run a lot of electronics or play more music when your car is off.
Where is the dual alternator kit made?
Whether you have an EMS, Fire Truck, Paramedic, Police and SWAT vehicles, Shuttle Buses, Car audio, Military and Homeland security we have your back. We are very proud to say, this dual alternator kit is 100% designed and manufactured in the USA!
What does the alternator do in a car?
The alternator charges the battery, which in turn runs all electrical systems. Often, the factory alternator that came with your car is enough to take care of your power needs, but it may not be big enough to accommodate the required power back-up in between bass notes.
What size alternator do I need to run a car stereo?
A good aftermarket alternator should offer between 250 and 300 ampere, which is more than enough current to run both your car system and your stereo too. The easiest way to determine the size of the alternator you need is by establishing the extra amount of power you need on top of the current supply.
