Inverter

[Wilhelmus Schreurs]

Ok, let me explain:
there is a battery bank which has a certain capacity.
there is an alternator which has a predetermined charging capacity

You are correct that the alternator charges the batteries.

BUT the alternator is only so big, 160 amp so that gives you 1920 watts each
hour.
The battery bank has capacity depending on the size.

The question Don wanted to know is if he can use some of the 120 volt electrical
equipment while driving down the road.

So, you have an alternator going which can produce up to 1920 watts. With this
setup, the appliance is taking power out of the battery bank through the
inverter, while the alternator is trying to replace what has been removed. But
while you drive, there are other things which is taking load as well, things as
lights, if you have an electric retarder, stereo, and many other things. All of
this comes into play with the load on the alternator. If you draw more load
than what your alternator can produce, then the difference is coming from the
batteries. If you run long enough like this, well it certainly is not good for
the alternator, but the batteries will become depleted, then the only other
thing which would help is to start the generator, the generator would take the
120 volt loads, which includes the inverter, thus helping to restore the
batteries to normal.

Hope this helps.

Wilhelmus:



I am certainly not an expert on inverters but I am having trouble

following your logic. You seem to be confusing 12 volts DC with 120 ac.

I would think that the first factor would be the capacity of your

battery bank. The alternator is not providing the power to the

appliance it is charging the batteries. The inverter is converting the

12v dc fom the batteries. Perhaps one of the electrical gurus will

provide an expanation. I will gladly eat crow if I am wrong.
