Hello All,
I am designing a generation unit where a 12V automotive alternator will be coupled to a small engine. Exact efficiency losses unknown, I have a 30 to 35 amp load. The load will be drawing from a 12V battery and the battery will be recharged during the draw by the alternator. The alternator is rated (40A).
Being that my load is potentially 35Amps...would I be o.k. using a 40Amp alternator? Or should I go with something like a 50 or 55 amp?
Is there any general good practice or rule when selecting sufficient compensation such as this? I am not sure what my frictional or resistance losses are. Thanks,
