Hello,
I have a project that involves the coupling of a 12V Alternator with a small engine to power a loaded 12V battery.
The gas engine is 1.4HP (1043.979Watts) coupled to a 40 Amp 12V alternator which is charging a 12V battery under a 35 Amp load.
The way I see it, the 35 amp load @ 12V = 420 Watts = roughly 0.563HP. Giving the engine an advantage of 623.979 Watts greater than the required draw.
What I do not know is; what the RPM of the alternator is at is most efficient speed. However I am almost positive the engine can meet and exceed it.
Given a basic look at this, do these numbers seem to make enough sense to provide sufficient power for the system to continually work under load? Should I go with a 60A alternator instead? I know there will be losses due to mechanical inefficiency/friction But do these figures seem proportionate enough to actually put to use? What should I look out for?
Any advice greatly appreciated
