Also as a stationary power source to charge batteries for off the grid power. But you may be considering a wind driven alternator for off the grid power.

How many amps is a high output alternator?

200 ampsMost high-output alternators provide an output of about 200 amps. Excessive alternator output will kill the battery, but 200 amps is the optimum amount to handle the higher energy demand without killing the battery.

At what RPM does a alternator charge?

Alternator may not generate sufficient charging voltage until alternator speed is greater than about 2000 RPM. Typically, alternators have their full output rated at 6000 RPM but can continue to spin up to 12,000 RPM or more without any additional increase in output.
