500W PMA Power Curve

Power curve is for a 24-Volt battery bank. Therefore, the voltage for the power curve is held steady at around 24 volts.

Power = volts x amps and since you know the volts and power, you can calculate amps at any point on the curve.

The open circuit volts per rpm is about 0.12. For example, 100 rpm is approximately 12 volts and 500 rpm is about 60 volts. As you probably know, batteries clamp the voltage of the generator at their voltage level.
