Here are some more of the details. My previous posting describing the portable power hydro system I built seems to have been taken off or lost. But anyway, I built a portable power system out of an trolling motor to take camping. It works great, but the only problem is it normally produces 5 VDC power at most, and I need 12DC for the inverter. In some cases it produces power as low as 2 or 3 volts. So to sum it up:
INPUT VOLATE: 2-5 VOLTS DC
OUTPUT VOLTAGE: 10 - 14 VOLTS DC (12 NOMINAL)
WATTS USED: 350 SURGE, 30-50 NORMALLY.
WATTS GENERATED: This is hard to say since they rate trolling motors in lbs of thrust. The one I used is 30lbs of thrust. I could not measure the amps because my multimeter is not good enough. At 3 volts I would estimate at least 100 watts, a 4 or 5 volts its really cooking and has lot of power. Easly 100s of watts could even be over 1000.
