Depends on several things. 12 foot generates 2.5kw at 23MPH wind. (furled assumed) Lots of power, current depends on battery voltage. 2500w / 56vbat = 44amps, 60amps would be a little shy of what I would use. Lower voltage batteries, the amps go up quickly. 12v battery 178amps!!
Have fun, Scott. [ Parent ]
