The dynamo gives out 6-140volts I want to charge a 12v battery bank using a water wheel. I'm used to solar power, the controllers only go up to 50v.
The dynamo will be connected directly to the water wheel in an operating system.Is the dynamo connected to the water wheel in an operating system ?
Is the 6- 140 V DC ?
What is power rating of dynamo ?
What is Ahr. rating of the battery bank ?
Have you ever tried varying the field current to see the effect on output V ?
The control might be = or similar to an older 12 automotive alternator regulator.
I know nothing about water powered dynamos.
The water wheel will be 2"diaHow many rpm do you need to get 140V from the dynamo? What size water wheel? What water flow rate?
The water wheel will be two feet diameter
Below is a link to the dynamo which will be connected directly to the water wheel.

I do not know the water flow all I can say is its moderate.
Even if the wheel is 2 feet diameter I share your doubts, Les. Maybe if the wheel is positiond at the foot of Niagara Falls it would work .I do not believe that your 2 inch diameter water wheel will turn this motor with it's 240:1 step up (When used as a generator.) gearbox.
Thankyou for all your repliesFrom "Producing Your Own Power", Net horsepower available at turbine shaft = ( cubic ft./ sec. X gross head in ft.) / 8.8 . You would need about 2 HP or better for 1 kW DC output.
A 2 ft. dia. wheel seems fine depending on type & head.
What head of water is available?it is an under driven water wheel
Hi yes it is a under driven wheel floating on a catamaran.What head of water is available?
