This is my direct drive water wheel I put together with some pvc pipe, bike wheels, and hvac sheet metal. After different configurations I am only getting around 18w of power out of it.
The 3 phase BLDC motor is connected to a full bridge rectifier. When I use a solar charge controller connected to a lead acid battery (70% charge 12.2v) the charger says its delivering 1.5amps.
I figured it could make more watts than that, any suggestions?

Try a different generator.
Check out Kris Harbour’s videos about building out a water wheel. He’s making 1000W+ and it’s a very significant dedicated build. https://youtu.be/RWTgMWRc2W4?si=4O2uS7WFES-elNmM
You could try a [‘cross flow’ (Banki) turbine](https://www.pumpfundamentals.com/micro-hydro-banki.htm), or a [Pelton wheel](https://en.wikipedia.org/wiki/Pelton_wheel).
