Scott Hydroelectric Turbine Generator
low head, cross flow
suitable for battery-based off-grid system
or battery-less grid tie

Unlike most water turbines which have axial or radial flows, in a cross-flow turbine, water passes through the turbine transversely or across the turbine blades. As with a water wheel, the water is admitted at the turbine's edge. After passing the runner, it leaves on the opposite side. Going through the runner twice provides additional efficiency. When the water leaves the runner, it also helps clean the runner of small debris and pollution. The cross-flow turbine is a low-speed machine that is well suited for locations with low head. 

The Advantages of Cross Flow turbines

Mostly used in Mini and Micro Hydropower production
Ideal for low head conditions as low as 20 feet of vertical drop
The flat efficiency curve yields better annual performance than other turbine systems
Excellent behavior with partial load or low stream flow
Well suited for unattended electricity production.
Its construction makes it easier to maintain than other turbine types
There are only three rotating components
Almost no turbine noise
Self cleaning. No runner cleaning is necessary
No dam required-simple diversion up stream or any water source meeting requirements

AC and DC Cable/wire length and voltage drop must be evaluated carefully when laying out system.  Click here for our simple voltage drop calculator.  If the turbine will be located far from the battery bank and inverter, voltage drop and wire cost can be reduced by locating the ac-to-dc rectifier at the battery end of the transmission line.  The transmission line in this case will be 3 phase ac and will require 3 conductors.
