The Watter Buddy is a small package water turbine generator designed by Energy Systems & Designs, capable of generating DC power from a running water source. The system can be used with water systems such as the city water supplying systems which are under a certain pressure as well. The manufacturing facility is situated in Waterford, Canada.

Number of nozzles
1 to 4 nozzles
The system has two models 12/24 or 48/120 volts. The output power of the device is up to 200 W. It is small and weighs only 3.6 kg. The number of nozzles can range from 1 to 4. Brass nozzles are supplied with the device from 3 mm up to 7 mm in size. For higher head applications smaller nozzles can be used and for lower head applications larger size nozzles can be used.

The manufacturers in Canada may provide technical support. Local electricians or plumbers may be of assistance but it is possible that they are not familiar with this specific technology. Additionally, the manufacturer provides a user manual, which offers advice on measuring flow rate, determining head, and guiding the installation of the system, although the directions are fairly complex and require some technical expertise. Not all parts necessary for a complete system are included in the kit

Manufacturer Specified Performance Parameters
Vetted Performance Status
Varying water flow rates can cause an increase in voltage beyond battery rated capacity (potentially lethal), improper installation can lead to electrical fires.
Complementary Technical Systems
Additional components can be purchased by sending a direct inquiry regarding additions to the water buddy system.
