Micro Hydro Turbine
The Micro Hydro Turbine system outputs around 60-110 W all day long. We currently don't have any accurate information on its original efficiency, head, or other characteristics. Please update this section and the micro-hydro page if you know more.
Maintenance
You have to flash the magnetic field of the generator if it looses its magnetic field. Residual magnetism in the generator exciter field allows the generator to build up voltage during start-up. This magnetism is sometimes lost due to shelf time or improper operation, among other reasons. Restoring this residual magnetism is possible and is sometimes referred to as "flashing the exciter field". 1
Furthermore, we could get a flashing module to automatically flash the generator. Another option is to use a drill to excite the magnetic field again.2
