This means that our machines can be “tuned” so that the output of the generator can be matched to the output of the turbine wheel. At any site, the turbine will generate the most power when operated at the best speed. Our machines (with the exception of the Watter Buddy) have magnet rotors that can be raised and lowered which increases or decreases the magnetic flux. This makes the machine go faster or slower so the best speed can be achieved which is where the highest power is generated. There are electronic devices that can do this. They are called Maximum Power Point Trackers or MPPT’s. These are not required with our machines so there is not only a savings in cost, but these are electronic devices and would be the weakest link in your system. The tuning adjustment would be made when first setting up the machine and then fine tuned at a later date if the flow rate changed.
