ES&D hydroelectric battery chargers use a cast bronze turgo runner to drive a long-life, brushless permanent magnet alternator. A simple change of wiring in the junction box allows the turbine to charge 12,24,or 48-volt battery systems. The turbines come withcut-to-size nozzles that can be user-set for up to 1", allowing a very large flow in low head situations. They can operate on heads as low as five feet with flow of 40 GPM. Head Range: 5to 200 feet. Flow range: 10 to 400 GPM. Maximum Power: 1000 Watts. Voltage is user-set from 12 to 48VDC.
