The Harris system is an efficient, durable battery-charging pelton turbine. It is especially well suited to produce usable household power from springs and creeks that are too small to sustain the same level of useful power from a conventional AC generating system. Because DC power can be stored, the system is collecting power 24 hours a day, a little at a time, to be used as needed. The average American household (not using electricity to produce heat) requires about 12,000 watt-hours a day, or about 500 watts on a continuous basis. This can be reduced to about 300 watts by just turning lights off when not needed. There are times, however, when as much as 10,000 watts are needed, such as when a refrigerator or vacuum cleaner is started. Because AC systems can not store energy they must be sized to meet this peak load (requiring up to 40 times as much water as a similarly useful DC system). Smaller sized systems save money. DC systems are matched to extract power the way that nature delivers it, slowly and steadily.

They are available with one, two or four nozzles, depending on water flow and power requirements. (PVC manifold with one shut-off valve on two-nozzle machines and 3 shut-off valves on 4-nozzle machines is available). These turbines can be fitted with nozzles up to 1/2" in diameter. Each hydroelectric system is custom-built to match your site specifications. Please tell us your head, flow, pipe size and length, electrical transmission line length and battery voltage when ordering. The new permanent magnet (PM) brushless alternator pictured here is 15-30% more efficient than the automotive alternator used in the past; and they last longer. Allow 5 to 6 weeks for delivery. 1-year warranty.

Multiple nozzle arragnements allow much more water to impact the runner, resulting in greater output at any head, and usable power at a much lower head. All turbines include an ouput-optimizing circuit allowing amximum efficiency at any flow rate. Multi-nozzle systems include PVC penstock and individual ball valves on each nozzle.

The pelton type runner is a lost wax cast of silicon bronze. The wheel is 70 to 90% efficient, depending on the nozzle size and head. The bucket shape allows high efficiency for nozzles and provides a flow range of over 100 to 1. The wheel has a hydraulic diameter of just over 4.0 inches and each wheel is individually balanced.
