HOW IT WORKS
The Harris system is an efficient, durable battery-charging pelton turbine. It is designed to produce usable household power from springs and creeks that are too small to sustain the same level of useful power from a conventional A.C. generating system. Because D.C. 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 A.C. systems cannot store energy, they must be sized to meet this peak load (requiring up to 40 times as much water as a similarly useful D.C. system). Smaller sized systems save money. D.C. systems are matched to extract power the way that nature delivers it, slowly and steadily.
A 4-nozzle P.M. Generator-equipped turbine
Multiple nozzle arrangement allows 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 output-optimizing circuit allowing maximum efficience at any flow rate. Multi-nozzle systems include a manifold kit and ball valves for each nozzle.
The 4-nozzle arrangement allows for maximum flow conditions and provides for seasonal flow adjustments.
Pelton Type Runner
The pelton type runner is a lost wax cast of silicon bronze. The wheel is 70 to 90% efficient, depending on nozzle size and head. The bucket shape allows high efficiency for nozzles and provids a flow range of over 100 to 1. The wheel has a hydraulic diameter of just over 4.0 inches and each wheelis individually balanced.
There are two basic system configurations:
Mountain Cabin-DC Direct
The basic system is suitable where battery power can be used directly. Cabins using 12-volt lights, portable radios, televisions, and recreational vehicle type D.C. appliances are easily adapted to the basic system.
Conventional House-110 volt
This configuration is suitable where higher output is needed and 110-volt, 60-cycle A.C. power is required to operate conventional appliances. Both configurations are compatible with other D.C. charging systems of 12, 24,48 volts, including photovoltaic cells, wind charging systems and generator operated battery chargers.
