This manual offers important information concerning your new low head micro-hydroelectric generator. It covers models ZD2.0-0.3DCT4-Z, ZD2.5-0.5DCT4-Z, ZD3.0-0.7DCT4-Z and ZD2.5-1.0DCT4-Z. A simple AC single-phase, brushless permanent magnet alternator is attached to a propeller turbine. All or part of the stream flow is diverted into an intake canal where it forms a vortex, causing the propeller to rotate as it exits through a draft tube to flow free again. All that is required is a vertical drop (head) and a sufficient rate of water flow, which are commonly obtained by installing the micro-hydroelectric generator on a small waterfall, dam or diversion trench. Electricity passes along a wire and into a house and an electronic load controller (supplied) stabilizes the voltage to 110V or 220V to protect electrical appliances during use. The generator can also be used to set other voltages such as 120V, 230V or 240V. Being lightweight and portable, installation is very simple and is explained in the Instruction Manual. Once installed there are no running costs and maintenance costs are extremely low.

It is important to keep in mind that output can only be accurately determined if head and flow measurements are made correctly, so care should be taken during this process. Two other important factors in a site assessment are system voltage, and transmission distance. The voltage and distance the power must travel can affect the efficiency and cost of your transmission lines.
