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 PowerPal on a small waterfall, dam or diversion trench. Electricity passes along a wire and into a house, where an electronic load controller (supplied) stabilizes the voltage to 110V or 220V to protect electrical appliances during use. 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.
