Microhydro generator for smallscale hydroelectric power generation. Compact turbine and generator assembly designed for low water pressure start and continuous lowflow operation. Suitable for lighting, charging small batteries, and powering small 5V or 12V devices. Key benefits Low water pressure startup: starts at 0.05 MPa, allowing use with small streams and low head installations. Efficient power conversion: enlarged vortex impeller and dual magnetic circuit coupling improve generation efficiency while added bearings reduce wear. Water and electricity separation: internal water and electricity separation design reduces direct contact and isolates the electrical components from the waterway. Durable construction: stainless steel machine wire screws and iron shaft provide mechanical strength for longer service life. Easy plumbing connection: inlet and outlet use four point external screw threads with an outer diameter of about 20 mm for straightforward hose or pipe fitting. Flexible output options: available as DC 080V, regulated DC 5V, or regulated DC 12V to suit different charging and power needs. Technical specifications Measured output peak voltage: 12 V Measured output peak current: 220 mA at 12 V Line to line resistance: 10.5 +/ 0.5 ohm Insulation resistance: 10 megaohm (measured with DC 100 megaohmmeter) Outlet closed peak withstand pressure: 0.6 MPa Outlet opening peak withstand pressure: 1.2 MPa Starting water pressure: 0.05 MPa Terminal: 2pin Shaft material: iron Screws: stainless steel machine wire screws Magnet: strength boron magnet Mounting base: not included Installation method: assembly required Model number: DC Micro Hydro Generator Type: water generator Model and output descriptions DC 080V variant: unregulated DC output up to a peak near 80 V. No internal voltage regulator. Can directly power 3 V to 12 V LED lights around 10 W, or directly charge small batteries. Charging peak current is approximately 220 mA. When charging a small battery the system voltage will typically stabilize near 14 V while charging, allowing continuous transfer of generated energy to the battery. DC 5V regulated variant: provides stable DC 5 V output suitable for charging mobile devices and lithium batteries that include their own charge management circuits. DC 12V regulated variant: provides stable DC 12 V output for powering and charging 12 V devices such as radios and LED lighting. Installation and compatibility notes Inlet and outlet use four point external screw teeth, approximately 20 mm outer diameter, compatible with common smalldiameter piping or hose fittings. Twopin terminal for electrical connection. Ensure correct polarity and appropriate charge control when charging batteries. No mounting base included. Product requires simple assembly and mounting to a support structure or housing. Designed for small hydro setups, microhydro experiments, remote lighting, and charging applications where water pressure and flow are limited. Practical use scenarios 1) Offgrid cabin lighting and battery charging: Install the generator in a small stream diversion to charge a small battery bank and run 12 V LED lights and a 12 V radio using the DC 12V regulated model or the 080V variant with appropriate battery charging. 2) Remote monitoring and sensors: Use the regulated 5 V model to supply power to lowpower sensors, microcontrollers, or singleboard computers that require a stable 5 V input. 3) Educational and demonstration setups: Use the unregulated 080V unit for classroom demonstrations of microhydro generation, or to test directdrive LED loads and small battery charging under varying flow conditions. What to expect Suitable for lowhead, lowflow applications where conventional generators are impractical. Requires appropriate wiring, fusing, and battery or load management to match the chosen model and the intended application. Regular inspection and maintenance of bearings, seals, and threaded connections will help maintain performance. This product provides a compact, mechanically robust microhydro solution for smallscale power needs, with multiple output options to match common offgrid and remote power applications.
