There are two basic models which fit two different needs. The stream engine is designed to take advantage of sites with higher head while the LH1000 is designed for sites with low head and high flow. Both models are designed for battery-based power systems, with electricity generated at a steady rate and stored in batteries for later use. When AC power is desired an inverter is used to convert the stored energy. In grid tie applications, the machines are usually used to generate high voltage DC that is compatible with grid tie inverters. Our machines can also feed the utility grid.
Our machines are designed to make use of a natural source of running water. Water from the stream is channelled into a pipeline to gain enough head (vertical drop the water falls) to power the system. The water passes through a nozzle, where it accelerates, strikes the turbine wheel and turns the generator shaft. The amount of power produced will depend on the head and flow from the water source.
Technical jargon broken down to help you understand how it all works.
In order to get started, you will need to determine if your site meets the requirements for generating microhydro power. To do this you will need to measure the head and flow of your water source. Click the link to view a helpful guide on determining these measurements. Once you have measured your head and flow, refer back to the website to find out which product fits your needs.
The LH1000 is specifically designed machine to operate efficiently in low-head sites. It takes advantage of the same generator as the Stream Engine, however the water turbine component uses a low head propeller design.
The 1K Micro Hydro Power System is one of Energy System and Design’s answers to a version of our Stream Engine that can provide reliable power for your needs at an affordable price point.
