Introduction

Welcome to Land House YouTube channel! In this video, I will be showcasing Jay's Micro Hydro System sponsored by Langston's alternative power. If you're interested in Micro Hydro, keep watching as Jay walks us through his impressive setup.

Site Selection

The first step in installing a Micro Hydro System is selecting the right site. Jay chose a location in the mountains of Western North Carolina that provided optimal water pressure for his turbines. The site features a Boulder Field and a convergence of multiple water sources, ensuring a continuous flow of water.

Building a Dam and Coanda Screen

To maximize the efficiency of his system, Jay built a dam using angle iron and tap con to create a backstop for the water pressure and prevent sediment build-up. He also installed a coanda screen to filter out debris and ensure smooth water flow. This investment saves him the hassle of frequently checking and maintaining the system.

Pipe Selection and Installation

Jay opted for a three-inch high-density polyethylene pipe due to its durability, UV resistance, and pressure rating. This pipe runs from the coanda screen to the turbines, covering a distance of 500 feet in two directions. Jay strategically concealed the pipe where it's visible from the driveway by creating a rock Irish knee wall with moss for insulation.

Turbine Setup and Nozzles

Jay's Micro Hydro System features two PMAs (permanent magnet alternators) that serve as turbines. Each turbine is equipped with three quarter-inch nozzles, allowing for a flow rate of approximately 95 gallons per minute. The metal housing of the turbines prevents water splashing and ensures efficient energy conversion.

Electrical System Overview

Moving on to the electrical side, Jay's system utilizes a rectifier to convert AC power generated by the turbines into DC power. This converted power can be either stored in batteries or used directly by the house. Safety measures, such as a DC breaker and a Midnight Solar surge protector, protect the system from lightning strikes and electrical surges.

Battery Storage and Scalability

Jay's Micro Hydro System currently incorporates two lithium-ion phosphate batteries with a total capacity of 400 amp hours. These batteries, connected to the Schneider Connects XW Pro, store excess energy generated by the turbines. To meet increased power demands, Jay plans to add four more batteries in the coming months.

Load Center and Grid Connection

Jay's system includes a load center that manages the distribution of power from the inverter. Since his system is connected to the grid, a grid connection allows the inverter to switch between using turbine power and grid power based on battery levels. The system is also equipped with a battery monitor for real-time battery status updates.

Monitoring and Maintenance

Jay's system is equipped with a power flow monitor that provides insight into the power consumption of his house, as well as the energy production from the turbines. Regular monitoring and maintenance of the system, including checking the batteries and ensuring the integrity of electrical connections, are crucial for optimal performance.

Conclusion

In conclusion, Jay's 850-watt Micro Hydro System is an impressive example of harnessing the power of water to generate electricity. Through careful site selection, dam construction, pipe installation, and turbine setup, Jay has created a sustainable and efficient system for his household. With the ability to scale the system and good maintenance practices, Jay's Micro Hydro System offers long-term energy independence and reduced reliance on the grid.
