How and Why to Design an Off-Grid Electrical System - E-book - ePub

This guide is meant to be a logical, step-by-step manual that describes how to calculate your electrical needs, how to pick a system that works best for you, and how to implement that in an off-grid setting. Although I discuss grid-tied systems, the benefits and pitfalls of wind, micro hydro, and solar-and briefly touch upon the Peltier/Seebeck and piezoelectric effects and heat engines-as well as energy generating methods and storage, this study is mostly concerned with remote power generation.
I discuss how to assess your power needs, how to choose the components which will maximize your ability to use the power generated, and safety concerns when dealing with high-amperage DC systems, electronic components like charge controllers, wiring, and batteries. I also talk about the logic of the system I designed for my needs at the cabin, which is powerful enough to run an electric chain saw, and dependable enough to never leave me in the dark.
Each step on your off-grid energy journey is a logical series of questions which can be answered, and once you design and build the system that suits your needs, then you will have learned a lesson in independence and self-reliance.
