Description

Off Grid Solar: The engineering reference for people designing and building reliable systems.Most solar books on Amazon are either RV-weekend overviews or padded with grid-tied chapters you'll never use. This one is built for the person sizing batteries, calculating wire gauge, and choosing between LiFePO4 and lead-acid for a system that has to run every day.Whether you're powering a cabin, a homestead, a tiny home, or a blackout-resilient backup, this book gives you the math behind every decision so you can stop trusting a salesperson and start trusting your own numbers.Inside you'll learn:How to size your panel array against real battery refill needsBattery chemistry compared: LiFePO4, lithium-ion, AGM, flooded lead-acidWhy a Battery Management System is non-negotiable for lithiumHow to size MPPT charge controllers and off-grid invertersOptimal panel angle for your latitude, with the mathWire sizing, fusing, and the right tools for the jobHow photovoltaic cells actually work, without hand-wavingRoof, ground, and pole mounting done correctlyWhat makes this book different:Off-grid only. No filler chapters on grid-tied or net metering. If you're cutting the cord, every page applies.Built for modern systems. Lithium iron phosphate batteries, BMS design, microgrids, and off- grid battery inverters get full treatment.International standards. IEC and globally recognized codes, not just NEC. Useful whether you're in Oakland, Oaxaca, or off-grid in the African rainforest.Solar engineer Joseph P. O'Connor has designed and taught off-grid installations from Bay Area homesteads to remote villages in the Central African rainforest. This is the reference he wishes he had on his first project.If you'd rather understand your system than trust someone else's pitch, this is your manual. Scroll up and click Buy Now to get started.

    • Good starter handbook for RV camper van solar
I found this to be a good primer in preparation for Camper Van electrical design. The book is well-written, and covers basics such as the essentials of energy, power and electrical physics. I should think that for someone with no prior exposure to those basics that this handbook will be a good start if the reader is willing to knuckle down and study what is written. Even for someone who stays intimidated by the subject of electricity and ends up hiring out the work, the book will help them be a more knowledgeable shopper. The book covers: geographic and seasonal available solar energy, battery chemistries, cost of ownership, battery resistance rate of charge and discharge, how to interpret solar panel datasheets, and sizing and derating an overall system. It has both a proper table of contents and an index for reference. The author provides links to some Excel design spreadsheets that are great! It’s a good start, but won’t cover everything I’ll need for camper van electrical design. I very highly recommend supplementing this handbook with an encyclopedia-sized volume: Boatowners Mechanical and Electrical Manual (www.amazon.com/gp/product/0071790330/) It’s written for yacht owners, but will translate well to your land yacht! The author has vast experience with mistakes that lead to common money-wasting pitfalls. What the boat book will do is help the RV / Camper owner integrate alternator charging as a contingency to protect the battery bank during those inevitable days when solar is not sufficient. ... show more

    • Worth the money.
Format: Kindle
What did I like? Easy to understand. Even for someone w/o eletrical background. Great book. Keep up the spread of GOOD and TRUTHFUL INFORMATION. GOD BLESS! J. C. W

    • Good for reference and basic info
Gives a good intro to off grid solar in one place. I've been reading from all over the Internet but info can be a bit confusing so this is handy as a base. From my limited experience so far, it's better to have more panels than you calculate you need because of overcast/cloudy/rainy days (on overcast days I get about 46% of calculated output including accounting for losses from panel to charge controller). Also, better to have batteries with higher AH capacity since it's best to have only 3 parallel strings in a battery bank. ... show more

    • A practical guide for understanding and installing Off Grid Solar systems.
Off Grid Solar is a great starter book for anyone who wants a better understanding of solar energy in general and the potential of "off grid" solar systems specifically. It can also be used as a guide on how to install both the solar panels needed to capture sunlight and the batteries required to store and disperse the retained energy. Joe O'Connor used good analogies to simplify what might otherwise be complex topics to the handyman while providing the science and instructions needed by the electrician or engineer. It's a must read for anyone considering how to move towards personal energy independence with off grid solar energy! Perhaps a better title/subtitle would be something like....Off Grid Solar: a practical guide for understanding and installation. ... show more

    • Good, but keep it real about batteries, please
This is a great primer with a wealth of information, but there is far too much concentration on Lithium-Ion batteries, which might be great for those that can afford them, but for most readers, will be in a fantasy realm in the present moment. The SOC figures for all lead-acid batteries (Flooded, gel, and AGM) are lumped together, which is misleading, and may cause users with AGM batteries to ruin their batteries by letting their SOC dip below 12.7 V. In the real world, folks normally choose between AGM and flooded batteries due to their geographical situation. ... show more

    • Battery Inverter/charger
Format: Paperback
This book helped me to figure out what I really needed and to understand why some inverters seemed so cheap compared to the Outback and Schneider inverters. Not all inverters are battery chargers and inverters in the same package. I also didn't realize I needed one that can do grid sync and power back up loads if the grid goes out.. Lot's of great information, and really clearly written in a way that was easy to follow. Would recommend! ... show more

    • Clear, understandable, and helpful
Format: Kindle
I'm not a technical person, and I had little working knowledge of electricity much less solar power. This book is the first book that was able to explain solar concepts and systems to me to where I could understand them. "Off-grid Solar" is packed with practical advice, e.g., which options work best depending on your objective and budget. Highly recommended. Five stars. ... show more

    • Great little book for my first system. Suggest you couple the guide with further study.
Great little book. Some parts could be a little better explained or complete, but quite comprehensive for such a compact guide. Definitely everything I needed (coupled with a little bit of electrical circuit knowledge of my own) to do my first system successfully.
