Lagat "], "item_description" : "Running a tiny home, a cabin, an RV, or a boat entirely on sunlight is not a leap of faith. It is a design problem with a correct answer, and most guides never actually show you how to find it. This book does: a complete, chapter by chapter method for sizing, wiring, building, and living on a system you designed yourself, with every formula worked through on one real cabin build, from the first panel to the finished, commissioned circuit.The book unfolds in six parts, each one building directly on the last.Part One lays the electrical foundation every later chapter depends on, the handful of relationships between volts, amps, watts, and watt hours that make every calculation afterward possible, explained for a reader who has never wired anything before.Part Two turns a stack of appliances into a single, honest daily energy number, the load inventory and efficiency margin method this book uses to size everything that comes after it.Part Three covers solar arrays and charge controllers: how panels are wired together, how MPPT and PWM controllers actually differ, and how to size a controller correctly for a given array.Part Four is a full battery education, chemistry, lithium iron phosphate in particular, battery management systems, and the two formulas that size any battery bank to any number of days of autonomy a reader chooses.Part Five, Wiring, Power Conversion, and Protection, is where a system stops being a parts list and becomes a safe, code conscious installation: wire sized to the ampere, an inverter sized to the load, and overcurrent protection placed exactly where it belongs.Part Six, Building and Living Off Grid, carries a reader through grounding and bonding, generator and alternator backup charging, a full build day commissioning sequence, and four complete real-world systems, a tiny home, a camper van, and a sailboat alongside the cabin, proving the method travels well beyond a single example.Every chapter follows the same practical structure: full prose instruction, a worked formula, a diagram, practice problems, and an answer key, so a reader can check their own understanding before ever picking up a tool.Inside you will discover: How to size a battery bank to any number of days of autonomy using two formulas that work for any system, from a weekend cabin to a full-time tiny homeThe real difference between MPPT and PWM charge controllers, and how to size either one correctly for a given solar arrayA complete wire gauge and overcurrent protection method that scales from a single battery to a full house bank, with every number explained rather than handed down as a ruleA full build day commissioning sequence that catches a wiring mistake while it is still easy to fix, rather than after a system is sealed up and switched onFour complete, real world system designs, a tiny home, a camper van, a sailboat, and the cabin that runs through the whole book, so you can find the one closest to your own build and adjust from thereWhether you are weeks from ordering your first battery or already mid build and stuck on a reading that will not make sense, this book was written to meet you exactly where you are. Scroll up and start building a system you understand from the panel to the plug.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/9/79/816/212/9798162127833_b.jpg", "price_data" : { "retail_price" : "24.95", "online_price" : "24.95", "our_price" : "24.95", "club_price" : "24.95", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
