Off Grid Solar: A handbook for Photovoltaics with Lead-Acid or Lithium-Ion batteries

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 needs Battery chemistry compared: LiFePO4, lithium-ion, AGM, flooded lead-acid Why a Battery Management System is non-negotiable for lithium How to size MPPT charge controllers and off-grid inverters Optimal panel angle for your latitude, with the math Wire sizing, fusing, and the right tools for the job How photovoltaic cells actually work, without hand-waving Roof, ground, and pole mounting done correctly What 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.
