Off-Grid Power Systems for Tiny Houses

Living in 200 square feet presents unique energy challenges. You have limited roof space for solar and no room for noisy generators. In this architectural engineering guide, we explore why 48V is the only logical voltage for Tiny Homes, the feasibility of induction cooking on battery power, and how to manage the "Winter Energy Gap" in a micro-dwelling.
