David Sellers (Hi Off Grid): Designing Off-Grid Energy Systems in Hawaii
In this episode of The Buoy Report Podcast, Shaun Lopez sits down with David Sellers, founder of Hi Off Grid, to discuss what it takes to design and build reliable off-grid energy systems in Hawaii.
David shares practical insights from years of hands-on work — system sizing, battery tradeoffs, maintenance realities, and the common mistakes people make when pursuing energy independence on the islands.
As Hawaii faces rising energy costs, grid instability, and climate-driven disruptions, off-grid systems are becoming a critical resilience strategy — not a fringe choice. This conversation looks at what that shift really means in practice, beyond marketing and theory.
The conversation explores why Hawaii is a unique testbed for off-grid living, how real-world systems differ from marketing promises, and what resilient energy design actually looks like in practice.
