EP-181: Sailing with Solar: Lithium Battery Conversions and Off-Grid Power with Charlie Kirchofer

In this episode of the Sailing and Cruising the East Coast of the United States podcast , hosts Bela Musits and Mike Wasserman are joined by recurring guest Charlie Kirchofer to dive deep into the world of marine solar power and lithium-ion battery conversions. For many sailors, moving toward a more sustainable and independent power system is a significant undertaking that is often "harder than it sounds". Charlie shares his firsthand experience as he prepares to overhaul his boat’s electrical systems to achieve true off-grid freedom. The conversation begins with the practical reasons behind this major project. Charlie explains that his primary motivation was a simple, everyday convenience: the refrigerator. Because his boat is kept on a mooring without access to shore power, he previously had to turn off the fridge and empty it every time he left the boat. By installing solar panels and lithium batteries, he can finally keep his fridge running 24/7, allowing him to leave condiments and cold drinks on board for the next weekend’s sail. A major catalyst for this transition was the consistent failure of his existing generator. Charlie recounts the frustrations of dealing with an over-engineered Fisher Panda generator that suffered from chronic electronic issues and poor customer service. Between the difficulty of finding qualified technicians and the literal "headaches" of maintaining a noisy, sound-insulated diesel engine, Charlie decided it was time to move away from fossil-fuel-dependent power. The episode also covers the technical aspects of a marine solar installation. Charlie discusses the "three components" of his new system: flexible solar panels mounted on the bimini, a lithium-ion battery bank, and a high-output alternator. He shares his thought process on why he chose flexible panels over rigid ones to maximize "real estate" on his bimini without cluttering the deck. Listeners will gain valuable insights into the math required to ensure a solar array can handle constant loads like refrigeration and bilge pumps while keeping the batteries topped up. Whether you are looking to ditch a problematic generator or simply want to keep your beer cold without shore power, this episode provides a realistic look at the research, decision-making, and organization required for a successful solar conversion.
