Field notes from the bench.
How off-grid and marine electrical systems actually work — battery chemistry, system sizing, the standards we build to. Written by the people who do the installs, not a content team.
- Marine
What ABYC E-11 means for your boat's wiring
A plain-language look at the American Boat & Yacht Council's electrical standard for boats — what it requires, why salt and motion make marine wiring harder than a van, and the practices we build to.
- Batteries
Lithium vs. lead-acid for your rig
An honest comparison of LiFePO4 and lead-acid/AGM batteries for vans, RVs, and trailers — usable capacity, cycle life, weight, charge speed, cold-weather behavior, and when each one is the right call.
- System design
How we size an off-grid system
The methodology we use to size a mobile off-grid system, from daily watt-hours through battery bank, recharge sources, inverter, and the wiring and monitor that hold it together.
