Offgrid is a daily audio summary of the latest ideas, innovations, products, and hard-won lessons for living autonomously and becoming more self-sufficient in energy, tech, food, water, shelter, and everyday systems. This 3-story episode draws from OffGrid and moves through cabin system lesson, propane heater sizing, always-on inverter load.

1. Cabin System Lesson

This one is less about equipment specs and more about the reality of a first off-grid stay in a cabin that has only a generator for hot water and a mini fridge. The practical concern is not survival but how long complete beginners can handle limited plugs, no house Wi-Fi, and a routine that depends on planning instead of background convenience.

2. Propane Heater Sizing

This one gets into a very off-grid plumbing detail: how to feed two outdoor tankless propane water heaters when one unit is modest and the other is a very large 180,000 BTU load. The post already had the heaters mounted and the water side plumbed, so the remaining problem was regulator choice, hose sizing, and whether a pair of 30 pound cylinders is realistic for the larger heater.

3. Always-on Inverter Load

This story turns a pet appliance into an inverter design question. The setup is small right now, with a portable Goal Zero kit handling lights and phone charging, and the new concern is whether an automatic litter box justifies leaving AC power on all day.
