A 100Ah 12V LiFePO4 battery stores 1,200 watt-hours (Wh) of usable energy. That’s enough to run small appliances, refrigeration, lights, fans, and electronics for many hours. The chart below gives realistic runtimes based on real-world off-grid usage. 100Ah Battery Runtime Chart...
A 200Ah 12V LiFePO4 battery stores 2,400Wh of usable energy, which is double the capacity of a 100Ah battery. This is a common size for cabins and off-grid systems because it can run refrigeration, lights, electronics, fans, pumps, and small appliances...
Daily watt-hours (Wh) tell you how much energy your appliances use in a full day. This number is the foundation for sizing your battery, solar panels, and inverter. Luckily, it only takes two steps and one very simple formula. Daily Watt-Hour...
LiFePO4 (Lithium Iron Phosphate) batteries typically last 10–15 years and deliver 3,000–6,000 full cycles, depending on usage. This makes them the longest-lasting and most cost-efficient battery chemistry for off-grid power systems. A well-maintained LiFePO4 battery can easily outlast AGM, gel,...
Depth of Discharge (DoD) tells you how much of your battery’s capacity you’ve used. A battery drained to 50% DoD still has half its energy left. Understanding DoD helps you make your batteries last longer and size your off-grid system...
Powering a cabin off-grid requires four main components: solar panels, batteries for storage, a charge controller, and an inverter. The exact size depends on what you want to run daily, but the chart below gives a fast beginner-friendly benchmark so...
