Off-grid & energy independence

Load math, solar sizing and the arithmetic behind living without a grid connection.

Off-grid is a different problem from weekend camping. You empty the pack and refill it every day, so rated cycle life and solar input ceiling matter more than headline capacity — and the units that win for camping are frequently the worst choices here.

Work out what you need with how to size a power station, then check what you will actually recover from panels in solar recharge in practice. For the ranking, see the best power stations for off-grid living.

Two guides underpin the rest: rated vs usable capacity explains why the box overstates what you get, and LiFePO4 vs NMC explains why "4,000 cycles" means different things from different manufacturers.
