Apart from a method of generating renewable electricity — whether it’s wind or solar — the core part of any completely off-grid setup is the battery pack that saves the energy generated and allows it to be used when the wind isn’t blowing or the sun isn’t shining.
Forklift batteries are popular for this, as are other types of chemical batteries. The Lithium-Ion batteries that power cell phones could be ideal because of their energy density, but their cost is way too much to make them viable (despite Tesla’s efforts with the PowerWall). So a modern battery with the qualities of Lithium-Ion but the cost of old-fashioned lead-acid is something of a Holy Grail for preppers.
