What Is Low-Voltage Living?
For our purposes, low-voltage means producing 12-volt direct current (VDC) and using it at that level whenever possible. For technical reasons, low-voltage electricity limits the size of a given appliance and the total amount of power that will be available in a day.
Electricity Storage
The weakest link in any low-voltage electrical system is almost always its batteries. Why? Well, usually because they’re the wrong type for the application, they’re improperly sized, they’re poorly monitored, or they don’t receive adequate maintenance.
Low Voltage Wiring
As we’ve already suggested, there are certain technical limits to the size of appliances or generators in a low-voltage electrical system. Because wattage is a function of both voltage and amperage, when one goes down the other must rise. Unfortunately, amperage determines the carrying capacity of wire.

Why are higher voltage batteries better?
The advantages of higher voltage batteries are significant. You can save money in wiring, reduce voltage drops, reduce the stress on the battery (as the current demand decreases for the same amount of power delivered), and components such as relays and motor brushes last longer. There is a lot to be said for higher voltage batteries.
