Summary. Most homes use 120-volt and 220-volt systems that have remained mostly unchanged for over 100 years. The fact is that electronic devices and appliances have changed dramatically over the past hundred years and power sources have also changed.
Smaller homes can take advantage of these changes and benefit from the savings, convenience, safety, and efficiency that the new technologies have to offer.
Some devices such as lights, fans, mobile phones, computers, shavers, and portable radios will operate just fine using a 12-volt power source. This is because many devices are designed to operate in cars, boats, and RVs. You can even find televisions, refrigerators, and other appliances designed for 12-volts. For these reasons you may want to equip your home with 12-volt electrical service. Since many devices work on rechargeable batteries, it’s possible to not have wiring at all and just use solar rechargeable batteries instead. Here are a few benefits of working with a 12-volt electrical system.
