Beware that energy-saving appliances' power supplies may put very high frequency noise and harmonics on wiring.
Avoid blenders, pool pumps and other appliances with variable speed motors. Use single-speed motors.
Some folks believe that Stetzer or Greenwave filters (which have only one capacitor) improve sleep and health--even while they increase magnetic fields, draw current and do nothing in a DC system. Before you buy, know the return policy.
Reduce your power use by reducing your use of electronics. Use solar ovens. Replace electric heating pads and blankets with hot water bottles. Beware of children (and adults) getting cuddly with electronic toys. Don't just change your power source. Change your lifestyle.
How do we create safer solar power?
Option #1: Keep the system DC
Use 12-volt batteries to charge electronics. Use a universal adapter that regulates DC voltage output and polarity to a device. This is not an AC-DC inverter. A universal adapter requires reading the operating voltage and polarity listed on the device, then setting the adapter to match. While this is easy, if done incorrectly, you can damage the device and/or adapter.
You may need to retrofit wiring, depending on the power draw of your major appliances and electronics.
Get DC-powered appliances, such as an on-demand water heater that uses two D-cell batteries for ignition (and no pilot light). Boat and RV dealers familiar with 12-volt-powered appliances may be especially resourceful. Use well-ventilated propane refrigerators, stovetops and ovens.
