How Much Power Do Your Home Appliances Use?
The table below shows approximate appliance wattage ratings for the items listed. Keep in mind that your specific appliance may vary and this table is just a guideline. For more accurate appliance wattages, check the rating on the appliance or use a kilowatt meter to measure the energy usage. Multiply the hours used on an average day by the wattage listed below. This will give you the watt-hours consumed per day.

When sizing your DC to AC power inverter, be sure to plan for the surge rating on your appliance. An 800-watt washing machine has a surge rating of 3000 watts, be sure to choose a power inverter that will handle the surge rating. In this case, a 1500 watt inverter should do.

*To estimate the number of hours that a refrigerator actually operates at its maximum wattage, divide the total time the refrigerator is plugged in by three. Refrigerators, although turned "on" all the time, actually cycle on and off as needed to maintain interior temperatures.

Task lighting typically consumes less power than overhead lighting because task lights give you more flexibility than a large central light. Timers are great for making sure lights are not left on longer than intended and motion sensing lights will only run when you really need them. You can find DC timers and LED Floodlights on our website to optimize your lighting efficiency.

Secret sources of power consumption
A phantom load is energy consumed by an appliance when switched "off." Some electronics feature displays or LED lights or are continuously searching for a signal. These loads consume very little power, but over time they waste a lot of energy. Unplugging appliances such as TVs, DVD players, stereos, etc. will save power and reduce the overall amount of power you have to produce and store.
Using a simple power strip that can be unplugged or switched off is an easy way to eliminate phantom loads.
