Appliance Energy Consumption Chart

Use the chart below to estimate the Average Daily Watts consumed by each appliance/device.

To calculate the Average Daily Watts for a given appliance/device:

Lookup the Estimated Energy Usage per Hour
Multiply Estimated Energy Usage per Hour times the estimated hours of operation per day, for the device.

Appliance Power Requirement Calculator

To keep things simple, just download the following worksheet to calculate your daily and peak power requirements – click here to download an Excel copy for your own use.

How to use the worksheet:

Enter the number of appliances (‘# Devices’) you need to keep running and the amount of time you plan to use each device every day (‘Hrs/Day (ea.)’).
The worksheet will calculate your total Energy Storage (Wh/day) and Peak Power Rating (Watts).
Use the Storage (Wh) and Power Rating (Watts) to select the right solar generator for your home backup, outdoor/RV or portable charging requirement.
