The Economical approach to system sizing.

Then look for any appliance between say 1000 to 2000watts, and work out how essential each of these items are.

It is easy to record the power output of each of your appliances on our appliance usage chart on page 28. Now for the important part; how long will you realistically want to run each appliance over a normal day (if you overstate your true requirements here, your system can become oversized, and cost far more than necessary). For help in sizing your system, have a look at our usage tables at the back of this catalogue.
