Got a temporary system started to run the basics while we finish out the house and setup a proper 2-3kw system.
Read more about the setup and how to size your own on the blog http://hellopeople950.wixsite.com/thehappyhermit/single-post/2017/06/28/Installing-a-small-Off-Grid-Solar-System
Understand exactly how much power is stored in your batteries and how much of that you can use on a daily basis. This video also covers how power gets from your solar panels to your batteries and finally to your appliances. You will learn how to size your solar system according to how much power consumption you expect to have.
