AltE Store is a great resource for all of your off grid electrical needs. They tell you what you need and how to install the system.
Here’s a basic overview of the components needed for a stand-alone system and links to additional library.
For more detailed information on solar modules, see our article Components for your Solar Panel (Photovoltaic) System and look at our selection of solar panels.
The two main functions of a charge controller are to prevent the battery from being overcharged and to eliminate any reverse current flow from the batteries back to the solar modules at night. See our article Components for your Solar Panel (Photovoltaic) System for more detailed information on charge controller functions and features.
The battery bank stores the energy produced by the solar array during the day for use at anytime of the day or night. Batteries come in many sizes and grades. The inverter takes the DC energy stored in the battery bank and inverts it to 120 or 240 VAC to run your AC appliances.
