Diagram Description
The diagram illustrates a typical solar power system setup. It shows a solar panel connected to the RICH SOLAR RS-PWM40P charge controller. The charge controller is then connected to a battery, and a load (represented by a light bulb) is connected to the load terminals of the charge controller. This depicts the flow of energy from the solar panel, through the charge controller for regulation, to charge the battery and power the load.
