Product: HOMER Pro

How do I model meters, switches, circuit breakers, charge controllers, transmission lines, or other components in HOMER?

HOMER is a powerful economic decision-making tool to aid in conceptual system design. The component definitions are kept as simple as possible, for ease in modeling while maintaining accuracy of results. You should include cost and efficiency of small components like switches and meters in the definition of primary components, for example you can include cost and approximate efficiency of a battery charge controller in your battery model.

Specific details about HOMER's calculations are available in the program help documentation, under the "Help" tab in the software. See the category titled "HOMER's calculations". HOMER isn't a CAD software for power systems. For some simple systems, a HOMER model is adequate. For more complex systems, detailed design of the power electronics and controls is necessary once you have used HOMER to choose your system architecture.
