You are discussing solar PV installation options with a homeowner who is considering a grid-tied system for their suburban home, and an off-grid system for their vacation home. Thinking about the PV system components you outlined for a grid-tied system in the project quiz, describe how the components differ for an off-grid installation. What components from the grid-tied system would not be needed in an off-grid situation? What other components would be added on?
