A one-line diagram should include all specified electrical design information about a proposed system, including solar modules, inverters, interconnection point, disconnect switches and meters. If batteries, subpanels, and/or other generators are part of the design, these must be noted. In order to correctly meter solar production, the metering configuration should match one of the diagrams found by clicking here.
