How to use a single‑line diagram template.
- 01Identify the power sources and loads
List the DC sources (batteries, PV, rectifiers) and the loads that will connect to the distribution panel.
- 02Draft the one-line layout
Sketch the main bus, breaker positions, and wire runs showing how power flows from source to load.
- 03Add ratings and labels
Annotate voltage (120V DC), breaker ampere ratings, and wire sizes based on your load calculations.
- 04Generate and refine the diagram
Use the tool’s drag-and-drop symbols to build the SLD, then adjust layout and export as PDF or PNG.
Questions about single‑line diagram templates
What is a single line diagram for a DC distribution panel?
It’s a simplified schematic that uses single lines and symbols to represent the power path, protection devices, and loads in a DC electrical system, all on one drawing.
What components are typically included in a 120V DC distribution panel SLD?
Common components include a battery bank or DC source, main breaker, bus bars, branch breakers, charge controllers, and load connections like lights or inverters.
Can I use this diagram for off-grid solar systems?
Yes, these diagrams are suitable for 120V DC off-grid solar setups, especially with PV charge controllers and battery storage, as shown in the examples.
Is the generator free to use?
Yes, the diagram generator is free and works in your browser. No signup is required to create and download your single line diagram.
