How To Create A DC Battery + Distribution Scenario

Use this scenario when the loads are DC loads and solar is not contributing during the period you are modelling. The focus is the battery and the DC distribution path.

When to use this scenario

This is the right fit when the version contains DC appliances only and you want to test how the battery supports those loads without solar in the modelled period.

It can suit DC-led setups such as small off-grid systems, vehicle or marine DC loads, communications equipment, lighting, pumps, or other loads that do not need an AC inverter path for this option.

Before you start

Check the appliance list before creating the scenario. If the version contains AC appliances, GridGap will block a DC-only scenario. Remove the AC appliances from that version, or choose a mixed AC/DC scenario if both load types belong in the same option.

Set up the scenario

In the Scenario editor, add the DC appliances first. Then choose DC - Battery + Distribution when selecting the scenario type.

With the guided route, let the app create the load groups, enter the worst-case usage hours, and then use Continue to Scenario Settings. GridGap will show that the scenario is ready before opening the starting settings. With the blank route, use Start with blank scenario settings and choose DC - Battery + Distribution in the blank scenario modal.

What to focus on

Start with the battery assumptions and the DC system path. The result depends on the appliance demand, the battery settings, the available charging assumptions, and the DC distribution requirements for the selected loads.

Keep the usage hours realistic. DC loads can look modest one by one, but long operating hours can still create a heavy energy demand.

Calculate and review

After calculation, review the overview, battery, DC distribution, charging, and warnings sections. Those areas show whether the DC load set and battery assumptions are still practical.
