How To Create A Solar + Battery + Inverter Scenario

Use the solar-hybrid scenario when the system must support loads and also benefit from solar production during the modeled period.

When to use this scenario

This scenario is ideal when solar is expected to support day loads, partially recharge the battery, or reduce the amount of utility or shore-power charging needed.

Solar fields

In addition to the battery and inverter inputs, pay close attention to panel watts, panel Vmp, panel Voc, average sun hours, installation efficiency, cloud factors, and battery recharge settings. These fields affect both the required solar energy and the advisory string guidance.

Battery recharge behavior

The battery recharge percent field tells GridGap how much of the previous night's battery usage you want solar to replace. If a user has help from the grid or shore power to charge batteries, solar may only need to cover a supplement rather than the full recharge burden.

What to review after calculating

After calculation, review the Solar tab, Solar Controller tab, warnings, and the cloud sensitivity section. That is where you will see whether the clean installed panel count, string guidance, MPPT requirements, and solar surplus or shortfall make practical sense.
