How Charging Works In GridGap

This tab is about recovery. The battery may cover the load, but it still has to be charged again in a sensible amount of time.

What the Charging tab is doing

Charging results tend to feel more practical than theoretical because they answer a daily-use question. Can the battery be restored in the window you actually have available.

A battery can look fine in stored-energy terms and still be awkward to live with if the recharge plan is too slow.

Energy to replace

Start with Energy to replace. This is the battery energy that has to be put back after the scenario run.

If this number is high, the charging side has serious work to do. If it is modest, the result is usually easier to manage.

Minimum and recommended charger size

Next, read Grid charge hours and Charger efficiency. Those two values shape the problem. One tells the app how much time is available. The other tells it how much of the charging power actually reaches the battery.

From there, GridGap gives you both minimum and recommended charger sizes: Minimum charger W, Minimum charger A, Recommended charger W, and Recommended charger A.

DC distribution scenarios can show DC charging outputs instead, including DC minimum charger values, recommended DC charger values, and DC recharge time. Read those against the same recovery question: can the battery be restored in the time available.

The recommended figures are the better starting point for real hardware comparison. The minimum figures show the lower technical floor.

Recharge time and charging window

Grid recharge time is often the most useful card in the tab. Read it directly against the available charge hours.

If recharge time is comfortably shorter than the available window, the charging side is usually in decent shape. If it is close to the limit, the system may still work but with less margin. If it runs beyond the available window, the scenario is telling you the recharge plan needs attention.
