Reading Battery Results

The Battery tab is where the storage idea stops being abstract. It shows how the energy burden turns into a bank with a layout, a depletion level, and a reserve.

Start with what the battery is being asked to do

Do not jump straight to total battery count. Start with the amount of energy the battery must deliver, then follow how the app turns that into a practical bank.

The first cards help you confirm the battery basis used in the scenario: Battery Unit kWh / Ah, Battery Entry, and Battery Voltage. These are useful checks when the final answer looks larger or smaller than expected.

Follow the requirement chain

After that, the tab walks through the requirement build-up. The key cards are Battery output required, Nominal capacity required, Temperature adjusted capacity, Peukert factor, Final required battery capacity, and Required system Ah.

Read these as a sequence. They show why the battery answer is often larger than a quick estimate.

Then look at the physical bank layout

Once the requirement is known, GridGap turns it into a bank layout. This is where Series count, Parallel strings, and Total batteries become important.

These cards explain the shape of the bank, not just its size. That matters because the answer has to be buildable from whole batteries in a sensible configuration.

The next two cards, Actual installed capacity and Actual usable capacity, tell you what the rounded bank really provides after that physical layout is applied.

Pay close attention to depletion and reserve

The last part of the tab is often the most practical. Depletion percent shows how hard the scenario pushes the battery bank. Reserve Wh and percent shows what remains after the scenario demand has been covered.

A mathematically valid result can still feel tight if depletion is high and reserve is thin. That is usually the point where the battery side deserves another look.

Use the battery graph properly

Below the detail cards, the battery graph gives a quick visual split between used capacity and reserve. It is there to help you feel the result, not replace the numbers above it.

If the graph shows very little reserve, go back to the reserve and depletion cards. That usually means the battery side is close to its practical limit for the current scenario.

What makes a battery result worth reviewing again

Review the battery result again when the bank count seems surprisingly high, when reserve is thin, when depletion is heavy, or when the warnings tab suggests the assumptions need caution.

The battery answer should never be judged on total battery count alone. Read battery count with configuration, usable capacity, depletion, and reserve.
