Reading Battery Results
The Battery tab shows how the scenario's energy burden turns into a real battery bank. This is where a rough storage idea becomes a practical answer with capacity, layout, depletion, and reserve.
Start with what the battery is being asked to do
The battery result is not only about total battery count. It starts with the amount of energy the battery must deliver and then works through the steps needed to turn 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 rather than isolated values. They show why the battery answer is often larger than a quick manual estimate. The app is not only asking how much energy must be stored. It is also accounting for how that storage behaves inside a real battery system.
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 final answer must 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. On the other hand, a bank that looks large may make more sense when you notice that reserve margin is helping support a demanding use case more comfortably.
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 and read them carefully. That usually means the battery side is close to its practical limit for the current scenario.
What makes a battery result worth reviewing again
Give the battery result a second look when the bank count seems surprisingly high, when reserve is thin, when depletion is heavy, or when the warnings tab suggests assumptions need caution.
The battery answer should never be judged on total battery count alone. The better reading is battery count plus configuration, usable capacity, depletion, and reserve.
