Battery Inputs Explained

Battery fields tell GridGap how much energy is available, at what voltage, under what battery chemistry assumptions, and with what discharge limits.

Core battery fields

Battery size is the entered unit capacity. Battery capacity mode controls whether the user is entering capacity in kWh or Ah. Battery voltage is the unit battery voltage, while inverter system voltage is the target bank/system voltage.

Battery chemistry matters because chemistry profiles can influence defaults and interpretation. Max discharge percent is effectively the allowed depth of discharge. Lower usable discharge means more total battery is needed to support the same energy demand.

Advanced battery fields

Temperature oversizing factor adds a conservative adjustment. Enable Peukert, Peukert exponent, and rated hour capacity are technical-mode style controls for batteries where discharge behavior changes meaningfully with current draw.

If the app offers discharge current mode and related current overrides, those settings are for more advanced control over how battery current assumptions are derived.

Battery installation fields

When installation planning is enabled, battery-specific installation fields expand the estimate: cable one-way length, use of busbars, battery-to-busbar length, forced string count, cable material, cable type, voltage drop target, installation environment, protection preference, and isolation poles.

These fields do not turn GridGap into a final engineering design tool. They add indicative planning guidance only.
