How to Size a Battery Bank
Wanneer dit van toepassing is
Use this guide when you need a defensible first-pass storage capacity before BMS specifics, chemistry datasheets, and charge profiles are fixed.

- 1Quantify daily load energy and decide how many days of autonomy you truly need.
- 2Pick a maximum depth of discharge consistent with the chemistry you are screening.
- 3Include inverter/charge efficiency and temperature derates if your calculator exposes them.
- 4Round capacity to realistic module strings only after the energy requirement is stable.
- 5Validate against charge/discharge power limits in a dedicated power study when stakes are high.
Voorbeelden
- Cabin off-grid bank next to a load profile spreadsheet.
- UPS-style backup for critical loads only.
Vermijd dit
- Using nameplate Ah without voltage base for energy comparisons.
- Ignoring efficiency losses on both charge and discharge paths.
- Oversizing autonomy without revisiting load reduction opportunities.

Veelgestelde vragen
Is this for lithium only?
The logic is chemistry-agnostic at screening level; final design still needs vendor limits.
Does it include aging?
No. Treat results as early-life screening unless you apply your own fade margin.
