Method & assumptions

How is it calculated?

Series strings add voltage while Ah stays the same. Parallel strings add Ah while voltage stays the same. Nominal Wh ≈ Vbank × Ahbank. Avoid mixing different ages, chemistries or capacities.

Example

Example: Four 12 V 100 Ah batteries arranged 2S2P produce 24 V, 200 Ah and about 4.8 kWh nominal energy.

WHAT CHANGES THE RESULT

Check these before using the estimate

Electrical and energy calculations are not final designs by themselves. Load profile, conductor conditions, protection, efficiency and local codes must be considered together. Sorsana tools are intended for preliminary sizing and scenario comparison.
