2 Bank topology
Solar & Battery

Series and parallel connections change battery bank voltage and amp hours in different ways.

Enter identical module ratings and the proposed arrangement. Compare the ideal bank values before checking the manufacturer's permitted configurations.

01 / GET STARTED

How to use Battery Bank Series and Parallel Calculator

  1. Enter module nominal voltage and module capacity.
  2. Enter modules per series string and parallel strings.
  3. Select Calculate result. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
02 / A CLEARER WORKFLOW

Why choose this tool?

The arithmetic view helps distinguish added voltage from added parallel capacity.

Before you use the result

Arithmetic assumes identical compatible modules. BMS, permitted series or parallel arrangements, protection and balancing require manufacturer and installer review. This is not wiring approval.

03 / COMMON QUESTIONS

Questions about Battery Bank Series and Parallel Calculator

Is the arrangement approved for wiring?

No. Module compatibility, protection, balancing and manufacturer limits require qualified review before installation.

What should I check before using Battery Bank Series and Parallel Calculator?

Check Module nominal voltage, Module capacity, Modules per series string and Parallel strings. Use the exact units shown beside the controls and replace any example values with your own inputs.
