Why do my two batteries show different percentages?

Why do my two batteries show different percentages?

It’s normal for two batteries to show slightly different percentages when viewed separately.

  • SOC is calculated from voltage, and each battery does this individually.

  • Small differences are expected, but when combined, the system balances them.

  • As long as voltages are aligned, you’re still using the full combined capacity.

Solution:

  • A calibration can bring percentage readings closer together.

  • Firmware updates may also improve accuracy.

Troubleshooting:

  • If the voltages are more than ~0.5V apart, a calibration is recommended.

When to Contact Support:

If large discrepancies persist after calibration.

      It’s normal to see very short periods of import or export on your graphs, even if you expect your battery to cover demand. Your battery “ramps up” when demand increases (e.g., when you switch on a kettle). During this ramp-up, you may briefly import ...
