Change battery charging direction

Last modified: 2026-05-07

Because there is no industry-wide standard yet, you can specify whether the negative or the positive power values coming from your battery should be interpreted as battery charging.

Prerequisites

User group technician or higher

Steps

At system level , go to System settings > Calculations > Battery charging direction.
Select an option for how to interpret the power values of all your system’s batteries:
- Default: Negative power values are interpreted as the battery being charged, and positive values as battery discharging.
- Reverse: Negative power values are interpreted as the battery being discharged, and positive values as battery charging.

Note

Even if you use user-defined terms for battery charging and discharging, you can change the charging direction in the menu. The basic structure of your term formulas remains the same.

Select Save.

The selected option is now applied. Values are flipped in the Battery portlet and the Self-consumption chart.
