Battery measurement unstable

[erich-maier]

Describe the bug

Hello all,

i have the situation that my energy board did not show me the battery in or battery out measurements. Sometime it is shown, sometimes not.

The battery works absolutely correct. All other settings are also fine. I have found something similar in an other project. binsentsu/home-assistant-solaredge-modbus#281 could it be the same?

I use:
Core: 2025.3.3
Supervisor: 2025.03.3
Operating System: 15.0
Frontend: 20250306.0

Expected behavior

Have look into the device of SolarEdge batteries

Check your logs for messages about Battery Import Energy went backwards or Battery Export Energy went backwards.

This is a SolarEdge bug if you see those messages.

yes I found that messages in the log files. But that did not match with timing of unavailability of sensors ...

[WillCodeForCats]

That's why they go into unavailable state, because watt-hour sensors should never go backwards.

You can choose how you want to handle that condition with some options:

https://github.com/WillCodeForCats/solaredge-modbus-multi/wiki/Configuration#battery-options

You can turn on Allow Battery Energy to Reset or set Update Cycles to Reset Battery Energy to a value greater than zero. The default is to change to unavailable state when the energy goes backwards instead of possibly displaying bad data. Changing these options can display bad data, but it's your choice if you would rather see it go backwards (even if it might be wrong) or change to unavailable state.

I don't personally have batteries so I can't recommend the best settings for this.

There is more information under Battery Energy in Known Issues:

But this is not an integration bug.
